good combo for over 400hp?

[i_love_my_stang]

im building a n/a high compression 331 stroker, and i want to pump out like over 400hp, ive decided to get a cam from ed curtis but whats a good proven combo to reach that number, these are the pistons im using, is AFR the only head that will do that or is their other combos as well?

Afr 185's. Port job and a valve job. Really big cam. Trickflow top of the line intake ported. And you might be able to reach 400 at the flywheel

I'm running a 331 with 185 AFR heads, Comp Cams 35-522-8, Edelbrock RPM II intake, 30 lbs injectors etc. I put 374 rwhp & 360 torque & ran 11.80 at 116 in a full weight 95 GTS. I think you would be happy with the 185's. Good luck

It is going to be easier to hit your 400HP goal with a 347. You didn't say whether 400 was RWHP or at the crank.

I don't know if you have emissions there but I would look at AFR 185s or the new 190's depending on when they are released. Shoot for at least 300in/225ex flow

Run a cam with at least 224 degrees duration on the intake. You can probably run more though. You'll also want to stick with 112-114 lobe separation. Ed can really work wonders allowing you to still pass emissions and make great power if need be.

Don't be afraid of compression, run 10.5-11:1.

Holley Systemax intake.
AFR 185 or 190 heads
Custom Cam
30lb injectors
75mm throttle body
tune


You should be at 400 or real close.

I would do a 347 for the same money its a no brainer.

Also I would look into the TFS TW Fast As Cast heads. stock exhaust pattern and loaction but better valve placement.

the pistons i have will run a 10.37 compression ratio with a 58cc combustion chamber, and i bet if i get a cam from ed curtis that should bump up the compression a bit more should'nt it?

What sized compressed head gasket? how far is the piston in or out of the hole? how far down is the top ring land?

And finally how does a cam effect the compression ratio?

 

[Addermk2]

I run those exact pistons in my "short rod" 347. 10666-030.
My static compression is 11.25:1. Runs on 93 octane.

if I were you, I'd run a larger head with a custom cam, and something along the lines of a victor 5.0 intake, maybe even a TFS Box-R

 

[fastgtfairlane]

the cam has nothing to do with compression

Runs on 93 octane.

You suck. I wish we had 93 octane around here.

like the edelbrock victor jr. heads?

It doesn't affect static compression. It affects cylinder pressures, a cam with lots of overlap is gonna bleed off cylinder pressure, so you run more compression with larger cams to make up for it.

We have 91 too. I've run the car on 89 before, but I didn't put the boots to it at all.

210cc vic jr's are pretty nice heads. I was going to run AFR 205's on my car, then I picked up a set of worked Canfields on the cheap.

We have 94 muahahahaha...

 

[Addermk2]

so why would you wish you had 93???

 

[foss_94gt]

we got 94 too

 

[LAFENATU]

Addermk2...

Cause he can run more timing.

 

[Venom351R]

More timing = more power. We used to have 93 here until the $4 a gallon gas hit last summer now all we can get is 91.

exactly but he's talking about static compression and asking if a cam can help bump that. The answer is no. Cam controls cranking and running compression.

idk why i always do that... but I get Paul, and LAFENATU mixed up when they post
