Well it's looking like I will be doing one of these two options:
#1:
This L31
long block - $2200 (with core charge)
This
cam - $426
Valve springs - $246
Option #2:
Carolina Machine Engines rebuilt L98 "high torque version" long block with Vortec heads and LT1 B-body "police package" cam - $2000 (with core charge and upgraded valve springs for heads)
Both have Vortec heads which will require a different intake manifold to keep my TPI:
Vortec TPI Base - $480
This base says it requires Edelbrock
Hi-Flo runners - $450
Instead of spending $930 on new Edelbrock TPI conversion parts, I would probably just get a used Vortec HSR for around the same price.
I'm leaning towards the CME option because I will be able to keep the warranty even with the LT1 cam and Vortecs. I'll void the GM warranty when I swap the tiny L31 cam. Everything is still in planning stages though.
Thoughts?
