318 parts list

Just to recap.......

318 just using bolt-ons without machining the block at all

Yeah it's stock auto(904) daily driver

trying for 300-375..........block only has about 105k )

This is the dilemma.......If it's 1977 and it has 15k on it you could bolt on/in...

A fresh set of milled 1.88 "J" heads, with a thin gasket.
A cam in the 230*@.050 range.
The required torque converter.
Air-Gap intake.
650/750 carb.

....and probably get in your range.

But, it's 2012 and it has 105k. Spinning this engine in the required 5500/6000 range repeatedly is gonna make for a very unhappy shortblock in a hurry.

In the long run, i think the best solution is to allow for the time to pull it and have it freshened with the appropriate pistons, rings, brgs, oil pump, etc.
