Flexplate bolt pattern/torque converter question.

[American84K5]

I'm looking into upgrading my stock tq converter on the th350



I'm looking at this B&M 2400 stall converter and it says I need a small bolt pattern flexplate or dual pattern flexplate for installation.

My flex plate is from a 84 305 if that makes any difference

Thanks!

Why do you want to go with such a high stall? Factory is around 1450 and I went 200 rpm higher for my burb and it gets up and goes pretty good. Too high of stall and you are going to make all sorts of heat.

Well I'm still deciding, but I want something between a 2-2600 stall.



I just want some low end power and great all around performance.
Plus I might take it to the track every now and then

Check this place out, I got my torque converter from them.

So I figured I have a 14" dia flexplate with 168teeth

If you want this convertor for a truck you will be VERY UNHAPPY with any bottom end. Do you even understand what "stall" means? All of the 153 tooth flexplates use the small convertor pattern and the 168 tooth either have just the large convertor pattern or a dual pattern with both sizes.

Yes. and I went out and measured an think I have a 11.5 bolt pattern.

Don't know if its dual pattern or not.

Well goodluck.

I'm no mechanic, but I've replaced my tranny and TC a couple times in the last year or so. You may want to research your stall speed selection a little more. Talk to a pro about what your plans are with the truck. Over 2000rpm stall will probably be OK for road and mud use, but if you will be doing technical wheeling, rocks or moderate or tougher trails, that stall speed may be a bit high and take you out of your best torque and control range. Again, I'm no mechanic, just some thoughts! Good luck!

Truck probably won't be wheeled since there's absolutely nowhere around here for me to wheel and it doesn't rain so there's no mud.

So far I am VERY happy btw

If you have a stock 305 and it normally makes torque say from 1500 to 4500 and you put in a 2600 stall you will have lost some very usable power.

Decent converter for street use , it probably won't stall at 2400 rpm , unless your motor is a little more than mild .

Mine stalls at about 2500
