.. Those cars were known for terrible 9-11 MPG and sluggish performance with dished pistons and big 76cc chamber heads... nominal 8.5:1, but actually ~7.6:1 compression ratio. I'd definitely go stock type 4-eyebrow flat top pistons or even 2-eyebrow hypereutectic flat or minidome pistons such as KBs if they fit your budget to get power up throughout the RPM range and cruising MPG up near 17-20 MPG. That cam needs at least 9.5 and preferably 10.5-11.0 compression ratio to run STRONG, which is what you must have to win your race. Power should be 350-400 HP with that cam and Vortec heads depending on other final components used. Torque peak around 4000 RPMs, HP peak around 5500-5700 RPMs, shift at 6,000+ RPMs when racing. The factory RPM range suggested for that 214/224 cam is conservatively much lower because they don't know if you're putting it into a slug stock 7.6:1 engine, which most prolly are, yielding disappointing results. Borrow some short 275-50R-15 (or shorter) drag radials for the track. A 2-bbl. carb. would run fine but start noticably falling on its face at a low 3500 RPMs. Put a properly tuned vacuum secondary 750CFM carb. on it. 600 CFM carb.s usually come default tuned for 305" and slug 350" engines. You'll prolly need the 3000 stall converter to win your race.
