I got my model a and will be logging the changes done to make it into what I like. What I have is a stock top highboy on 32 rails, cycle front and widened rear fenders, gm 350 crate motor with 600 performer carb/ weiand 8004 manifold/ shorty block hugger headers, th 350 trans with possibly a stock converter, and a 7.5 ford live rear axle. I have no idea on the history of parts or build by previous owner. The brake system did not inspire confidence. Manual brakes, 1 1/8 master, no proportioning valve for disc/drum, no residual valves master cylinder under floor. Brakes were stiff, took to local shop and work properly now. my goal is to have a fun ride with enough power with decent gas mileage. Probably will never see a strip unless it was at a rod meet so not worried about et numbers. I have been reading a lot to figure out what my goal is. A low to midrange torque engine seems to fit my needs. I have not made any decision on transmission, man/auto standard/ od and what will fit without major modifications to floor and frame. The rear end will need to go, any type posi upgrade costs more than an 8.8 with a posi. So for the engine here is what I have come up with, your thoughts on where I am going wrong or right would be appreciated. vortec heads if good [pulling from Yukon now] if not summit 62cc aluminum 170 intake[sure they're trickflow], gm ls6 beehive springs, arp head bolt set, roller rockers 1.6 [I realize they're not really needed], lunati streetmaster cam & lifters 225@050/275 advertised 477 lift 1.5, k&n velocity stack air cleaner, mellings155 hv oil pump, I have almost no oil pressure at idle and 20 psi max. I will post my progress as I slowly proceed.
