.....having a bit of a issue with mine (168000mi), had a good
corvette mechanic service mine and found some problems with
it, so I figure I will replace it this week.

.....QUESTION; ....so who do you believe....:huh: looked online
different websites after looking at Edelbrock's website came up
with a #3810, but when I go to an other websites they tell me
the #3810 if for 94-97 LT1....looking for a new ported stock
TB, I don't have enough mods to justify a larger TB....:laughing:

..... anyone want to throw in a brand and PN#.....:D

....when disassembled, the heater hoses that connect to those
sides of the TB and the coolant before I bought the vette had
pitted away some of the aluminum which has caused vacumm
leaks and coolant loss, we disconnected the hoses and re-sealed
the plate, but it has not cured the problem, he found that it is
the only issue at this time, the vette is running really strong
just I hate those little things.....:laughing:

Most of the new ones are 52mm at minimum. and between $250-300.

I'd check the want ads on some of the major vette and Firebird sites for used ones at a good price.

if you go with the BBk stay away from the 58MM. your stock intake shround doesn't fit without cutting it and honestly It's too big even for my 395 CI engine-- To set base idle the butterflys aren't even open.

I didn't want to deal with the aftermarket TB inlet mismatch, so I had my stock TB increased to 52mm. It's cost effective (appx $150) and even with the restrictive stock intake, I got a small but noticeable increase in the top end, with absolutely no bottom end loss in response. I used a guy by the name of Matt Blum; he has a machine shop in Cedar Rapids, Iowa. He not only ports it to 52mm, but adds bearings to the shaft, which the stock TB does not have. Real quality workmanship, and a great guy to work with.

I got mine from summit racing it comes with different linkage parts so it will fit different years it seems like a nice piece the only thing I didnt like is that you cannot change the top plate I have a nice corvette logo plate but the bolt pattern for the top plate is different

Yes, the faceplate was yet another reason that I wanted to stay with the stock TB. I used high quality black wrinkle paint, and then used a power sander on the raised "Tuned Port Injection"
lettering. Really looks nice; especially if you take the time to
polish up the TB itself.
