are you using slicks or street tires? 2800 - 4200 stall.Im guessing your shift rpm around 6200? If you use a higher stall and street tires the car will be difficult to hook up.If you are using slicks the 3.55 gear ratio is not much for a hard launch.

hey Vinnie .thanx for the response the car currently has 8.5" street tires but gonna have either drag radials or slicks when I take it to the track about the same width maybe a little wider.just don't want it to be a total PITA to drive on small cruises or around town.what effect will a heavy car and the good torque the motor makes have on where the converter flashes at ?

That engine is gonna spin the tires every time you carpet the gas.I used a 3800 stall on a street 454 and it pulled away smoothly at part throttle,not that I used light throttle often,it weighed 3600 pounds plus after being lightened and not me in it. My previous auto 67 Camaro had a 4800 stall converter but it had 5.57 gears and it would break the tires loose anytime I passed 1/2 throttle.It weighed 3360 or 3380,forget,and it didnt feel like it was slipping either except when just off idle.

If you race a lot you will use a race converter and race gear ratio.If you race just for fun and drive the car a lot then 3,000 is plenty.

yea I agree Vinnie its gonna be rough to find traction on the street with this motor .I am currently running a 406 sbc that shreds the belts off now from a dead stop its making 425 HP and 525 ft lbs but got a real good deal on the 421 .its a 4.155 bore +3.875 stroke .just have to assemble new topend on it . dart 215's ironeagle heads and vic jr. intake .do u think there is any level of accuracy in trying to determine piston to deck height with a large metal framing square and a feelers gauge as opposed to a dial indicator.

thanx for taking the time to answer my questions Vinnie probably gonna run a tci 3000 and also I have a set of 411 rear gears that would help out the cause at the track.they are a lot of fun to run on the street but the fuel mileage is terrible .

Hey jtz...FYI, before you buy look at www.yellowbullet.com and do a search for...freakshow converters. It will give you about 15 pages worth of very positive comments on this guy's T/C. His name is Michael Reeves and he is the owner and builder of all kinds of T/C from diesels to all out race car stuff. He used to build all the T/C for Art Carr/******* in Abilene, Tx. before they went belly up. He opened his own shop now and he's going to build one for me when I'm ready, he really knows his chit and he's VERY reasonable.....(325) 701- 7830

X2.. Yellow Bullet can be a good source for info.. They can be pretty harsh over there.. But the guys over there actually build the stuff and have actual experience instead of the book worms.
