While motor's out.... Do torque converter???
I've never really thought about swapping out my torque converter, until I pulled the engine out....... Now it's just sitting there...
Basically stock '88 coupe, planning on a basically stock engine rebuild: Keeping the stock TPI system, maybe a bit of a cam upgrade, roller rockers, etc. Probably will go with a dual exhaust system, sans cats. The converter in the car is the rebuilt one that the trans shop installed when the transmission was overhauled about a year-and-a-half ago. Would I get a big SOTP gain by going with an aftermarket converter? I don't race my car, but I'm always looking gains where I can get them.
I also have an LS1 Camaro (six speed, though) and I know the LS1 auto guys swear by converter swaps. How much benefit would I get on my low-revving L98, with 3.07's? How much money would I have to spend?
Thanks,
Jason

I had Grant Transmissions install a 2,000rpm TC (stock was only 1,500rpm) when he did my tranny rebuild along with a shift kit and love the results.
This combo resulted in a drop of 0.3sec off my ET.
I would strongly recommend such a TC for mainly street application on street tires. Much higher will be very hard to hook up on launch.
Cost was about $225 for the TC.
