Melonized Gear for Small Cap Distributor

Oops. Sorry, Carl Johansson.

The Melonized distributor gear (#10456413) for the OEM Coil-in-Cap
L98 TPI w/ roller cam turns out to have the wrong ID for use with the
External Coil small cap dist used for L98 TPI w/ roller cam in f-body apps.

Can someone confirm that #10495062 is the correct Melonized gear
for the small cap dist w/ roller cam.

Thanks,
Ken R.

Thanks for asking that question.

Carl has a #10456413 now and the ID is too large for the f-body shaft.
I've used this p/n on an OEM '89 y-body dist.

#10495062 comes from "Tuned Port Injection" by Frank 'Choco' Munday, ©1995.
However, the number is coming up NLA at an online source.

RockA shows #19052845 for late f-bodies. Here's a typical ex

Distributor Drive Gear
1989 CHEVROLET CAMARO 5.7L 350cid V8 MFI (8) :
1989 PONTIAC FIREBIRD TRANS AM GTA 5.7L 350cid V8 MFI (8) :

ACDELCO Part # 19052845 {replaces 10469459 discontinued}

Can anyone comment?

I used the same 413 gear on the HEI distributor on my 86 Vette and also just used the same one on the oil pump drive in my newly built 96 LT1.

I don't have any experience with the 'F' body distributors, so I can't help with that.

You may be able to find out which one works on the 'F' body by logging onto Thirdgen.org or Camaroz28.com boards. Someone there may know.

I was trying to sign in again at 3G earlier but the site has been slow
and I wasn't successful.

I just logged onto the thirdgen site. Took about 30 seconds to reach the Message Boards.

When you have time, give it another shot.
