    Just picked up my truck. New everything all HD, plus thicker hardened sunshell, corvette survos, new rear main seal, and a new fly wheel. It had 3 broken teeth. Guess I need to replace the starter. They said for me to bring it back in 2 weeks for a check up.

    True, but if you're mainly driving around town where it's not locking up, or a lot of stop and go, it will be a problem.

    Changing the stall speed can help with acceleration. A "loose" converter changes the angles of the blades and allows a higher engine speed before it will start to move the car. This will help your engine reach max torque faster. An engine with a "big" cam will make max torque at higher RPM, requiring a higher stall to get the RPM's up faster. The bigger the cam, the higher stall required.
    You can check your stall speed by power braking. Hold the brake and apply the gas. The RPM you reach without moving is your stall speed. You have to have strong brakes though, if not, you will just spin the tires. If you apply gas slowly you should be able to get relatively accurate number.
    A converter will not have the same stall speed behind all engines. The more torque you make, the higher it will stall. That's why the change to a 4.3 converter works well with a V8. And why the V6 converter stalls at 2700 RPM behind my 454. And a stock converter is a lot less expensive than an aftermarket one.

    Yes, they did. That was quick. He showed me the old parts. Man the new sun shell is a lot thicker. The old one, almost did the same thing as the carrier did in my rear end. Broke the collar off that the out put shaft goes into. I am suprised about the flywheel. 3 broken teeth. All in different locations. All most across from each other. Found an old Orileys reciept in my folder of truck reciepts. I swapped out starters in 2007. Life time warranty. Guess I know what Im doing Saturday morning. Hell the only thing on the truck thats left that I havent replaced is the engine it self. The owner of the trans shop said everyone there really likes my truck. Also said it runs, but He didnt want to get on it to hard because its not his. Very happy with the service there. I had $3000 put away for this, and came in under $2900 with tax. Im very happy.

    That didn't work for me - it just started spinning the tires - stock drum brakes suck.:Big Laugh:

    On my data logs I can see it rev up to 2500 before my speedometer comes off 0. Before I got this trans and TC it was a lot slower off the line (900 RPM with stock TC). For my build, it's happier at 2500+ off the line and cruising. Another reason I went with the 4.11s from 3.42s

    Ok, driving to work this morning, I pushed it a little. It shifts very quick now. Almost hard. I love it. If you drive it easy, the shifts are quick but smooth. If you drive it hard, the shifts get harder.
