Cam Question for Ed or Jay

Get ahold of Ed Curtis at Flowtech Induction or Jay Allen at Camshaft Innovations and have them grind you up a custom.
Ok I'll give it a shot. I picked out a cam from Comp Cams, but I know everyone will say its too small for a 351W. Its a 208/216 duration at .50 and has a 112 lobe sep with 108 centerline. Lift is .533 and .544. This is a roller cam to be used in a 1995 5.8L block. This engine is to go into a 1990-93 Mustang GT.

Anyway my main concern is to keep the engine streetable, with excellent emissions, excellent gas mileage, work with stock computer, street range power band (1200-5500 rpm), and build the motor more for low to midrange torque then trying to get top end power.

My engine combo is:

1995 roller block 351W bored to 357 cubic inches.
15.9 cc dished forged pistons giving 9.64 compression with the heads
AFR 185 heads with 2.02/ 1.6 valves and air injection
Pedestal mount roller rockers- stock 1.6 ratio
stock crank with Eagle I beam rods- stock stroke
TFS-R 351W EFI intake
75mm BBK throttle body with 76mm BBK mass air sensor
BBK long tube headers with 2.5" collector
2.5" exhaust running 40 series Flowmasters and BBK shortened H pipe with cat converters
MSD 351W EFI distributor and stock ignition running regular spark plugs
K&N air filter in stock box

The last 351W engine I did- I put a Crane hydraulic cam into with 216/228 duration and the best mileage I could get from it was 200KM on a tank of gas. With that cam- the engine was rarely operating in its intended power band. This is why I'd rather go mild on the cam as long as I maintain street power and economy. The car will be a T-5 tranny stock and use 3.08 gears in the rear.

So Ed or Jay- what camshaft profile do you recommend?

Ok let's get his straight. You are worried about gas mileage in a 351 that has every mod u can do to a motor? I just don't get people like this. You should go buy a prius hybrid and be done with it. If gasmileage is that important to you then u have made bad decisions in life. Gas isn't anything I budget. If u get a better job gas mileage won't matter.

I think you missed the point I was getting 200km on a 15 gallon tank of gas. No Im not concerned with gas mileage to the point I'd not even do this swap, but I do want better mileage then 7-8 miles per gallon which is what I got from my last motor. This is a far cry from the 18-24 miles per gallon stock 5.0Ls get and even lower then my first 351W swap where I got 225km on a 13 gallon tank of gas. The difference then was the cam I used in the first motor was a mild rv cam with 204/214 duration.

Something I have realized over the last 2 weeks is you really never get to talk to Ed or Jay. You send them your build sheet and they pick a cam profile that has already been previously designed by them. For some reason I thought they would "specifically" cut a cam to my combo BUT they just pick one of "their" designed cams that should work well with your combo. I have sent more than one email with questions and they never gave me the time of day. It just said send money and you'll get your cam in two weeks or whatever. The whole thing didn't feel right, I'd rather research and get 95% there and save money instead of hoping the grinder and I are on the same page. No bash on any of the custom cam guys here. If any of what I said is wrong then please enlighten me.

You really have no clue. Having dealt with Jay he is more than willing to discuss every aspect of your car, not just the valvetrain, until you are both on the same page. I talked to him in many emails and several phone calls and it was a great experience; I would definitely do it again.

As for picking "one of their previously designed cams," you should really not go throwing things like that out there when you dont have a clue.

So how is it a custom grind if they just pick one of their pre-made cams already? Even Comp does that and they aren't custom grinds. I'll stick with Comp Cams. Cheaper.

Because (as I understand) they have certain cam specs designed for specific setups. It's not like they sit and design an entirely new cam because joe blow has a h/c/i 351 that's been done 100 times before. You think you're going to get a "one off" cam for only 3xx dollars?? I wouldn't exactly trust the comp guys either, you talking to a cam guy or some kid?
 
#17 · (Edited)
You are partially right. I am sure they (cam designers) have different lobe profiles that can be used for many setups, but you can do a lot by moving the placement of the timing events and changing lift numbers. Optimizing timing and lift events for each head/intake/stroke setup (while using lobe profiles they are familiar with) is what makes the cam custom.

Although, I will add, this is my understanding of it.

IF you are only getting 7-8 mpg you need to have someone tune it. The cam is not the reason for the milage. My 408 running 3000 down the highway got 15. This is with a very loose 5800 converter.

The cam you have picked is small but will work fine. IMO just give Rick Anderson a call and he will tell you what one of his cams will work best with your combo for FREE. Just have to purchase his Billet Hyd cam & Springs that match. One stop shop! Oh BTW dont be suprised when Rick himself answers the phone.

People post their custom cam specs all the time, and I have never once seen some else say they have the exact cam? Maybe you don't have all your facts straight on that assumption?
 
#19 ·
Only time i seen people post there cam specs or cam card is when they are trying to sale it. There are only so many 302,306,331 & 347 combo's that are so different.

For the street you want a shorter duration cam to give lots of low end torque and keep mileage in check. There is a reason why auto manufacturers didn't go too wild in the cam when making stock motors. I think too many people build motors for top end horsepower, not low to mid end torque. I still think the cam I chose fits the needs I have picked out. I want a torque monster NA engine, not a top end screamer.

I think you will see good mileage with that combo but a custom tune for your car will go a lot further than picking a small cam for your motor to get better fuel economy. I am not trying to bash you at all I would just suggest you PM some of the custom tuners on this forum as well as the custom cam guys. You can have the best of both worlds with your car.

just keep asking, eventually somone will crack and help you pick an awsome cam. I was going back and forth thru emails with a memberr off here adna fter two weeks he found me a great cam. I made a thread about ti and buddy rawls stumbled in and explained exactly why the cam would work well with my combo

off the shelf cams are garbage, for about 50 bucks more then a ots cam you could have one that will actully work! buddy rawls has done a few for me with great success

i highly doubt the 1000's of people that have OTS cams have them "not work"

Custom Cams are nice. But if you do your own research, learn how timing events, lift and duration all come in play with the rest of your combo, Im sure you could get a pretty decent OTS cam. If you want something precise, then go custom for sure

OTS cams are good if you are buying used. I got the cam in my sig for $150 and my motor makes over 300whp with box stock RPMs and a ported Cobra.

If/when I ever do a big stroker build I will for goddam sure get a custom though.

I'm talking to buddy right now about a custom cam, I like that we can actually exchange emails and discuss things. IIRC he charges 35 to spec a cam, don't quote me on that though.

How do I get a hold of him?

I just went through this on Hardcore50.com with another person. Rather than rewrite it all, I'll just cut and paste.


The “system” used to get through all the Email inquiries and package quoting is pretty simple. The first priority is with those customers who have sent in their payments for our products and services. After all, these are the people who are actually paying the bills to keep this business running on a daily basis. I will then tackle the requests for information or pricing and those are handled on a first in, first out basis. Though every attempt is made to answer as many requests as humanly possible during the day, the time required is very limited because of existing customer orders that must be filled. That’s why I prefer to do this in the early mornings, before the day’s schedule in the shop gets too filled up.

When I provide an Email quote to a potential customer, the overall combination is checked and any “red flag” issues are covered during the first round of communication. Once a customer agrees to the pricing and lead times, the specifics of each package are designed and priced out in more detail. It is then up to the customer to decide if they wish to pursue purchasing the final product by sending in a payment and all the information on their project.

When payment is received, the customer’s package is then put in the work schedule and, as pieces are completed, they are shipped out. Those that do not send a payment are saved and stored in a "completed" file for a period of thirty days. In a perfect world, every customer request would result in an order and we would have quite the business, however this is not the case. Not everyone steps up to the plate and makes a purchase.

Sometimes, highly specific quotes take longer than consumers think it should, but I do my best to get them done. As you can imagine, we do get quite a few requests for all types of combinations every day, and I do take time to review each and every one. Though there are some who feel the response time is sometimes long, so far, the “system” appears to be working as there are a lot of completed orders making there way to our customers.

In spite of the fact it seems like there are just not enough hours in the day, and days in the week and weeks in the year to get all the orders processed, these orders do manage to go out the door to all our customers. Successful results from the use of our packages are well documented and because of that, the demand is very high. So, in order to consistently provide my customers with these successful combinations, it will require more time to get each and every one of these projects completed properly and shipped out. I can't spend all day on a keyboard.

I truly believe the end results our customers are obtaining are worth the time and effort. Results don't lie.

Hmm, I have done cam business with both Ed and Buddy, and both cams worked bodaciously in weird combos....and I have seen Ed for prolonged periods of time at once, so I can prove he exists.....:D
