I'm just about ready to drop a 383 into my 87 Camaro but I want a 2500 to 2800 stall converter before I begin. This will be mostly street driven, but not our primary wheels.

In checking numerous web site catalogs I see where they offer both Lock Up and Non-Lock Up converters for the 700 R4.

(My ignorance is showing but)Is there any reason I would even consider a Non-Lock Up? Just for a better understanding why would anyone, with a 700 R4?

I will be eliminating most, if not all the ECM and computer controls. Is conveter lock-up controlled from within the Trany or some external electronic wizardry?

Thanks.

If you have a choice, the lockup is a very nice feature to have on the street, especially with a high stall convertor. The only reason not to have it is the lower cost of a non-lockup convertor, but you'll eat up the savings with reduced fuel economy over time.

The lockup is controlled by the computer providing a ground path to the lockup solenoid (although the internal fluid circuitry won't allow lockup in 1st). There is also a switch on the brake pedal that interupts power to the solenoid when the brake is depressed. If you are eliminating the ECM, then get a lockup kit that is available from either Summit or Jegs.
