LT1 with
Whipple Supercharger
Updated June 4/10
This the start of phase II
I am currently building a new engine capable of handling ~1000hp maybe? I won't
really get the chance to try this since I am shooting for something less 650-750
hp rear wheel.
I am going to use my new intake design with a Whipple 175ax supercharger.
The long block is being built by D,Sousa performance in Milton Ontario. This
engine is far from taxing his expertise in the performance world.
The build so far for the LT1 is as follows.
Phase II LT1 with Whipple 175AX
-Stock LT1 Block machine .030 over 4" bore
-3.48" Eagle 4340 crank = 355cuin.
