The difference between Marlin and Frank was the exhaust. You could hear Franks nice healthy burble while Marlins sounded like my Moms Volvo. Franks was just breathing easier.

Who knows. All I can say is that I DID NOT DO ONE THING in preperation for that race. NO plug changes (the plugs are the same and have never come out since Neal installed them years ago), NO carb adjustments, NO suspension mods, NOT EVEN a change to tire preasures. I think all the tires were set at 28lbs. I was leaving the line at about 1000-1200rpms and NO powershifting.

I agree with Charley, the biggest difference between the two cars is the exhaust. There are numerous other differences, ie; pistons, combustion chamber, etc... but the exhaust is the biggie.

I have a Gardner system on mine, the stock system not the deep tone version, so I have 2.25 inch pipes - crinkle bent, two resonators, single crossflow muffler with two-in two-out, and 2.0 inch tailpipes. Neal had installed the pure stock allowable 2.5 inch mandrel bent system with flowmaster mufflers. Better breathing! I knew the differences, and also knew the cars would be close after Frankie put the 3.73's in the rear and took out Neal's 4.56's. It was a fun, close racing.

I have Pete's copo Nova setup in my carb, approx. 38-40 degrees of timeing all in by 2500 rpm, and 40 psi in the rears, 45psi in the fronts. I couldn't run my spring clamps because they were interfering with the frame rails, and the bolts had too much of a shoulder on them and therefore would not tighten up. My fault, I should have installed them before the day of the race! Better yet, I should have called Neal to have him make me set like he put on Frankies car! I would either bog or hop, frustrating, but... that's racing

BTW, the CR's are probably a lot closer than I originally thought after talking to Rob and Pete - again, my fault for using TRW's

Frankie was smart not to mess with Neal's setup! I believe Neal raced that car in the Hemmings race at Lebanon raceway last year, he said it was in the 13.80's - right on schedule!

Frank could also Improve his gas Mileage,by getting the proper gas cap.
