Mopar Street Stock?????
Anybody, and I mean anybody running circle track is gonna tell you three things:1) You're an idiot for running a Mopar 2) you're gonna spend a fortune (but they'll be glad to take your money, build it like a Chevy, and then tell they told you so..) 3) You'll never get it to work, build a "metric" car. Which, by the way is an early 80's Monte Carlo, Grand Prix, Regal, or Cutlass.
How much circle track experience do you have?
Remember the GOLDEN RULE when building a Mopar: It's NOT a Chevrolet!!!
I see you already have a Olds Cutlass, well skin it with a Mirada, Cordoba, Imperial, Diplomat etc and drop in a small block. Remember, Mopars are torque makers, you don't hafta twist the puss out of it to hit its power band.
