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!

What do you mean when you say temperamental?

I'm still somewhere between amateur and knowing something as far as real hands on experience is concerned motor building.

I've thrown together a couple mild small block Chevies from short block on up.

But I still see myself as needing some help when I build the 454 I've got laying in the garage.

Hail to the Rat! Have yet to see a big block car that didnt impress...wait a sec..

I once ran into a Pinto in a small town near where I live in FL. This was when my Elky wasnt a basket case and featured a very mild 350. The Pinto had a 429 in it out of a pickup, and featured headers cobbled into 2in cast iron pipe that they used plumbing old houses. A tired looking Holley double pumper sat on top of the stock cast intake.

I ran him from maybe 20 mph, and he had nothing, and I do mean nothing. My Elky ran a lo 15 at the time (one wheel peel) and I pulled busses on him.

Later in the week he ran at the Gainesville Raceway. I can't believe he got past tech. Maybe they just wanted to laugh at him. The car posted 16s.

The 454/TH400/Ford 9inch is a proven combo. I still need the rear end.
