I see you have the 2031 why not just use that one? If it was me I would use it instead of buying another one. All those cam's are about the same. But I would say go with the b-21 if you do decide to buy another.

 

actually thats my old car, just never took it out of the sig. Don't really want to go 2031 again, it had some minor pushrod length issues.

Bahahahahaha...

I think the builder is the issue.

 

Not to hijack, but what type of pushrod issues did you have with the 2031? I'm looking into getting that one for my mild s-charger combo. Did you use it with the 1.7s?

FWIW I heard that the TFS1 may create some idle issues when installed on a mild combo.

 

I've heard the vaccum issues with that cam too.

On the 2031 I had to do custom pushrods. Still wasn't perfect, and coulda just been my car. None the less still had to mess with it a fair bit. and yeah that was with factory cobra rockers 1.7

 

For a benchmark, I have the Steeda #19 in mine with 1.6's and GT40P heads. The P.O. planned on adding a blower, which I want to do down the road, as well. It dynoed 260/298 on bad plugs and wires with stock airbox, MAF, and TB.

Full mods and dyno graph are at the link in my sig.

I've had both the Steeda 19 and the XE270-112. The XE-270 blew away the Steeda IMO. Keep in mind there are two versions of the XE-270. One for 1.6 and 1.7 rockers. I used the 1.7 rockers. You should match the springs to the cam not the cam to the springs. lol. As for the #19 I really didn't like it one bit. It's light on bottom for sure, and dosen't make enough on top either. Both cams were ran with Performer heads, gt40 style intakes on 306 cid engines.

I don't have any dyno numbers, but ere is the results of a 306 with performer 5.0 heads explorer intake and the XE270 cam.

Is the #19 not considered a "blower" cam, and if so, could this be the reason it seems "soft" for a N/A application?

EDIT: From Steeda's site:

"Product Details
Steeda proudly offers the #19 Cam, similar to the popular #18 Cam, but with a slightly wider lobe separation angle for better vacuum at idle which is required by the more sensitive 94-95 Mustang processor. This cam features a split pattern which favors the exhaust side, and a wide 115° lobe separation for low overlap, making it an excellent choice for supercharged engines."

I had a 270 in my car and it was very nice.

 

IIRC the b21 has over .520 lift

I am liking the #19 so far but I have only been driving it far a week with my new motor. But it is a little lazy under 3000 but it doesnt really bother me. i did buld it for boost

 

The springs are good to .542" lift not .520" I just talked to TFS yesterday about it because I need to upgrade the springs on my GT40P heads. Also, they said stick to the 1.6 rockers with the stage 1 cam which is what I have because it could cause P to V issues and would put the springs near max capacity.

 

I was "talked into" the #19 because it was in an SN95 not for a blower or not. A blower will make any cam work better.

Even with a blower I'd still take the XE270 over the #19. You need some bottom end to get them spun up. Unless your using a KB style.

 

Ran the tfs1 with unported gt40's off a 95 cobra and stock gt rockers. I did a good bit of research on what the stock gt40's like cam wise. They like a split that favors the exh. Lift that is in the .490-.500 range with a lift favoring the exh in the .09-.12 range and dur favoring the exh. around 2-4 more.

My combo that was a stock shortblock, gt40 heads (before they were ported), ported stock gt lower was a NICE setup. Ran a 13.2 @ 102 the only time at the track with that combo 100% untuned.

I would say the TFS with 1.6's

or

the Steeda19 with 1.7's.

 

I have the Comp XE270-14 with a P1SC and 40p's and it idles alot better than the TFS-1. No Dyno numbers or track times with the blower yet. It'll be another month. Got rained out:crying: Drivability is excellent as well. Cant speak for the steeda.

 

Well, the xe270 will be at .544 lift with 1.7 rockers, the b-21 will be at .542. And the steeda 19 will be at .510. So out of those three it looks like the steeda 19 is what you should use based on your springs.

 

Have you thought about the E-cam? NA my ole GT40P combo ran 12.80s @ 111 all motor. Could easy go low 12s with some suspenesion.

 

Well I am not looking for an e cam, just for the simple fact that I will be putting it in a 94 car. I like the xe270. with the xe lobe profile, will I be going through valve train parts like crazy? Still looking at the TFS1 though. Just wish I didn't have a brand new set of 1.7rr. Guess I could sell them and get some 1.6rr. Still looking for opinions.

Thanks,
Shawn

 

Have you looked at the Lunati 51014 or possibly custom depending on your budget. I have the Lunati with 1.7's and like it so far. It idles good, sounds mean, have down low power and good vacuum. The specs:

Advertised Duration (Int/Exh): 284/292
Duration @ .050 (Int/Exh): 218/226
Gross Valve Lift (Int/Exh): 1.6's- .500/.510 ---1.7's - .531/.542
LSA/ICL: 112/108

 

Also when do I need to start worrying about possible P/V clearance issues?

 

People run all these cams with no clearance issues but you still need to check to make sure. There are many factors that could cause you to have issues with clearance with your setup.

 

Well after researching and researching some more. I don't the the XE270 will suit me(although I wish it would) Even with the one desighned for 1.7RR it still puts me at .544 lift and there is not really much point in going with that much lift on a regular set of GT40 heads. I can go with the crane valve spring kit, which is supposedly good to .550 lift. Still run into theroretical valve p/v clearance problems though

The steeda would work well, but everyone says it's got a really soft bottom end.

THe B-21 I have searched on, but just can't find much inof on it.

I keep coming back to the crane 2031. I've had it and know, seems like one of the few choices in my situation.

I know it sounds stupid to buy a cam around the rocker arms, but I have researched these rocker arms to death. I know they will work with my heads, my valve covers, my springs, and my pushrods,. If I go get some 1.6's I have to do that all over again. Plus I have to buy them too. Just still looking for some info.

Thanks,
Shawn

 

You can keep your 1.7's since you have them already, no sense in buying more if yours work fine. I personally would pick between either the steeda 19 or the cam you currently have. The lunati is good but the lift with 1.7's are right at what your springs are rated for. I'm probably a bit too cautious in that regard but I don't like to push the envelope so to speak with max lift on springs. With that said I think your best options out of those listed are either the steeda 19 or the 2031. But if you get something from comp cams it could cost around $300, which is what a custom cam costs.

 

The 2031 would be a great choice. I have had great luck with the 2030 (1.6 rockers). I used it with iron GT40 heads cobra intake in my old 89 LX. With stock 3.08 gears I went 13.0s at 104 mph still in 3rd gear! I have not used the 2031 but they are very simuliar like the two versions of the XE270.

 

Yes price is a factor, the 2031 is $190.00 versus some of the other that all the way up to and over $300. Which is custom territory. I've had this cam before, and was fairly happy with it. It rides that fine line of being just enough without too much for the heads. Just wanted to get a little more from the package this time around. I think the 2031 is my best bet though. It's essentially the same engine that was in my cobra. and it made 277 to the wheels, with a enough blow by to launch the dipstick accross the garage. I would like to get 280 or up out of this one.

Thanks,
Shawn

 

I have the 2031,its not the best for my 94..The lope at a traffic light it starts off ok, but after 30 seconds the computer can't keep a good idle and it wants to stall and some times it does.So now I'm looking for a good street cam, then I'll put on the SC I have.I did put the idle plate on,only helped so much..If I remember back on my other 95 I had the CC 264 w/114*lobe separation,but it was a 5spd.Man do I miss that car,did a H/C/I and a powerdyne-9# and it ran great on the road.Sometimes the stock cam is the best w/1.7rr's on a 94-95 when using the factory computer on a automatic car- for I ran that combo on my other 94 GT I had, for it had good street idle and a fair amount of power..
