UZ- I, too, have been asking these questions since this forum started. After much discussion I have come to this conclusion: Because of GM's design, the 305 will be very expensive to modify in order to get it into the 350hp area (my goal). For the dollars spent to obtain this HP I can just do this (I'm saving my pennies
Ram Jet 350 PFI
Engine Part # 12495515
<LI>Horsepower: 350 hp @ 5200 rpm
<LI>Torque: 400 ft lbs. @ 3500 rpm
<LI>Compression Ratio: 9.4 to 1
<LI>Block: Cast Iron 2-Bolt, 4.000" Bore
<LI>Crankshaft: Nodular Iron, 3.480" Stroke
<LI>Heads, Chamber Size: Vortec, 64cc
<LI>Valves (I/E): 1.940"/1.500"
<LI>Camshaft, Lift (I/E): 0.431"/0.451"
<LI>Dur. @ 0.050" (I/E): 196/207 degrees
<LI>Intake: Ram Jet PFI[/list]
All of my stock accessories (alternator, power steering pump, air conditioner, etc) will bolt right on, so I won't have to spend any extra $$$ on that stuff.
This crate motor and others (like the 502cid 502hp engine) can be found at Scoggin-Dickey in Lubbock, TX. ( http://www.sdpc2000.com
I'm not telling you that you shouldn't mod your engine, I'm just saying that, for me, there was a choice between major $$$ for mods or major $$$ for a crate motor. The crate motor won.
