Getting above 950 wheel on stock 378 cubes without a bigger cam and ported heads probably isn’t going to happen unless you exceed 24-25 psi of boost which is gonna take a pretty decent piston and bottom end combination. But it doesn’t take 950+ wheel to get into the nines but it will take suspension work and hooking up 850 will do it. I ran a nine second pass only one time, 9.998 at 134 and that was around 850 wheel with a 298 210 143 1.00 Tranzilla (which I’ve since busted) and only one time, on a 315 50 17 inch MT StreetR and superb track prep, it was all made in the first 330 feet of the track. I’m just shy of 950 wheel now at a little bit over 21 psi of boost and I have a different ratio transmission now because I broke my 298 and went with a 266 9310 unit because I see more street duty than track duty but I plan on hitting the track again this spring and hopefully get a few more nine second passes in and at least one on video this time. But my real intention anymore is roll racing because quarter mile racing with a stick is just bust this bust that bust that again and constantly working on the car and it gets tiring after a while in more ways than one. It took a lot to get where this car is at in the video below.
