I just bought a 93 454 out of a 93 chevy ss pickup and want to put in a stroker kit. I am not gonna really race the hell outo it, I just want a nicly built big block. I have a couple of questions, how thick are the cylinder walls and is there a thickness issue or pro's n con's on going .060 over vice .030?

If it's going to be a street engine, I wouldn't bore it more than necessary to clean up the cylinders. If it were me and thinking of going .060, I would have the cylinders sonic tested. You just never know how much core shift a block has so it's better to be safe.

Generally speaking .060 is no problem on a big block, even .080 is not a big deal but as stated before, there isn't really a reason to go that big unless the cylinders are trashed. By the mid 90's GM had pretty much figured out how to cast a block that was in specs so spring for the sonic testing if it makes you feel good but it is probably not necessary.

If you aren't going to take it over 6000 RPM then just about any of the stroker kits out there will do, rods are the key to the whole situation, the better the rod, the longer it will last, also you want to pay attention to whether or not the kit will work with stock length rods. It starts to add cost if you have to find a specific rod length and piston combo. Rods that are +.150 or +.250 or +.400 are fairly common but the longer the rod the shorter the piston and that can limit your options sometimes.

Check out Competition Products, I have used their stuff before, they have kits to fit any budget and price range.

Good Luck
