Update: It hasnt been easy, every corner I turn, every guy I get a price from etc. etc. points to one thing... 350 swap. The best I can do, is to NOT spend any significant money on a 305 and do head porting and intake porting by myself. The EQ 305 heads flow about what stan weiss says, but they are in fact $715.00 assembled. Mix that with a vortec intake for $375 and it's a no go.
So- I bought a 350 vortec 882 block and crank. It needs new rods and pistons etc. but at least I wont be throwing my $$ away.
I figure a 355, flat tops, 270 cam, vortecs and a decent exhaust with TPI would get somewhere. The turd gen cars are so heavy, it should be mandatory anyway.
