(unevenly) timed flow also come into play in the exhaust. An equal firing 
interval for each banks gives best performance because it allows the use 
of tuned exhausts. The disadvantage is that the engine balance is badly 
influenced (4 cylinder like instead of V8).

is the down fall, also the car wouldn't sound as if it had an American 
V-8 in it,(SLEEPER), but I haven't seen any commercially available with 
cam shafts to match.

		They don't have what I am really looking for. I am 
currently running one of their dual plane manifolds, the Edelbrock 
Performer.

	Here are a few sites that are involved in Chevy intake manifold 
design....

	Good luck with the big block.

the firing pulses are even on each now and therfore make most current 
headers perfect for this?
