Need help with old Chevy versus Mopar debate

Inspector71 said

Two brothers are locked in a debate. One says the Chevy 327 always beat the Mopar 340 (and even the 440). This has probably been done before but, are there any articles/documentation anyone can point me to with stock 327 4bbl versus stock 340 4bbl, A-Body to help settle this or at least allow the Mopar guy, who I naturally side with, hold his own? Thanks (yes, I looked on line and much of it was opinion and people on other forums trashing each other versus some numbers). Thanks

People like to use published Horsepower numbers that were inflated. NHRA factored, added HP, Mopar pretty heavy and defactored, subtracted HP, Chevrolet. NASCAR did the same. You can't have it both ways. When you cry that Mopar makes too much power, then crow that you won after they have been penalized. Look at Pro Stock in the 70's. Bob Glidden would wade through a sea of Chevies to win, first with Ford then with Mopar. The only rules were weight and cubic inch. As others have said above, there is a lot to racing. One of my favorite stories was of a 66 Chevy II w/365 HP 4 speed. He would tell you he was never beat. But talking with Mopar friends, A guy with a 68 or 69 340 Auto raced him and lost by two car lengths. After changing gears from 3.23 to 4.56, he beat him by 6 or 7 car lengths. The 340 and 727 just came alive! The Chevy II had a 4 speed and 4.10 gears. The 340 was stock. The small block Chevrolet is the lowest common denominator in racing. That is why Ford and Mopar where always factored, and the early Hemi's were outright banned. Chevrolet is not competitive without help. I won't even get into longevity. Bench Racing is not worth the time and effort. Tell them to Go out, get a car, and fix it up and drive it.
