Here is what I know (or think I know):

350 C.I originally 350/300HP
stock pistons
487 heads (76cc 2.02/1.94)
Edelbrock #7102 cam (adv. dur. 308/318 @ .050 lift/ .488/.510 lift)
Edelbrock Performer carb #1405 600 CFM
Edelbrock Performer EPS dual-plane intake
Hooker Comp headers, 1 5/8 tubes

I'm not positive about the cam. The "soundbyte" of the XE292 cam on the Comp Cams website sounds nearly identical to mine FWIW.

Thanks in advance!
Randy

You'll need the flow numbers on your heads to get an accurate answer. If you can find them, I'll run it for you :cheers:

I may be out of luck. I can't find anything that gives the flow numbers for these heads. The "head guide" stated these are the best flowing of the big-chambered heads. Another site said that they are similar to the new 492 double-hump heads too. They do have the guideplates on them too.

Thanks!

Ok, it looks like 205 intake and around 143 exhaust flow numbers at .500 lift with the 882 heads which are similar.

Thanks Darin. I was hoping the rest of the mods made back the HP lost in the head swap. I'm still thinking of going with a good 64 cc head to help the compression ratio.
