Me personally ... I was thinking of a 408 LQ4/9 build with L92/LS3 heads with a TVS2300 blower on top. Just wondering if it would need to run some thicker head gaskets or work the combustion chambers over to drop the compression ratio down to about 9.0-9.1:1. With the right cam, should be in the 800fwhp range for around $10-11k.
