Either engine in a true street car built with good flowing aftermarket heads would be very hard to completely hook up , so to me it really boils down to how heavy your car is and it’s rear gearing in terms of what you build.
If your running a factory 4 speed then the added torque of a well built motor using just a 4.210” stroke no less a 4.250” stroke is going to eat up a factory 8.2” rear in no time!
I came up with a ratio for this in terms of added torque over a well built 400 and being able to beat on the car hard in terms of on the street usage.
Let me know what you folks think please.
The ratio goes like this , for every added 50 ft lbs of torque a given motor makes above a 3.750” stroke motor, you will spend a additional 3000 to 4000 Dollars to not bust up driveshaft, suspension and rear end parts when you beat on it over & over!
So in short the ratio is about 80 to 1.
