why not ? its in great shape other wise he wouldn't be selling it. every one that hes sold parts to has been vary satisfied....Its cool though i was just trying to save you some money since your on a budget
His Trans Am is probably flat tappet. That's a no no. That's new cam and lifters for those. Yes it performed well. Great cam for low to mid power. It's not going to do much for you over 6k though, but most people don't rev that high anyway.
People on the Anything and Everything GT40 site seem to like the TF stage 1 with gt40 heads. Don't matter to me if I sell it or not, since I have a project car here still. It was supposed to go in that car with my old TF 170's, but then I sold them. Then I was going to do gt40's on the cheap with that cam in it.
