A little more input. I had a mid 90's LT1 Camaro, then went to a C5 Vette LS1. The LT1 had more low end torque, but the LS1 pulled stronger up high. If I was going through the trouble of an LS conversion, would go more cubes than LS1. World Products makes a crossbreed block that drops right in. Standard small block on the bottom, and all LS on top. Maybe something to look into.

While the carbed crate motor will be cheaper/easier to do the FI of an LS motor will be better able to handle whatever crap the gub'ment says we must use for fuel. Carbs were never meant to run on ethanol. I suppose it depends on how many miles you plan on driving your toy every year. /:\

Actually, some CF members have their carb tuned to run e85 to help w/ their high compression, but a LS would do better with variations in ethanol content with reg gas ranging from 5-10% currently with proposed increase to 20+%
