I am having a 400 block, crank, rods, and heads givin to me. Block will most likely need 30 overbore. Crank looks perfect.
First question is rod length. I thought I wanted a 6 inch rod motor (must think in budget terms!!!)
A buddy laughed off 5.7's, saying no difference from the 5.656's the 400 came with.
But that leads to question 2, pistons. KB hyper pistons for stock rods, flat top or dome. For 5.7 a selection of dishes, flat, and domes.
Which starts question 3, heads. The small chamber heads on the current motor would do for now, the large chambers with the 400 could be done cheaply enough too. ( some day HOPE for decent aftermarket heads!!)
Will I have a hope of 350+ hp, and 350+ torque???
Any thoughts???
