I recently swaped engines in one of my high mileage chevys and have an extra block... The block is a 1996 chevy vortec 5.7 liter or 350 small block... It has the two intake manifolds on it, one being where all the fuel injectors are.

I was wondering if I tore the block completly down oil pump, crank, harmonic balancer, timing chain, cam shaft, connecting rods pistons, bearing caps etc... If I could buy one of them engine rotating kits from summit racing and turn that engine into a 383 stroker? I would have to bring it to a machine shop and have them overbore the cylinder walls by 30 thou.

I ask this cause I havent yet to see a stroker with the air intake system a regular vortec 350 has... They all seem to have that tbi set up.

Thank you

You can do that, you will have to stay with your stock intake and vortec heads if you do. You will also need to send your ECM out to get reflashed for best results. You can reflash it your self with a hand held unit, but it will not be optimal.

I am currently looking around for a mid 80's gmc or chevy k series truck. I have always liked that style and I allready have a ton of the 90's model chevy's. hopefully I can find an 87 with a bad motor and little to body damage that has a 350 engine in it. running or not tear the motor apart and rebuild it into a stroker, I know a few guys who paint vehicles and do body damge that will just charge me materials to paint and so on. One of my friends has machines in his barn that can re-ground valves and polish cranks and that. If I find a reasonable one I will nab it make that into a stroker with a 4 barrel holley.

I realy like the look of those chevys a fresh paint job and power upgrades would make a bad ride.

But if not I got the vortec block ripped stripped down yesterday to either rebuild to original or make a stroker.
