gettin my lt1 bored and stroked

I finally got an LT1, now the forged pistons for it are all the same price. i wanted a 383 stroker but if i can go bigger i will, on summit each piston is 16.99 for the .030, .040, and .060. Would an LT1 block be able to handle the .060? and im also curious as to what im in for with this whole wiring thing, i've always hated to work with wires but i wanted to challenge myself and I know this might be a hard thing for a 16/17 year old kid to do and being the 1st person in my family to work on cars this much but im very determined to to this swap.

Re: gettin my lt1 bored and stroked

Need to slow down a bit. You are getting in WAY over your head.

First of all, boring an engine does not increase displacement like most people think. The difference between a stock bore and .060 over is less than 6 cubic inches so we'll say 5 hp. The idea is to bore the engine the least amount possible and get a good round bore. Most machine shops will want you to wait to order your pistons after they machine the block.

Second, stroking will increase the displacement substantially. It will also require retuning of the ECM if you don't want to have any problems. I don't think you were planning on buying tuning equipment were you?

Third, the wiring will be the simplest part of the LT1 swap. You have the whole reverse cooling system to work with. It flows completely backwards from a regular small block.

Might want to start tweaking and learning the ropes with what you have in the car now then step up to the stroked LT1 on down the road.
