i was able to get a 327 that had previously been bored over to a 331 and now is in need of a rebuild... I was wondering if i could get a budget build done and still be around the 350 hp with about 400 tq and what parts i should consider i have looked at kieth black pistons and im wanting a roller cam so any input would be greatly appreciated

im thinking kieth black pistons 11:1 would be a good start with a set of stock forged rods i already have a holley street dominator intake and everything else is stock

Can be made into a 355 if you use the 350 pistons, rods and crank. Think the rods are the same.

I would keep it as a 327, as per your sig it's going into your RX7??

A 327 will rev much better than a 355.

I would built a strong bottom end, topped off with a real nice set of flowing heads. Monster cam as well.

what heads would you recommend im trying to keep it on somewhat of a budget im planning on revving to 6500 rpms or close to that and how big of a cam are you thinkin?

If you want power, add cubes, if you want a lower torque and a higher revving motor that cost more to make scream, keep the 327 cubes.

400 tq ... not likely n/a

I loved my 333 (.040 327) ... but it was rev happy for sure (tfs heads, 236/236 cam)
gear it low (4.10+)

well the car im throwin it in has 4.08 gearing and i have the stock heads... how good could those heads flow with some cleaning up and getting better chamber and intake runners? the motor is going in a car that weighs 2900 pounds and im wanting to get it in the low to mid 12s so im thinkin that 400 hp and 400 torque should get me in that range

would 180cc intake runners be good for this setup i believe 195 would be too much or am i mistaken?

Scat Pro Stock I-Beam Connecting Rods
Keith Black Hypereutectic Pistons- Flat top 2 valve
Hooker Super Competition Headers- 2063HKR needed due to fitment
Holley Street Dominator intake manifold
SummitŪ Piston Rings

Thats the beginning to my parts list does that look like a good start?

If you can get good hook out of the car it wouldn't take 400hp/torque to get mid/low 12's. Good luck with project, it'd have to be a fun one to drive.

I'd suggest a set of patriot heads, preferably the 180cc sets.

I put a set on my 383, and they REALLY woke it up over the iron heads.

i have chosen the vortec 906 heads with a valve job done with an air gap manifold vortec heads specific and a comp 262 cam

only problem with that is, a 327 likes to rev, past 6500, Vortec heads dont like to go above 6000 too much, much less 7000. So you are kind of holding back power. It should go to 6500 if you get the right cam, but it wont like it as much as if it had bigger heads, say a 185 cc int runner.

what is your goals with this motor? drag, street,etc.?
the 906 will work well for street car. with that manifold.
it will be no race motor but it should run pretty good. u will not be able to build a hi rev'n motor with those heads, esp. if using stock pressed in studs.

u will need to have machined for use with screw in rocker studs, etc. all that adds up.might as well go with aftermarket heads, will be in same price range after machine work and trying to get everyhting to work correct with vortecs

if its just a street motor, keep it under 6000 rpm. and go with a flat tappet cam.
dont spend u money for roller retrofit cam swap.
better off going with a vortec 350 roller block and heads. and build that
