I just noticed you are in AZ what part?
As for the engine a mild 383 will make some very good tq, after all you have to get the weight moving. Many are suprised at how well a low hp engine does as they never gave thought to tq. Finding the right balance is the key. I think you will do very well with the set up. Spend the time to get the engine dilaed in..... Ask marv about that
