    700R4 Information Thread

    Ugh. I've been going back and forth on whether or not to use an early valve body with mechanical lockup or make my own TCC lockup control for the 89 700r4 I'm about to build. It's going into a 600+ hp big block Camaro. Mainly street driven, with an occasional trip to the strip. I'm not really...

    700R4 Information Thread

    Not advisable, 10-4 My other trucks have 6l80s, so ill just keep the slide and rotor for the 700. Not 100% sure what year the 700 with the bad pump is. It's buried under some camaro parts at the moment. Thanks Nick!

    700R4 Information Thread

    Picked up a 2003 4l65e for parts. One of the transmissions I'm going to build is a first gen 700. I have the 716 drum from the 65e, and I want to press out the 300mm input shaft, and install the 298mm input shaft from the 700. Will the pump from the 65e work with this input shaft, or do I need...

    TH350 To a 700r4 transmission

    I've watched a couple of your youtube videos. They are top notch. Have you been through a Hughes transmission? I have a 74-1 that I'm going to rebuild. I think I'm going to be sad when I open it up and find a stock input drum and 4 pinion planetaries.

    700R4 Information Thread

    New question - 5 pinion planetaries, is the juice worth the squeeze? Gathering parts for a 700r4 that will go behind a 454 in my C20. Mild build, probably 500 ft/lbs at the crank. Strictly street driven. Pros - I think the torrington bearing vs flat washer is big step forward for reliability...

    What's your opinion on Alto Power Pack vs Borg Warner High Energy (with 7 frictions) in the 3-4 stack for a race application?

    Etch primer and sun baked 'surface rust'

    Skip the etching primer. Clean up the rust best you can, then treat it with Ospho. You can get a gallon of Ospho at most hardware stores for around $30.00. Ospho pickles clean steel, converts rust, and it does a really good job. After that, seal it up with an epoxy primer, then a sandable primer.

    Run the single springs, and get a set of rotator eliminators too

    1985 small block 350 won't start

    No. The well plug issue is only on Q-jets

    battery post mystery

    The US military had a problem with some missile guidance systems corroding and causing failures. They cleaned the troublesome connectors with Deoxit, and the problem went away. Allegedly.

    89 firebird to buy or not to buy

    My first thought too. Firebird daylight pic with headlights on means one or both doesn't close. Second thought: "Car has a short, but it's simple to fix" :happy175: Sure it is. Where's the short?

    Decent Paint Job

    This thing actually works better than it should. https://www.harborfreight.com/20-oz-professional-hte-compliant-gravity-feed-air-spray-gun-64824.html I personally think that spraying paint from a gun is easier than from a rattle can.

    Frankenstein 454 swap. Overheating at idle.

    looks like a gen 5 454 with some homemade accessory brackets. I would start with the water pump.

    BBC engine ID

    820's are good heads. Big ovals ports, and slightly smaller chamber than 781 & 049's.

    454 Oil Pan

    Good call on the repair. I can confirm that the engine has to be lifted several inches to get the pan off of a 2wd 454.
