Its funny you mentioned tires because i have been doing a lot of research on them the last few days. I may end up moving the springs in later. I have to replace the leaf springs eventually when I do I may move them inward depending on how much traction issues I have. I measured and about the widest I can go now is 235s I think if I can get the tuning down its gonna be a strong engine. I forgot to mention the rest of the combo. I got a neutral balance flywheel and a boss hog converter it's their street series it's like a 2200 stall I believe. And a 999 torqueflight with 3.73 rear gears
