I am posting this on the C5 forum as I own an '02, but it applies to all Corvettes that have computers, be they power train, ABS, Body, etc. Please remember when disconnecting and especially when reconnecting the battery to always disconnect the negative first and reconnect it last. This may...

I could be wrong, but I believe the 1965 250hp, 327 Corvette engine used 461 heads with 1.94 intake valves. I do not have a quick reference to check on this, but I swear I read it once upon a time. Mike

I could hardly believe it. I think I heard one of the commentators state the last time the track was last repaved was 1978 and is scheduled to be done again later this year. Should have been a couple of years ago. I guess it was more important for the France family to build their empire and...

I would bet it came from an early S-10/ S-15 with the 2.8 V6. The earlier versions used a long 12" long straight shifter handle, that screwed onto a short stub from the Tranny. These transmissions are not the "World Class" versions. Mike

And Mikey is right, it could be nothing more than the secondary air valve spring tension. Your rebuild kit instructions tell you how much wind up to put on the spring. And the secondary air valves are locked out as long as the choke is closed. This would explain the problem after warm up...

First, the little black piece of foam was to go under the secondary metering rod wells, in the throttle plate of the carb. If you took the throttle plate off you would see a identically shaped depression in the middle of the throttle plate where it is intended for the foam to be placed. This...

My '80 L-82 is the same, Corporate Blue block, black valve covers, aluminum intake. The car has 50k miles and other than replacement of the valve cover gaskets, has never been touched. Now my '75 L-82 was orange. Mike

Also check the float. Q-Jet floats are notorious for breaking down and absorbing gas. Lets fuel overflow the bowl. Every time I rebuild a Q-Jet I replace the float automatically. Mike

I think this all got started with GM began change from each name car having their own full range of engines to a corporate engine structure. This started in '77 or so when they started putting Chevrolet engines in Pontiacs, Oldsmobile in Buicks and Cadillacs, etc. And each line of GM engines...

When the '80 Vette was introduced, I read in one of the car magazines that the valve sizes in the L-82 were reduced to 1.94/1.5, even though the hp was increased. I have also seen the same information posted on the NCRS Technical Discussion board along with the possibiltiy that the late L-82's...

My problem with Dex Cool is that it is more maintenance intensive and less forgiving than the old green Ethylene Glycol. Yes, it may have some advantages over the green glycol (Dex Cool is still ethylene glycol), but unless properly and constantly maintained, it WILL create problems. Some of...

Junk, The last time I had to reset the drive cycle monitors it took about 100 miles of driving. I initially tried using the GM procedure to reset the drive cycle, but had a hard time following in on the densely traveled public roads in this part of the state. So I drove it for two days and...

C4C5, About disconnecting the negative cable, doesn't this mean you have to re-establish the drive cycle each and every time you reconnect the battery. Which would also mean that in states like NC that use the OBD II check for vehicle inspection you need to drive the car for a few days prior to...

Highly doubt if it is the clutch bearings as they are in operation all of the time, whether the compressor is engaged or not. Either the belt (which can be checked with a bar of soap) or internal compressor problems. Mike

Recently trouble shot a similar problem with an '80. Turned out to be the electronic delay timer (a power transister had burnt out) that shuts the lights off 30 seconds or so after you exit the car. Now all of mine lights worked via the dimmer switch, but nothing worked when you opened either...
