Default Re: O/SA questions

If you speak to anyone at NHRA HQ, you might want to ask them to fix the Classification Guide for the '75 Nova - no shipping weights are listed for that model, just a repeat of the lb.-per-HP/factor chart.

Good Luck with your project, but just remember that this is supposed to be "FUN", and when it stops being "FUN" we need to find something else to do!

This has been a dream of mine for a while but the fun part for me is the biggest part. I'm just new to all of this and some things get a little confusing for me with rules and trying to figure out how to make a car that weighs 3540 go 13.99 at our altitude with a 2bbl lol

NHRA also wants to see runs at a Divisional before they start making adjustments to HP.

Yeah, they probably should after the dilemma they caused with lowering the horsepower on the 302 2bl Fords.

The hp rating is one thing that confuses me. The 75 is rated higher than 77. Same motor but rated lower. How is this possible?
