Sprag or spragless

#3600 pound car with 545 and a c6 with 4.10 gears. I am ready to put the motor in and order the converter and I ask , Sprag or no Sprag?

give Lenny a call @ UCC ...his website is in the side bar >>>>>>>>>

ps change your weight

x2 lenny is the man

600 pound car? It's just an engine with wheels?

Spragless IMO

3600lbs

If you can give a little more info it would help out. Engine specs, street driven or just raced. I would think a 10" if more toward street driving, a 9" if more race oriented. They would both utilize a sprag for performance and heat control. Whatever your driving preferences, one of these two configured for your combo would work great for you.

650 tq @4400 rpm and 650 hp @ 5800 rpm the motor has a 600 tq flat line from 3100 rpm till 6000 rpm. The cam is .726/.726 lift 296/296 @.050 du solid roller with a victor manifold and a 1050 dominator. 11/1 comp in a car that is going to be a bracket racer. I dont have a trans brake , but will add one soon. c6 4:10 gears with 28x10.5x15 slicks No spray just motor

I'd go with the sprag.

A 9" converter (S98) would work great in your application, especially with the weight and stroke. Not only will it be the quickest piece in the car, but very consistant. It can be built with either an X5 sprag assem. or a mechanical diode(both are one way mechanisms that allows the stator to run one to one with the turbine and pump after flash or torque multiplication). This converter uses an 8" stator that is very aggressive on the leave and the S98 core we use has a 5 qt. fluid capacity that ensures maximum lock up and heat control. Hope this helps as I tend to start getting long winded with all the variables involved in converter theory. Simply put, one size does not fit all.

Thanks for the kudo's and let us not forget that we have one of the best NOS guys around in Steve Johnson at Induction Solutions.

and the losing-est driver in mud racing history.

Im a legend!

Why do guys run a spragless?

because they keep breaking sprags.............have yet to join that club.
