Sbc or bbc?
I have a 383(it's suppose to be) but it has ****ty 416 heads and performer intake on it. Well I wanted to buy some dart iron eagle heads and performer rpm or air gap intake so it will come alive. I could possible buy a fresh stock build 396 with a 427 cam. The motor has only been ran on the stand. I know the guy real well and he is a great guy and great mechanic. Buy the 396 or heads and cam? Truck is just a toy/daily. 200-4r 4.56s 29" tire

Its a toss up the small block you can keep your trans,But the big block would need a new trans.If you don't care about gas mileage get the big block.

Stick with the smallblock. A 396 is the baby of big blocks and with decent heads, the 383 will smoke it. Biggest problem with the 396 is it's tiny bore - valves are too close to cylinder walls for decent breathing. If you're going to spend the coin on a big block, get a good 2-bolt 454 block, Scat cast crank and Scat rods, open chamber 781 or 049 heads, small dome pistons, and buy stock in a tire company, you'll need it.

If you are at all concerned with gas mileage, then forget the 396, especially one that has been hopped up. If you don't care about gas mileage, I would rather have a stock 454 out of a truck. I have had two and have run them for decades with no engine work, except for replacing the notorious "soft cam" and resulting busted pushrods on the 73 I had. In a 1/2 ton pickup a stock truck 454 engine won't use much more gas than a 350, and it has way more power and acceleration.
