225 Max Performance Recipe?

Not necessarily. My 66 Valiant was built for $1500, including buying the car. First weekend out, we were running high 13's. I don't know of any stock 318 that will do that. Modified, yes. I now have about $2500 in the car, and have run 7.80's in the 1/8. Haven't run the 1/4 with this setup..

Op has a 73 Swinger, a tank compared to your car.How about put three overweight old guys in your 66 and try that again.

Or for a reality check, put that stock 318 into your 66, dress it up the same as your slanty, and try that.
And be sure to run apples to apples
