Grossi and the Big Block

My point is the system as it is, is antiquated.

It allows a combination to run at an unreasonable HP factor until (if) the factoring system catches up.

Yes, I'll credit someone to choose something new, but the factor needs to be reasonable and with today's technology, that is not difficult to achieve.

In the meantime, it makes the tried and true (and in many cases overfactored) combinations un-competitive.

The real problem, as I see it, is that there are some combos that are classified wrong. They will run with an enormous amount of weight and still run 1.3 or more under. The tech people should be aware of somebody running real fast then being way over at the scales. It is sandbagging to save their bogus combo. If they get hit, they will just remove some weight and go for it again. The combo can be milked for years like this.

Running overweight is an additional problem of engines being under-factored.

It's always been difficult to understand why NHRA tech doesn't take this into consideration when re-factoring a combo. After all, they record weights every time the car goes over the scales, so why isn't this included in the re-factoring?

This is another reason why engine combinations, especially new ones should be properly appraised for the correct HP factor before being approved for use.

The current factors for a couple of these combos are out by approximately 30hp!

FJ,

I heard there was a HP review on that 1975 454 and they took HP off due to the smaller 220 ccs where the 1974 454 had upwards of 250 intake ccs.

We found that pretty funny because our 455SDs are rated the same horsepower (325HP), dont have splayed valves, has less compression, and our intake runners are 188ccs.

I would say there are tons of potential in that BBC Combo, hats off to Frank for making the correct pick!
