Torque converter ?\'s

I have searched and not found any answers. I have 72 K5, crate 350,th350,np205,4:56 gears, arb lockers, I'm considering putting a higher stall converter in it, what stall should I use? It's mostly a daily driver and about 5-10 times a year 4wheeler(mountains and rocks). Thanks in advance.

Re: Torque converter ?\'s

The most important issues are
Does this truck have a new cam, if so, what RPM range

How much does the truck weigh

Will your truck really benifit from a higher stall?
I would call a company like T.C.I. and talk to them.

it's just a stock crate engine, I don't know all the specs on it. I have no idea how much my blazer weighs, I would have to find these things out

If it's just a stock cam and set for low rpm torque, Putting a converter in is going to be a waste. If a bigger cam is installed, say like something that makes power from 1,500 rpm up, Then you would want a higher stall converter so when you pull away from a stop, The engine will flash up to an rpm which is in the new power range.

Ok, my problem is that I can have my front tires up against a rock and I have to put the pedal to the floor and it will take like 5-10 seconds to build up enough power to roll up onto it. What will give me more power for this situation?

does your truck just sit there and grunt then it finnally goes? What kinnda gears are you running with what size tires? ALSO how many miles are on your truck?

running 4.56 gears with what size tires??

Re: Torque converter ?\'s

yes, it grunts, sits, then finally goes. 35" tires, 4:56 gears, 3000 miles on crate 350. 115k on truck, 15k on rebuilt th350.

Re: Torque converter ?\'s

do you have a tach in the truck?
I think you would be better off doing a little work to the engine to INCREASE torque, before you get a converter.
It sounds like you just don't have the power needed. can you put a cam in it?

Re: Torque converter ?\'s

yes I have a tach in it, I can put a cam in it but I just didn't want to mess with the engine because I think it will void my warranty, but I don't know if there is any other way of solving this problem short of putting a manual trans. in.

Re: Torque converter ?\'s

well, If a engine is short on torque, there is only one way to fix it. If you think a higher stall converter is going to help, I think your wrong. The higher the stall, the more converter slippage. You will loose some torque. Everything I can think of is going to require you to do something with engine. Or regear axels for more torque multiplication.

Or swap in a stick.

By chance, do you think that maybe the trans itself is slipping?? how does the fluid look their??

Re: Torque converter ?\'s

It could be slipping I don't know for sure. I think ultimatly I'm going to have to put a sm465 in it, or modify the engine, until then I just get to deal with this issue. Thanks for all your suggestions.
