Crazy 318 Stroker question

I knew a dude that ran an honest 318 and a six pac. Preety damn quick.
Adding a stroker kit to make 390 cubes no longer makes it a 318. The stroker kit adds cubic inchs via the crank. It add's mad amounts of torque.
But should you stroke it to 390 cubes, all that you wrote after that is worthless babble. Though not bad for a 318, just not a 390.

Since your new to engines by your own words, I would suggest a few books. Hot to hot rod your MoPar by Larry Shepard and the MoPar engines book (For small blocks) by MoPar Performance.

Once you get through those, theres more, but stick to those first and then come on back with the questions. The books will really help put things into place for you.
