Need some advice on major future mods.
I'm trying to put a budget together, based on the specific parts I'm going to go with.
Mods so far:
True Dual Exhaust, No cat, Targa Mufflers
Free Mods w/ K&N, other basic stuff
Future Mods:
Stealth Ram w/ custom plenum
52mm TB
Hooker Headers
Stronger U-Joints
Stronger Half-shafts
ZR1-rims and tires
Cam?
Heads?
Valve Train?
What is the oder of restrictions on the intake? MAF, Filter Housing, etc.
What cam should I go with?
Heads? Get them ported or just buy new ones (i have cast iron)
Valve Train? New RR's, Springs, Rods? Taller Valve Covers?
Do I need a stronger crank?
My goal is to try and get 325 RWHP nat. aspir. Any suggestions would be great. Am I going the right way, or should I just get it stroked? I want to keep is streetable, (9.5-10.5 compression, idle between 700-900).
TIA

The stock MAF flows in the 550cfm range, a ported MAF flows around 750cfm, you might be able to use all the 550 but it'd be really tough to use all of 750cfm on a 350. MAF and intake are the real restrictions, not the TB or filter housing so much.
Ditch the stock heads, definitely.
I might go with AFR 190s to get that power goal, but Id leave it to grump as to what cam to really pick for it. Something with about 215-220 degrees of duration should get it though. Valvetrain parts go with the cam, so it would depend. Cam companies will recommend what springs, but also get the RR and Ti retainers.
The stock drivetrain can handle alot of power, as long as you use the correct Spicer joints. You wouldnt really NEED the CF halfshafts, but its probably still a good idea.

Disclaimer: I haven't built any engines...
I'd go stroker for streetability, that or a 400
Holly Stealth Ram
AFR 190's or 195's
Roller cam at least 224* intake and .550 lift
Hooker SuperComps
stronger trans if it's an auto
Anybody else???
