I have an '87 Z51 standard trans Vette. I am going to install a big block in it, with stand alone aftermarket EFI. I have the fans and overdrive handled without using the computer, and will be bypassing the ABS system. The only thing I want to keep is the digital dash. (Maybe). What do I...

Hey guys, sorry if this has been beat to death before.... I need to replace the rear wheel hub assemblies on my C4. I know I should buy the Timken hubs but at $110.00 each that is outside my budget at the moment. But then I don't want to buy Chinese junk for on the car either. Are there...

My brother has a '94 Z-28 Camaro with a Holley throttle body on it and he his going to sell the car. Can I make that throttle body fit on my 87 TPI Vette? I can do modifications if needed. If it can be made to fit, should I put mine on his car to sell, or save mine along with the other original...

1987 Corvette. I want to remove the doors. Is there a main disconnect connector somewhere for the mass of wires going into the doors? Thanks! vettebob

1987 Z-51 standard trans Vette I am presently using the factory dual exhaust with the catalytic converters gutted, and Flowmaster mufflers. I'm also running a 180 thermostat and a coolant sensor that turns the fans on at 180. Soon I would like to rebuild the engine with a moderate Comp Cams...

1987 Corvette. Been a mechanic for 40 years, but I am having trouble with this one. My Corvette will hold a 17 lb. radiator pressure test for hours without dropping even 1/2 lb. and not a drop of water leaks out anywhere. However, the car may run fine and hold water for weeks, and make long...

The A/C compressor just went out on my 1987 Corvette. My brother has had numerous problems with replacement compressors going bad in about a year on his Camaro and his Trans Am. I don't want to do this job twice, but my budget is limited. So, what compressor should I buy? Reman or new? What...

Hi, Time to repay a bit for all the help I have received from the forums about my 1987 Corvette!! My electric rear hatch would not open, and I priced a new solenoid at over 140 bucks. Ridiculous. So I decided to take it apart and see if I could fix it. This post assumes that you have good...

Hi guys, 1987 Corvette, 4 + 3 standard trans, cruise control inop. I have a factory manual with supplements on my Christmas list, but for now all I have are the Haynes and Clymer manuals. They are all but useless for electrical problems. I worked all afternoon trying to trouble shoot my...

Man, I hope somebody can help me with this.... I have been web/forum searching for hours and can't find it. Trying to get this '87 Vette ready for a trip asap. My books don't have the correct wiring diagram and I can't find it on the net. I want to convert my 4 + 3 to a manually switched...

Hi, My 1987 Vette has 255x50R16 tires on the back, and 245x50R16 on the front. Is that correct or should it have the same size on all four corners?? I need to buy tires, should I go with the 255's x 4? Thanks, vettebob

Hi, 87 Vette with the 4 + 3 trans. Anybody know how much fluid the overdrive takes when changing it? Also, the clear coat is about half gone on my (original) wheels. What is a good way to take the rest of it off without damaging the wheels?? Thanks! vettebob

Hi, Does anyone know what the gear ratio is in overdrive on the 4 + 3 setup? I am assuming it is 1:1 in four gear without the overdrive... vettebob

Hi, New Vette owner... I have a factory service manual ordered, in the meantime all I have to rely on are a Haynes and a Chilton manual. Neither one say a thing about wheel bearing service other than removal and re-installation. Are all the wheel bearings (front and rear) on the 1987...

I live in the desert southwest, and do not want my car running at 230 plus degrees. They can talk all they want about this being good for engine wear, but I am a mechanic with 40 years experience, and I'm not buying it. It is all for smog purposes, and besides, at 230 you only have a very small...

I have a 1987 Corvette and I am thinking of going through the engine. The car presently has no catalytic converters, and the stock mufflers, though I might change the mufflers too. The question is, which cam do you guys recommend? I would like to stay with the factory roller lifters, and I...

Hi, Just bought a 1987 Corvette and the owner had converted the A/C to R-134. I want to convert it back to R-12. I have gauges, vacuum pump, and access to R-12. Can anyone outline the process to convert this car back to the original R-12?? Please, I know there is a huge controversy about...
