350 olds build questions..

[High Roller]

350 Olds Piston options:
350 W-31 Sealed Power Forged 10.5:1 Part # L2320F (standard bore)
Sealed Power Forged 10.25:1 hi-comp Part # L2321F (0.030" over).
Forged pistons are also available from
Diamond
CP (4.065) #BO7000-008
Venolia Dome #5840, Flat Top #5830
Probe SRS +0.30” (4.087) #14475 9.48:1 w/72cc heads
Mondello +0.30” (4.087) #2020+.030 9.51:1 w/72cc heads

Heads: As long as you have casting code "2" - "7" heads, you are OK. Toss them "8" emission heads. because of huge chamber size and the latter because of the odd-sized valves. If you are running the stock cast replacement 7.9:1 pistons, you will have to mill the head 0.0450" - 0.050" (maximum) to return the compression to an actual CR of 8.9:1. And fully port and polish the 350 heads. Add W-31 valves (2.000" intakes and 1.625" exhausts). Run Harland Sharp Aluminum Roller Rocker Arms, Isky #200-AGP Guide Plates, Comp Cams “Hi-Tech” 3/8" pushrods.

I also agree sell the 650, and go with 750 holley/or q-jet. run a 160^ stat, and go with 22-2500 stall, 3.42 gears

The old formula rule is (hp=$) how fast you wanna go?? but if your only planning on $500 budget dont expect too much.

I don't see why ppl keep telling you to get rid of the 650 carb...there's no reason this wont work well for you. i've run well into the 12's with a 650DP

Big difference between an e-brock 650 and a holley 650 dp.

what about a E-Brock 750 or just get a holley?

 

[dogsht]

For a track car get a Holley for a driver get a Q-jet.

Listen to Vern on his recommendations. I've had a q-jet, holley, and e-brock on my car. For the street car definitely q-jet, the holley has a bit of a temper. If I had were going to daily drive my 442 like in the past I wouldn't run the holley.

BTW Vern thanks for your mention of my build.
