part numbers/casting numbers for 1968 L36

[70CitrusZ]

Wondering if anyone can help with correct part numbers for some things I am looking for.
Looking for correct starter, alternator, & non smog exhaust manifolds part numbers so I can scour evilbay for items I need for my 427 Biscayne resto. My engine build date is Dec 23 67 if dates make a difference in part number used..
Thanks,
Mark

If your car has a manual transmission, the RH ex manifold was #3918862. LH was #3989310.
Auto trans RH #3914613. LH #3919862
There are a lot of alternators listed. You need to know what amperage yours was.
Starter number looks like 1107365.
Others here may have better info than this. This info is from a GM full sized Chev parts book, #761, dated 1976.
The numbers given are listed as superceded numbers, so should be original.

Hi John
Its a manual transmission.
Curious as to why the different numbers for exhaust manifolds based on transmission?
Also, my car would have just had the base alt, 37 amp probably. car had no power options at all.
Thanks for the input..Mark

[StriperSS]

Base alt. for yours was 42 amps.
42 Amp for a manual trans was #1100815
42 amp with TH trans was #1100795
service part # for both is 1100842

Mark, those numbers look to be supercessions of the original numbers. Colvins Chevrolet by the Numbers doesnt show the 3918862 at all and shows the 3989310 started in 1971. Of course there's always the possibility of misprints or Canadian production being different. I think you need to check it out a little more.

Most likely you will find you need 3916178 passenger side and 3914613 drivers side, but it pays to check further before spending the big bucks.

John, I posted the date and number of the parts book in case someone had previous information that was better than mine. I saved a lot of the parts books from when I was in GM parts, but didn't have the foresight to save a 'change-up' book which would have given original numbers.
The numbers that I gave seemed to be correct in that the new numbers had a note stating that pipe thread plugs needed to be put into them to make them right for 68.
I'll bow to your info.

I think that you will find that a superceding part number is a part from another application that will do the job but may not be correct. GM did a lot of that over the years to cut down on the parts warehouse inventories.

[StriperSS]

I agree. I didn't post the superceding numbers.

I ordered a 442 front emblem for my 68 442 in the mid 80's, and actually got a '4' that was correct for a 67 Corvette hood. http://www.yenko.net/ubbthreads/images/graemlins/smile.gif Someone thought that would work. http://www.yenko.net/ubbthreads/images/graemlins/smile.gif

hmm... I could have sworn I just replied to this, but here it goes again.
Arent 37 amp alternators the base alternator?
Thanks to all who offer up all the part numbers I need by the way...

[StriperSS]

According to the parts book, a 37 amp was for a 6 cyl. car. Base amp for a V8 was 42.

[YENKO DEUCE REGISTRY]

Parts books appear to be wrong, as both small blocks and big blocks came with 37 amp alt's.

[ORIGLS6]

My '68 427 Corvette had a 37 amp alternator too.

Hi Mark:
The manifolds would be 3916178 and 3914613 as the guys stated. Starter 1107365 and the alt 37A 1100693, the 42A was optional on the 67/68 fullsize 1100696.
take care
Joe

Thanks Joe and others..I will scan evilbay for these parts, I just slept on an alternator and lost it..doh..
Oh ya, I have a clutch fan I bought.. number ends in I think 770, what fan would my car/engine combo use, a clutch fan I assume..

[70CitrusZ]

Any body here have any Parts for 68 L36 manual trans car?
Mark

[68SSCamaro]

The correct alternator is 1100794 per Colvin.

I listed a 178 exhaust manifold without smog a few days ago in the For Sale section with early Dec 67 dates.

[70CitrusZ]

I've been checking there, I must have missed that I will look again.

[70CitrusZ]

Thanks but wrong date for me...

[68SSCamaro]

What dates are you looking for? I thought Dec 5 or 13 1967 were good dates for your engine.

[70CitrusZ]

Hi,
I don't know..are they?
I just thought from my engine build stamp of dec 23 1967,dec 5 or 13 would be too close to be installed..ie: 10 days after casting, but I don't know this to be fact.
My heads are cast sept/oct 67 and my intake is oct 67, so I just figured the exhaust manifolds should be similar, but maybe I'm wrong? I don't have my block nearby but I think it was Nov or Oct?.. If anyone else has any input That is why I posted this to start with, to see if the date ranges are correct on the parts I still require.
Mark.
