cleveland heads on 400m

[jbeery78]

Curious who has done this, i have some questions like- what heads did u use, what intake, headers, cam, etc etc. I already havr a lumpy cam in my 400, im curious if i can use my 400 aluminum intake or if ill need something different.

I was checking into it a bit before. Theres alot of  info about it on ford460.com  or 351clevland.net I do know you have to rework the intake to make it work on the heads port matching mainly or get adapter plates. you want the 4 barrel heads there closed chambers. most of the 2 barrel heads are open chamber heads  and without any quench pad are prone to detonation but there are australian closed chamber 2 barrel heads my uncle has a couple sets of em. good luck with the search

not all 4bl heads are closed chambers, there are open chambers to that are 4bl heads.

Yea i see that there are several variations of each head, 2bbl or 4bbl. Im continuing my research, i think itll be a cool project since my 400 is pretty tight. Ill definitely check out 460ford tho, i know theres a lotta info there. We have a chassis dyno at work, so im thinkin ill do a couple pulls before and after and maybe start a project thread about the buildup.

best bang for the buck is cleavleand pistons bushed for the 400 rods  did this years ago flat tops and stock heads cr was 10.5 to 1

Yea i read about that too, i saw some serious power made on a fairly stock motor with those pistons. Thats another option on my list haha
