I'm thinking of getting the B & M holeshot 2400 for my 72 grabber c-4, rear end gears = 3.00 for now. Is there any hangups i should worry about? A friend of mine bought the torque master 2200 and his truck stalls and chokes out if he runs under 45, he was told to drive in lower gears untill over 45mph. then again, he has overdrive, i do not. What kind of increase will i get in terms of at the track and the weekend cruiser? info needed, thanks.
i have a hughes 2500, and i have never had it choke if i run under 45 mph. i had that in my car since i rebuilt the engine... and i had 2.79 gears. i now have 4.11 gears and i need a 3500 stall for my application. if you planning on upgrading later.. i would hold off until you know what you want to do, or buy a higher stall now and build into it and i see you are planning a 347 stroker.. you will need a high stall.. i would say at least a 3000
Sounds like your buddy has carb problems, not converter problems. Try Atlantic Torque Converters in Asheboro, NC. 336-626-4166. Ask for Mike. He can build you what stall you want and offers 1 free cut and clean (or re-stall) included with the purchase price. Last one I bought was priced at $.10 per RPM. I got a 3500 so it was $350. Quality piece with a forged front shell (not stamped), full braze fins and all roller bearing internals. I walked in to have my B&M cut and cleaned after my trans grenaded and walked out with a new one after he showed me the difference in internals. I have no affiliation with them. Just a happy customer. It's not often I get to say that. Cleaver
i have a 3000 stall in my c-4 with factory 279 gears and have no stall issues at all. i agree with cleaver. sounds like carb or fuel problems not stall. mine was built by j.w. performance converters. has run great now for 3 years. hopefully new gears and posi coming soon
Your friends truck has an AOD If I were a betting man. The reason it stalls and chokes is because once it goes into drive there is no stall it is a direct mechanical lockup.
thanks Robert.....thats why I posted overdrive in my above post.... my simple way of pointing out the main difference
thats great i may just ask for mike and let him know another maverick man recommended him... hahaha.... if i decide to get different gears, its going to be 3.55 thats about it. i wonder what my 60ft times will be with the 2400? and would a 3000 be better for my applications? i mean, it would be more on the street than on the track.
I would be careful of a stall converter that has an advertised stall speed close to what your cruising rpm range is.If you do alot of highway driving,heat could be an issue as the converter will be "stalling" all of the time .Might want to go with a 2000 stall OR(better for dragin')go to 3.55 or 3.80 gears.The 3.55's will put you around 2900-3000 at 60 mph(depending on tire size,mine were 225/70/14,26.5" tall)letting the converter tighten up a bit,therefore reducing heat .Just something to consider.
i would be driving it more on the street than at the track... its going to car shows and weekend cruiser kind've thing...my car now cruises at around 2500 at 60 mph. hmmmm... heat is definitely a factor, as i will drive this car out of state every now and again to car shows. I dont want the tranny to go anytime soon seeing as how i just got it rebuilt about 2 years ago and it's only had 2k miles on it since it's been sitting. does anyone know what the rpms would be with the 3.55 gears at say 60? i dont want to screw the car up... its my baby.
if you are going to be driving the car that much.....I wouldn't even mess with a stall converter. Just put in a standard converter.
The reason for a high stall converter is to get the car into the torque curve at take-off. Heat is only a problem if you are constantly accelerating with hard with rpm lower than your stall speed. Cruising is never going to build heat in your transmission if you have a good aftermarket cooler. If you cam is stock there is little to be gained by installing a high stall converter.
