Re: Question about torque convertors?

We need to more about your engine mods, cam? heads? intake? carb? Stock stall if I remember is 1800-2200 if I remember correctly.

Re: Question about torque convertors?

Also, most converter manufacturers can take your info and recommend a converter based on that.

If you contact Coan Converters (in Kokomo Indiana) they will ask for all the engine specs (displacement, cam, rear axle, anticipated usage, etc) and make whatever you want.

going into a longbed truck that was originally a 250 I-6/3OTT with a 12 bolt rear with 3.73 gears unsure if it has a posi or not,will mostly be driven daily with the occasional drag race along with some light duty hauling and towing,truck has heavy duty suspension,truck is a 2 wheel drive

so 2300-2700 stall speed is safe to go with taking into account my engine mods some of which may change im not sure yet on that one

Re: Question about torque convertors?

stock converter will be plenty good with the cam you have in there now . Too much stall will hurt you if you don,t need it .

thing is in orange crush-unknown gear ratio in rear,2wd,heavy half,31 10.50 tires on 15x8 rallys,stock suspension,longbed,no air,p/s and p/b and not much else weight or mod wise with the above mentioned 355 in it was a dog out of the hole.it would run high speeds ok but off the line was a joke.i think in ol red the engine with a tune up and maybe a few other mods will wake up nicely just trying to get an idea of the convertor i should go with and other mods i should make.
