Thank you guys. What would I have to weigh with that 300" motor and an automatic in SS/EM and SS/FM?

Not sure how the percentage for the automatic works when it says 11.50-12.49 ect.. Do you go off of 11.50?

Based on 300 CID:

SS/EMA: 3277.5 lbs
SS/FMA: 3562.5 lbs

May be a good idea to do some calculations to make sure your combo would go far enough under the SS/EM 10.00 06.50 index before undertaking the project. Are the Dart/Buick heads up to the task structurally?

With a 286 dart Buick we've ran 5.85 1/8th at 120, and low 9's at 148 in the quarter in SS/DM, so yes, they can run under. Not near as quick as the new 10 degree Chevy stuff, but still respectable. We pulled 719 hp on the dyno. All with just a single disc McCleod soft loc.

on a pounds per cu inch with the Buick heads you are giving an equally classed car with Chevy heads a big HP advantage--just saying--- however the Buicks always seemed to work better at higher temp and higher altitude tracks---FED 387

Don't discourage the guy. If he's got a small inch motor, he should do okay with the Buick stuff. Harper used to be the man with those head and I know that Nickens did a bunch of small inch comp motors using them. I know that those heads are dinosaurs by today's standards, but depending on the class he may never have to deal with a heads up race.

What kills me is that you can pick up a used SB2 or wedge comp motor with all the best parts that makes killer power for about 25 grand. Now that's discouraging.

not trying to discourage anybody just making a statement of facts---also unless I misread the rule book SS/EM is 11.5 lb p/ci so 300 is 3450 pounds min & SS/FM is 12.5 lb p/ci 3750 pounds min--- for safety sake claim 301/302 inches because of scale differences so ya gotta put another 10 pounds in the car won't make much difference in ET but you won't come up light at the scales--- FED 387
