Greetings to all!

Im looking for head recommendations, chamber size and the such. Here is what I have so far
350 block, tanked, mag'd cleaned an bored .060 (was orig 030)
cleaned, reworked original crank, mag'd in perfect shape
eagle 5.7 I rods
speed pro pistons (bore 103.124, compress dis 1.425", Pist Head Vol +5.00cc)
Comp Cam Hydraulic Flat Tappet Duration 270/270, Lift .470/.470
Edelbrock highrise intake manafold
edelbrock performer series carb 600cfm

its pushing a 87 firebird with an auto tranny in it. may never see the strip but that doesnt mean I dont want as much HP as possible.

I need to match the heads now to get as much hp as I can and this is where I get lost per say. can anybody help me out here?

 

With that low duration and life I would go for something like a 170CC vortec head or something similar. If you can handle a 64ish cc chamber. I probably would not go over 180CC on the intake runner.

 

hmm something like a AFR-0918,, or the edelbrock performer edl-60995 than should work. although Im not opposed to changing out the cam and dropping in a different comp cam, say the cca-12-564-4... thoughts?

 

What is your block deck height?
Stock is 9.025" Even if you decked it by .025", which is typically referred to as "zero-decked" with stock pistons, you'd still have a horrible 0.135" deck clearance with those pistons. You need something closer to a stock compression height piston (1.56")
I would stop right where you are and reconsider.

 

I will measure that tonight, this is my first engine build and Im working through alot, thanks for all the advise, please keep it coming. if it is at the 9.025, than I will need to order new pistons,,, Ill know more later on this afternoon.

 

so Im unable to measure the deck height properly as I dont have the proper tool. But I did put the piston in, bolt it down and measured the piston height gap with it at TDC, 0.146 best I could with some feeler gauges and digital caliper. with that said,, it looks like a deck height of 9.011. So it looks like ill be ordering new pistons, speed-pro with a 1.565 compression dist, with a piston head volume of 3.40cc. 3.48/2=1.74+5.7+1.565=9.005. uuuhhhggggggggggg...

 

did you decide on heads for this combo yet?
