I have a fresh 318 that is almost ready to go.... Just got to get the intake to fit - it's a little too wide right now for the heads that are on it... I may have to have a little milled off it to get it to fit right...
I'm considering tossing that in the 66 Valiant wagon instead of the 360 I had originally planned...
If I'm not happy with the 318, I can always build a 360 later and swap it in....
