I think you are taking a gamble on a used 40k motor with a trinity. Could it have been taken care of? Sure. But it also could have been driven hard for 40k miles with an aftermarket blower.
Let's say it all works out, great.. you save some money.

Thank you, yes once your making 1100-1200whp it gets very expensive. Lots of things like to break. This car is ready to go, no expenses spared and it would like you said cost 100k to build one.
