451 Build For the 67 JC B'Cuda

If the OP buys a block that has the original main caps on it then there is no reason to spend time and money swapping caps. Assuming he is working on a budget that is one place he can save money. He can cut at least $1000 off of his list by ditching the girdle and aftermarket caps and switching to a flat tappet cam. He'll still be able to make 550 to 600 hp without any trouble.
