This LT1 replacement short block is a great way to build up to a 500hp street lt1 engine for a reasonable price.

Our LT1 383 Competition short block is for the more serious LT1 guys that are running above 500hp and want that extra piece of mind.

We have made 720hp using this short block with our Stage 2 Ported LT1 heads, custom boost cam and 14 psi of boost.

You will be able to make Max Power with the larger 396ci, we have made a very street-able 550hp using this short block.
