Keep me posted if you do try them! Both our cars were so rough when we started that we really can do whatever we want to them without feeling badly


Some guy at work was asking about the car and if it was a 455 GS, I said no just a 350 Skylark. He asked if I was going to do a 455 swap I said no I just built a mild 355 inch for the car, and had a roll cage installed. He just kind of looked at me shook his head and said the 350 was a waste of money and the car would be too slow to need a roll cage.... 


Maybe I will have to take him for a ride since I am sure he will not even want to see the 350 under the flat hood. I might have to put some oil obsorbing sheets on the passenger side though LOL. he never asked if it was turbocharged LOL!

I would guess it was the extra weight causing more load against the engine and this causing the boost to come on harder and quicker. Turbos love resistance many people run faster in the quarter mile with a 2.73 gear than a 3.73 gear just due to more load against the turbochargers. You just might find your car pulls harder for the same reason with the taller tires if you do go with them. 


I know a guy at work who runs 9.1 @150 MPH in the quarter with his twin turbocharged Mustang. He started out with a 4.11 gear, went to a 3.55 and finally to a 3.00. Each time he went with less gear his 60 foot time got better, his 1/8th mile was faster, and his quarter mile time. He was running 130 MPH with the 4.11 gear so the 3.00 gear picked up HUGE for him. He said the car pulls better and makes more boost quicker. I think he is running about 20 PSi of boost, and I know he just got his cage re-done so he can run in the 8s.
