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. Last edited by SSGT Mustang; 10-24-2015 at 06:11 PM. |

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

Minus 5% for automatic. With a 300 inch engine, it's 3278 lbs for EM and 3563 lbs for FM.

I don't think the SB2 is legal in some modified classes. A great set of GM 15 degree heads still are reasonably priced, and a bit more competitive then the dart Buick. Can they run? Sure, but don't count on winning class at Indy with them. I love them for their valve train stability, and I wasn't trying to set the world on fire. But if you want to have fun, and just enjoy a cheaper modified engine, then go for it, but put it in D mod. You can't overcome that much weight.

For whatever reason they have it under weight in the frame section. Easily missed.

Since this thread is about SS/CS (or C/SM for older folks) my friend Pat Hennebery still races his 1968 Camaro old C/SM car in N.E.T.O. nostalgia racing circuit. Right now with a stock block and heads 327 , just dressed up for the old C/SM car with the intake, Holley 750, big tube headers, crank trigger, ect and a jerico 4 speed has gone 11.30's
Still has the 70's paint and decals, even a Lakewood roll bar! Back "in the day" he ran a 318 SBC with iron Modified heads, said he ran best of 10.59 He would go to Indy and there would be 25 cars entered in C/SM alone. He moved on to Competion Eliminator in the 80's , still has his C/EA Berretta plus a brand new Street Roadster to run either B or C/SR With that he has a few older Comp motors, Buick Dart head stuff. He was always looking for a Heads up type class, and ran in a IHRA class called Factory Modified, a "Junior Prostock" type class. They tried to get NHRA to carry it. I know if a heads up type of SS/CS class was around he would drop one of those motors in his Camaro, he even has headers for a Camaro with Buick/Dart heads. OK, maybe a heads up C/SM with only original rear wheel drive cars allowed? Keep the cost down? Here r some video of the Camaro Will Lamprecht I/SA 65 Impala in progress |
