Well his car is in pieces right now and he's having his engine built but we should get it back in a month or two. He's running it through a Turbo 400 (which we already had rebuilt and have at the house). But a stock 1969 GS 400 runs low 15s. I expect with the cam, tires, tranny, posi, carb, etc. that he'll run 13s. That should be doable with my engine and tranny setup.
Just make sure he's not stroking the 400 into a 455+ CI.
Very easy thing to do,like Pontiacs & Olds, (Pontiac 326),350,400 455's all look the same dimensions on the outside & can easily be stroked & not look any different on the outside,not saying your dad is doing that ,but,, just sayin.
