Diamond pistons - waste

Boring block - waste

160* - waste

stock cam with ported heads - waste

not knowing if it is tuned or not - more of a problem.

My suggestion. Go get the PO and find out is going on 110%.

Then, go buy a stock short block, stud the heads, re-gasket and get new fluids, port the heads, run a cam of some sort because porting the heads with a stock valvetrain would be a waste. Start off with a 3.4" pulley and go from there when you have a way to tune it, because a 3.1" will be too small. Probably running the factory injectors static as well which is no bueno.

So yea
