All hail the BBC...

Here's a forum where we can talk the good ol' Rat, the King of the Track.

While the SBC has the reputation of being the most hot rodded engine, at the 1/4 mile the Rat really shines. At Bandimere Raceway, they noted recently that around half of the cars that race there have a Chevy engine, and over half of those are BBC's. Since the vast majority of those racing there are amateurs who need to watch pennies, that's a significant statistic.

Personally, I've got the baby of the family - 1966 396 of 325 horse variety, minor mods such as .030" over rebuild, forged TRW pistons, stock closed chamber heads treated to home porting and polishing, 2.06/1.72" valves, around 10:1 CR, General Kenetics 270 hydraulic flat tappet cam, Comp Magnum roller tip rockers, Weiand Action+ dual plane intake, Holley double pumper with 750 CFM Proform mainbody, HEI large cap distributor with Accel box, Hedman hedders intended for the Impala chassis the engine/trans came out of. I've never had it dyno'd, but gross crank HP estimate is in the 400 sea level range. I'd like to get a Comp solid cam and RPM Air Gap type intake sometime in the near future to up the grunt a little. Grunt is the word since it's pushing around 3850 pounds down the track. But, it doesn't complain.

Looking forward to sharing info about our fav rodent!

Im am personally a big fan of the new small blocks with big block displacement. The SBC 454 and the new LS7 427. I mean you get all the displacement without the weight what could be better?
Ever since ive heard my neighbors 1970 LS6 454 running through the sidepipes on tha vette ive been a big block guy. Yah your right about being able to make the extra power on the huge engines to overcome the weight. I never thought of it like that.
Hey guys back when I bought the 69 I became a big fan of the Pontiac IBC because whats better than putting a 455 right in the place of a 350 with no moddification needed and nobody knowing the difference, EVEN WHEN THERE STARING INTO THE ENGINE BAY! BWAHAHAHAHAHA! Im even leaving the stock 350 emblems on it! :devil: :lol: :devil:
