400BB Engine
Yes its a mopar engine a great motor to build with.The combo,s to build this with is alot,and can put a smile on your face if you do it right.Its the same shape as all the big blocks,except that this motor is about 3/4 of a inch shorter in deck height.It can interchange parts and can have other machined down to fit and make awesome power.If any can get a hold of one for a good price, you buy it,put it away,and work from their,Mrmopartech
