Got any more info on your 400? I would say they would work but they will need the steam holes drilled in them.

 

Right now its just the block, when its built its gonna be my daily driver and i eventually plan on sparyin it with 100-150 shot of nos, not very often tho

 

Just be sure to combine a 67cc had with a pump gas friendly dished piston to get a compression ratio that will work on the street every day. If you perfer flat top 400 pistons get the large chamber 70+cc version of this head.

Watch the spring seat pressure if you're using a hyd camshaft in your 400. This head is marketed as a serious street bracket racer head set up for a .550" +- lift racey solid cam or roller. More spring pressure than nessessary will just shorten the camshaft life of a flat tappet hyd in a daily driver. its all about balance. Summit has the same head available in different assembled packages for different end purposes.
