Is the 1969 350/300HP combo that much worse and what parts are different than the 255 version? Point being if it's an intake manifold change and that is not as favorable maybe you can run that combo at the faster races typically,
I don't have a horse in that race anyway

The 350/300hp uses a different cylinder head. It uses the earlier style head (462, 186, 041 etc.). I'll have a better understanding of 255 vs 300hp after I get my 70 300hp motor together and in the car, hopefully within the upcoming months. One thing I can't seem to understand, as a 69, you can run the 255hp, 300hp, or 70 300hp intake on the car, but as a 70, you're only allowed the 70 intake. There's still a decent number of racers running the 67-68 295hp combo, which is the same as a 300hp except for the intake, but no one seems to be going as fast as the 255hp cars.
