Hey guys im new here and just wondering on how yall think a 406 small block will do with 64cc double hump heads with 488:488 lift cam with 302:302 duration with1.5 roller rockers and a dual plane edelbrock intake im planning on putting it in a 87 dodge ram 50?

 

be careful you can end up with more compression that the gas that is available ! you better have a machine shop run the numbers especially if you change pistons .

By what we figured its got 11.5:1 compression i had been driving it with a .450 lift cam i just want to go up to .488 lift and the dual plane intake

 

it aught to make some good horse pressure for you just keep preimem gas in it to keep any detonation down to a low roar as it warms up it will make a runner !
