My car has the stock TH350 tranny and converter with the standard 10 bolt open differential, (not sure about the gears). I have been looking for a big block but the cost would be more than I can afford right now with having to get different a/c brackets, power steering brackets, a radiator, and everything else involved. That plus the gas mileage would kill me. I drive a lot of highway miles to work and move halfway across the country every 3 years (I'm active duty Navy). I have been leaning towards the 383 option. On www.enginekits.com I can pick up a balanced 383 stroker kit for $688. In addition to that, I would need to get the block machined, get new heads, and probably change the cam and I would be all set. Am I missing anything? I talked to a buddy who said I could probably get the machine work done for around $250. Does that sound about right? What heads and cam should I use if I go this route?
