The engine was built to I'd say like 99% of the max allowed. Too much time and money to go any further on the engine. Besides, I think it's fine and I knew that when it was built. I just have detail items left there (better chrome valve covers, better chrome air cleaner lid, things like that). I do have some suspension things to do, such as replacing the last two rear rubber bushings with polygraphite. I do need to drop the tank, clean or replace, and replace the sending unit as I've been clogging fuel filters lately. Otherwise, lots of cosmetic stuff. Although most of it will have to wait until my W-31 is ready for the Pure Stock Drags as I need to have at least one car eligible to participate.
