i want to convert my stock ls1 motor to a 383 stroker, if i were to do this would it be like a rebuilt engine with 0 miles on it. Also would this engine be more durable then a regular 350 ls1 engine? thanks for all replies and info

 

Would it be like a "new" engine with "0" miles on it? Yes. Would it be "as durable" as the original 350? Not quite.

When you're building the new motor, you would have to (or you should) replace things like all main bearings and rod bearings, timing chain, cam bearings, etc., and since you'd have to get new pistons (designed for use in a stroker motor), you would have to replace the rings as well, so essentially, the motor is brand new.

In terms of durability though, with a longer stroke comes increased load on the crank and the bottom end of the block, so for long-term durability, it may wear a little sooner than an original 350, but it's not going to be that bad that you have to be afraid to drive the car --- I had a 383 in my '81 Z28, and I (at 17-18 years old) abused the hell out of that car, and yet it ran mint, so it's not like you have to worry constantly, I just think that for a 383 compared to a 350, the 350 may outlast the 383 by a little bit.

If I were you, I would definitely go for it. I'm actually considering doing the same ONE DAY, once my motor has lots of miles on it, and once I can afford to (cause right now I'm f'ing broke!!!! ).

Let us all know what you decide to do and how it turns out.
