396 2bl combo

I also have intake - carb and even the air cleaner.

Billy, I've always convinced myself that one reason the wind is a bigger problem with slow cars is due to being on the track for a longer period of time.
I tried a 2 bl on a 220Hp stick car back in the day and it was 1.05 slower. I changed it over at the racetrack and changed it back after one run.

In 1972, I was testing our 61 Chevy, 2 bbl, PG, SS/X car at Ct Dragway.
It was running around the new minimum (14.80's ) I stuck on the WCFB from Joe S's 61 Vette, and picked up about a second . No one on hand ,including several S/S racers, even noticed!
Goes to show , some think all slow combos are bogus!

Of course on a 2bbl it is easier to activate the tilting mechanism with the throttle linkage. Don't forget to adjust the fuel mixture for WOT, not pit cruising!

Mark, did you happen to try the old flat washer trick between the 2 bbl and the intake. Bet Jimmy Parker can relate to those days....Not meaning he did it, but that he saw it.....Frank

No, not on that one, seeing it was a PG car.

I DO know ,you can remove three little parts from a 4GC carb and pick it up over a tenth..
or so I'm told. LOL

well, I hate to say it but I built that combo way back when stock rules meant stock. factory pistons ,presses pins ,stock lift, duration, and overlap stock valves,rods, I did use the cast crank,racing head service did the valve job but the valves were backcut when they showed up so I had to re cc the combution chambers. a RPM 7000 series cam dynamics cam with stock lifters ,valve springs were very low pressure 96lbs on seat 225 over the nose,stock trans was a t-400 no gear set then or aluminum was available then,and I used a Rossi 9" cortina convertor 4800 stall. @4705 racing wt. for Q/SA 14.35 index we went 14.17@84 mph 2 time out, the gear was wrong we started with a 5:57 but the engine needed more like a 586 or 614 it only finished @ 4600 but we shifted @6000 and it pulled good you have to mechanically overcome the over 2 tons of wt. The car was fun it would pull the wheels 3ft and once I raced jerry mcClanahans Q/SA which was running 13.80's at the time and thru first and 2nd gears our wagon went off and hid from jerrys car but plug high gear and he would drive around me. It was early in my racin career so I was pretty green and still learning but my partner didnt want to keep racing so the project was cut short of its full potential.I pulled the engine & trans and sold the car to tony Janes with posi and 557's still in it, It was a 1969 brookwood 6 passenger body. .....memories???..JUST MY2 CENTS

by the way the cool part about this whole deal was, we found the wagon at a upholstery shop in the back it was original 2 bbl 396 car no motor or trans but the owner still had the intake and carb (435)cfm 2bbl , we bought it for $75 cleaned the interior put a seat cover on the front seat and painted it refrigerator white like GRUMPY my idol at the time. THE GOOD OLD DAYS Hmmmmmmm JUST MY 2 CENTS
