I am currently working on motor and tranny setup. I need a few opinions on the final setup mainly converter stall and final compression ratio. This will be a street car raced a couple of times a year. Motor: 70 455 .030 over KB forged pistons 10:1 with valve reliefs Balanced, shot peened rods with ARP bolts Studs for mains and heads 71 heads stage 1, mild port job, polished chambers TA 1 7/8 long headers Old style SP manifold 800 q-jet will be sent to John Osborne TA roller rockers 1:55 intake 1:65 exhaust TA 413 cam Modified GN 200r4 with 3:73 rear gears Zero deck the block (or as close as we can get) I am thinking of 2800 stall converter and about 10:3 compression ratio. We can get 94 octane at the pump here in MI. Anyone see any potential problems here. I need to tell the guy doing my heads what cc to run. Any comments are welcome.
Sounds very similar to the one I just did. Some things I had ordered at the shop: Unshrouded the valves Oiling mods described here: http://www.buickperformance.com/oilflow.htm Mainly street driven I think you'll like that stall just fine with a 3.73 rear.
