do you want the horsepower or is there a specific 1/4 mile number your trying to run?

 

check out members david clafin and mgerman....

 

Just looking for the HP. Its going to be just a fun street car..Ive rode in a buddies 347 notch and he made like 380rwhp. Its one fun ride for sure!

 

david's car makes 358RWHP/346RWTQ and i'm pretty sure mark's car makes around 430-440 at the crank.....

 

306, 5.4" rods

Uh,that's not a 306 then,that's a 347 unless I'm missing something here.

 

long rod 306......post #13

 

My typing sucks, call me any time (916-289-8340) i am local went 11.42@ 119XX with a 306 that i built.

same car with a stock shortblock went 11.92@115.XX

 

Your on CAFords right? I think I bought parts from you before!

 

Ok,gotcha!

 

i made 333whp on my s trim at 10psi with all stock motor and maxing out my 30lb injectors. could have made 380 easy.

 

If your not limited by class, why not build a 347? There is a big difference between a max effort 306 and a 347 but the cost is not that much more for the the better engine. Guess which one is better.

 

My na 306 made 344/359 at the rear wheels eight years ago with the factory cobra intake. These days it wears a holley systemax II. It may not have the big dyno numbers, but it has very good averages.

 

I'm in the same boat.. after shopping around for different builders and parts costs.. I'm pretty sure fordstrokers is just gonna be building me a 331 or 347...

 

Mine:

89 GT bottom end (factory crank, rods, forged pistons)
Trickflow stg 3 cam
Edelbrock performer rpm heads
RPM intake
holley 750 dp
Scorpian 1.7rr's
Longtubes..

Should make 350whp 350whtq at 6500 rpm.

 

my roommates 88GT

302 stock shortblock
windsor jr iron heads
systemax intake(no spacer)
comp ots nos cam
65mm tb
24's + proflow maf
1-5/8 shorties, 2.5 OR-H, flowmaster CB
stock T5 trans, king cobra clutch
3.73's + U&L control arms
hoosier slicks

with a 150 shot it runs 11.20's @ 122 and 12.60-70's off the bottle. completely daily driveable and he doesnt have 3k into the whole set-up.

 

stock 302 shortblock, 9:1CR, AFR 165 or TFS track heat 185 head, RPM ll intake, custom FTI cam. easy 350/350 to the tire, NA.

 

When I was running the 306 combo, I had a pretty simple set-up: Cobra intake, AFR165's, 10:1 CR, FTI camshaft, FMS shorty headers w/ Mac H-Pipe and stock cat-back. It was a very fun street car set-up, low maintenance.....and everybody wanted a free ride - LOL. I never had it on the dyno or to the track to give you any numbers......but it was definitely a lot of fun for the amount of money I had in it. Before you start buying parts, be honest with yourself about what you want from the car in the future and plan accordingly. This may prevent you from buying the parts twice as you want more from the car (if that is the plan).

 

I basically want a fun street car with little maintenance. Im leaning toward going 306 with AFR 185's, Holley systemax with spacer or RPM2, FTI cam and long tube headers with maybe some 4.10s.

Ive pretty much got my suspension in. UCA/LCAs, welded boxes upper and lower, sub frames, big breaks etc.

I dont have to have the fastest car out there. Just wanna whip up some bolt on ls1's, get groceries, and be able to take the lady out in one day.

 

Unless your limited by class, I don't know why anyone would take the time and mony to build a performance n/a 306 when for a small amount more they could build a lighter and stronger 347.

 

I just think of it like this. If people are making 350ish rwhp with a 306 and its totally reliable why go to a stroker? I wont need to buy a stroker kit or anything like that.

 

Stroker will be easier to make the power, will make more tq, and do it all at a lower RPM...

This is of course speaking in general.

A 306 street car making 350 rwhp is not insanely hard by any means, but it would be much simpler to do it with a stroker.

This is also coming from a guy who wants to build an NA 306 with worked E7s and a Cobra intake.
