Yes, Frank that 9.5 to 1 Olds 350 with ported big valve heads. Getting a custom cam similar to the cam you are running in your 403. The 70 will see the track some but it will be more of a cruiser and won't see the track when it is done. I also received the 10 DN Chrome 70 amp alternator. It had a tag proof of performance tag stating 51 amps at idle and 82 amps at cruise. That should be perfect for my dual electric fans and mildly upgraded stereo. The seat cover looks good, hopefully a nice fit, same with the package tray. The window sweeps fit Ok, redrilled the back screw hole, sat to high. The rear fit poorly and needed all but one hole redrilled and the chrome trimmed and some RTV on the back edge. I will put the 403 stroker with Procomp heads in the 88 along with a TH350 with high stall and a 9" with 3.89 gears. I have #6 heads milled with 2.05" intake valves and better springs but I think they would give perfect 9 to 1 compression with .028" head gaskets on a mid 70's Olds 350 and I will have a good performer cam lying around. Need to find one for a good back up, usually near free and in great shape. Try that with a sbc of that era, good luck. I think fiberglass parts and racing seats will be part of the plan. For now it will get an Olds 260, stock TH350 and 7.5" 3.42 open rear, kids can drive it.
