Im restoring a 69 corvette,that has a 350/350 HP numbers matching motor with (C60). Factory air. Are these two pulleys correct for that application and year
*crankshaft pulley 71/4od GM#3850838BG
*Waterpump pulley 63/8 OD GM#3890419CT
The information in the new NCRS 68-69 Technical Information Manual & Judging Guide indicates those are the part numbers for the water pump and crankshaft pulleys on your 69 350/350.
They were both typically painted semi-gloss black.

Would be nice to see a few photos of the convertible you're restoring!!
It's always interesting to see what people are working on.

THanks for the info!!! SO the pulleys are correct for factory air car, will the factory AC belt work with thiose pulleys????
thanks again,
Hi R69,
I believe 350 engines when installed in cars with the a/c option use in addition to the 838 pulley, an added single groove pulley at the crankshaft location… pulley #3751232.

My Jan/69 L46 WP pulley is #3876846DJ .
I am second owner, had it since '73 , FWIW !
Another '69 L46 restorer here with pulley questions. I have a pulley alignment problem. I had my motor rebuilt by a shop so I don't know if they installed a thinner balancer. My problem is that the pulleys aren't lining up and the generator belt in the #1 track is going to rub the face of the power steering pump. My hard drive crashed and burned along with the 10000 pics I took during disassembly so I can't refer back to them to see if I had an alignment problem before the rebuild but I know the belt wasn't rubbing the power steering pump. I think my problem is with the crank pulley being a fraction of an inch too close to the block. Here's what I have:
Crank pulley 3911013BW (tracks 1 & 2) - this agrees with pg 331 of the AIM since I have a/c, I think this is the problem which is throwing off all three tracks
Crank front pulley (3rd track) 3751232BB - this agrees with pg 429 of the AIM since I have power steering
Water pump pulley 3876846 (tracks 1 & 2) - this agrees with pg 331 of the AIM since I have a/c
Water pump pulley 3883235 (track 3) - this agrees with pg 196 of the AIM
74 L82 with original engine, A/C, A.I.R. pump. Smog pump is original and water pump I bought NOS. When I tried to install correct belt from smog pump to water pump it was about 3" short. I bought NOS water pump. Could it have wrong pulley? What is diameter and part number of correct pulley. Appreciate any help.
Thanks
Went to work on car, could not find see number on pulley as it is installed but, I was able to find a matching belt only without the correct and number and date. Will address that at later date. I thank you for your reply and info. I will save it.
So I have correct water pump with a correct 6" pulley and correct belt from water pump to correct smog pump which also has a 6" pulley and still cannot make belt fit. I see on e-bay that they list water pumps with 6" and 7" pulleys, they didn't by any chance make a 5"? Was there more than 1 type mounting bracket for the smog pump. If I had hair I would be pulling it out now.
