Is it wrong...

By the way, the picture is misleading. The C4 is actually smaller than the C3! The red one is pulled up a little farther up.

The Best of Corvette for Corvette Enthusiasts




My 3rd ex-wife (
) had an '87, which I'll call an early C4. The early C4's had a lot of electrical problems. The VATS system was very complex and hardly any voltage got to the starter relay, by the time it made it out. The TPI intake was a bastard to take apart, it was all Torx bolts and you had better clean out the hole on each Torx head, or you'll strip it.Late C4's. Not nearly as much electrical, but loose door panels are a common complaint (including mine), the power brake booster is a common replacement and very much a PITA. But other than that, not a lot goes wrong. The LT1 is a pretty stout engine and the 4L60E transmission is nearly bulletproof.
Here is the intake manifold for the TPI Corvette, when I removed it off've the '87. Believe me, I took, lots and lots of photos, because I had to remove all that stuff to get it hot tanked at the engine shop! The air and water inlet temp sensors, were the same size and thread!





When it was done, started right up, passed smog and still running five years later. That was my first top end, I ever did, by myself.

I've bought nice early C4's in the $5k range and driveable but rough bubble back C3's in the $4k range. I traded my beat up '95 Jaguar XJS vert for this '86 daily beater with 75k last year and am happy to have a decent little C4 again.
With that said....I'm also blessed to be back in the C3 club and it's getting most of my attention right now.
