thanks for the ideas.

it's tough to build on a budget even when we do the work ourselves.

what do you think of lunati cams compared to comp and crane cams?
any thoughts on the new edelbrock 383 top end combo?

I think the 170cc intake runners are too small. I'd want something around 195cc, compression around 10.5:1, an Edelbrock Performer RPM dual plane, then spec the cam accordingly.

ok, well i have a dual plane performer on my current motor now. so spec-ing out the cam to match that makes sense.

195 does sound like a little more room to breath for the power i want. who makes a good cast iron head in that size? i want cast for strength and reliability. not to mention low cost.

Aluminum heads are every bit as reliable as iron heads. There are guys putting serious boost to 23* aluminum heads without problems. But, as you said, they are more expensive.

Dart makes some good iron heads. They have 180cc and 200cc intake runners and I believe have 2.05 intake valves. I'm sure they're available in different chamber sizes as well.

What are you doing for a cam? Flat tappet hydraulic or something more aggressive?

the budget builder in me says to go with a nice hydraulic flat tappet cam setup.

[I]but the performace lover in me says make that thing full roller with everything forged.

i think i'll have to go with scat 9000 bottom end with the money going to roller goodies and iron heads.

do you know what my machine shop could do for me with stock iron heads? can the open them up enough for me?

Darknight,

You could go with "Fast Burn" heads from GM, 210cc intake ports, Vortec Style.

With a .509/528 lift and 222/230 duration cam @.050 lift made 425HP on a 383 with 9.7:1 compression. Recommended carb was a Demon 750.

Said the heads would support well over 500hp.

Just my.02$.

thats a good idea. i'll have to look into the fast burn heads.

we might try for a higher compession like 10:1 or 10.5:1.

man, the options are endless. it's all about the money, right ?!?!?
