I just got a quote for a 331 and was wondering what you guys thought of it? Let me know what you think it will put out for HP, TQ and times. Will this be a good steet setup? Let me kow If there is anything you would change? Thanks in advance, JD

331 stroker

3.250 steel crank
5.315 4340 I beam rods
Probe forged Pistons flat top 10.5.1
28 oz balanced
sfi professional products 28oz balance
billet flywheel 280z
roller 302 block
new cam bearings, freeze plugs, pro machined block
custom hyd roller cam installed and dergeed in
cam spec 533/545 @50 226/232 @50 112 lsa
billet timming chain
cam block plate with arp bolt
pro comp alum 190cc heads
1.6 ss roller rockers
hardened push rods
head studs
fel pro head gaskets & rear main seal

I have a performer intake, bbk70mm tbto put on this also. What else should I get to go with this setup? Oh and I have a 94 gt coupe with a t-5, alum. driveshaft, and 373 gears.

I would use a Scat 4340 forged crank, not the RPM crank, 5.4 rod lightweight I beam w 7/16" ARP rod bolt upgrade, not a 5.315, Romac ultralight 28oz damper, Fidenza 28oz aluminum flywheel. Liteweight rotating assembly spins up real fast. and I would do a custom cam designed around the head and intake cfm flow among other things, from FTI, Cam Motion or Jay Allen. That 226/232 dur is too small, IMO, go with a 230/240 dur, or just go with off the shelf cam like Comp Cam XE282HR, one bad ass cam.

I would go with at least a Performer ll intake but a better choice would be the Holley Systemax ll port matched to the gasket and the heads.
 
are you staying NA with it or do you plan on boosting it? with that CR, i bet NA.

looks like a good start, but:

what do you know about the heads?
what machine work are they doing?
main girdle? if so you should have it align honed with the girdle torqued down.
windage tray?
hone with or without torque plate?
deck or square the block?
high volume or standard oil pump?
standard or high capacity oil pan?
what headers?

fwiw, i have some stuff left over from my aborted 331 build you might be interested in.
