Default Re: Any AA trucks running 55mph?

I just finished a complete restoration of my 29 CCAA. I cruise at 50 mph at 2000 rpm's. The engine is bored out .040, stock head, modern valve train with adjustable lifters, centrifugal advance dist. set at 8* to 28*, made my own intake for single barrel down draft Carter YA, exhaust headers, lightened fw, the transmission is mid 80's F150 with 41% OD. I shift into OD at 35 to 40 mph, the engine can handle it with no problem, the worn drive is 5.17:1. tires 6.50 x 20. I check all 8 wheels that came with the truck with a dial indicator, they range from .040 to .090 out of alignment measure just inside the lock ring groove. I installed a 56 f100 steering column. I drove with out tires balanced and then had them balanced, it made a difference. I think the front end vibration comes from the wheels and the crankshaft not having counter balance weights on it, I'm sure the truck will go much faster but I just don't need to.
carry on
