OK everyone I have a question. I have all 3 vehicles available to do a LS swap into. The question is what one will be the best in your opinion and why?

Input from those that have done one or many are highly desirable!

My biggest question is, which one will be the easiest and need the least modification to the frame/car?

If we go with the Chevy II it will be a LQ9 with L92 heads, GMPP 88958675 intake (have not decided on EFI or carb) with a 100 shot and a power-glide. Basically the same config. for the 70 Camaro. The difference is weight and gear ratio in the rear end. (4.10 in the 70 4.56 in the 66). Either one would have a forged pistons & rods also. Basically looking for a mid 10 second car NA.

The C10 would be just a clean driver with a TH350 or maybe a A4.

So your input is greatly appreciated!

 

The Chevy II swap requires a lot of work to make it happen. An aftermarket front clip is only the start.
