Budget 318 build

Number two and number three are the same.
If it were I .....
Rework the 360 heads and mill them down.
Then do number 1 with KB slugs and zero deck it.
Off the exhaust manifolds, as large as a pipe as you get on it. 2-1/2 would be awesome. “H” pipe the dual exhaust.
340-ish cam????

Ooooo boy! Actual specs would be stellar

Read them again, option 2 swaps the 318 heads back in, and option 3 reworks the short and adds the 318 heads. Basically, I am wondering if adding big chamber/port 360 heads in a small 318 is my biggest anchor. Especially if I am looking for power down low, where 318 cubes are the most challenged. Increased velocities, something the 318 heads will offer you in spades, combined with the increase in CR, will give you better mixing down low -- where the bigger port/smaller velocity 360 heads are over-sized for only 318 cubes and will only come to life in very high rpm high flow need, something my 318 will never see with an automatic and 3:23 gears. Cam specs at this point, are minor, relatively speaking.
