Ok so the 350 is in and broken in enough to pull a few full throttle runs. It hauls pretty nicely, but I'd like to add a bit more before I'm satisfied (or broke). Here's what I've got:

350 bored .030,
flattops, 882 heads (cleaned up, no porting)
with the deckheight and head gasket ~8.9CR.
Comp Cams XE 262 grind.
Edelbrock Performer Manifold, Stock Qjet. (B hanger, CK rods)
Edelbrock TES headers (!!Lg4 version!!) /w some sorta aftermarket cat, feeding into some sorta 3" catback, noisy "flo-pro" muffler.
3.73 gears, phat tyres, manual tranny.
Timing set at 8*. Did I miss anything?

Anyhow, I'm assuming the bottlneck is at the Ypipe collector/cat conv, so I'm looking at a replacement Flowmaster (2.25" in / 3.00" out) Y-pipe collector with a high-flo cat, or maybe just a test pipe as its not required, but most likely a high-flo since un-catalyzed(sp?) exhaust stinks and sounds a little too *******.

Better ideas? Anyone?

Later,
Hype.

i would say ur exhaust is holding u back. and i wouldn't go with flowmaster unless u just want them for sound, they don't .FLOW as good as many others out there

Try working on your ignition curve. You don't say what you have for a distributor but if it is HEI go to the Tech Articles on this site and get the one dealing with them.
