I like the car, here's my Plymouth version.....

I'd say those are great times for your combo. I just took my 452" B motor out for the first time a week ago, and went 12.40. My combo has more cam, bigger headers with 3" dumps, and 3.91's, in a lighter car, You have more cubes, and more carb, Im running OTB Stealths, but you're right where I hope to be! Great build! Nice car!
BTW: what are you carrying sandbags in the trunk? My Plymouth weighs in at 3760 with me in it. You've got an RB, but that seems heavy (???).

Cool car, but there's definitely more in it......Personaly, I'd put a better/looser converter in it.......I've got LOTS of customer's cars running around with 3.55 gears and 4,500 to 5,000 stall converters that run in the 10's.......

For comparison, this car's went 10.70's @ 124 the first and only time out at 3,500LBS with 3.55's, a STOCK stroke 440, OOTB Edelbrock heads, 850 Demon, big tube headers, and a cam similar to yours.......



Another customer's '64 Plymouth weighs 3,870LBS and runs 10.70's @ 124 also with 4.10's and 30" tires.........Another STOCK stroke, pump gas 440 with Indy -1's, mild roller, and 5,500 converter.......

I think ur times are pretty darn good. My car weighs #3600 and i ran 11.47 @117 and i got 3.91's with a 3800 stall. My 74 cuda has a 440 with Indy Ez heads,a hughes solid cam, an 850 Demon carb, 3' exhaust and all stock suspension. I think a better stall and gears will make a world of difference. I'd say 11.40-50's pretty easy.

Can someone maybe give a recommendation on a converter company to call? I've heard good things about the 9.5" Dynamic and PTC for efficiency and a nice flash stall. If a could knock down a 11.5xx on the 3.55's that woul dbe awesome.

Jeff,
Come grab my PTC 9" 4400 flash and try it out for free, before you buy something!

I think your car runs and looks great! I would do the stuff already mentioned and have fun with it. I personally shoot for a trap RPM that is 300 RPM over your best shift point. My current car shifts at 6600 and traps at 6900.
I also prefer ATI converters, I've had the best luck with them in a street/strip car.

Leaving harder in an automatic car just means more RPM.I usually brake torque to 2500 and just floor it on the last yellow.
