Well I got off track but I agree, the logic minded 318 guy will eventually realize that performance with a 318 isn't impossible its just more logical the the 360 .
I agree that, a 318 will sound good with a cam but those down in the hole pistons and sub 4 inch bore leave much to be desired. Now someone will say and I've heard many times the bore don't mean nothing but Ill say it means this you cant use large valves and a high lift cam. Second the heads the castings are smaller in stock heads and you cant port a 318 casting to 340-360 size ports you'd grind through. You still need a decent crank and rotating assembly to go to 6 K and above. My 318 was great on the street but it was a mid range up to 5- 5500 street car I'm not going to say it was a performance engine even though I had a cam headers and 4 barrel on an otherwise stock LA 318. My 340 is a different monster even at idle. You just know it runs and you feel the torque just rapping the throttle.
