Hey guys thanks for all the help.
I think im just gonna leave my 70 as a cruiser because thats a lil more than i want to spend on this car right now because most of my funds are going to my 69 nova big block car plus i would like to leave it original because it matching #'s, low miles ,one owner and i have all the original paper work from the dealer(dealer invoice,preorder form,manual protecto plate,ect.).I get ragged cuz its a 4door 6 banger but hey i luv that car.
I think im going to just run a y pipe with some dual flow masters for now and leave it at that for a while.
thanks guys
