lets play the number game....again - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Picked up my 350 yesterday, now it is time to tace the origins of it. Can y'all hook me up? I still have absolutly no luck with this crap. I remember some one told me to call some one up, but I can't remember whom to call, nor do I have a number.

On the pad up front on the passenger side... 1M0528 And directly under that one is 6VP
Then on the bellhousing, hecho en Mexico...I know what that means... then under that 10066036
I know it is a 4 bolt main, newer (painted black, passenger dipstick) casting, Pretty sure it is a 350...I don't think anything else came in 4 bolt in the later engines...or was there a 4 bolt 305?

The heads, are also hecho en Mexico...scalloped lower edge, so I know they are a light weight casting...the intake looks pretty friggen huge, and I was told it was 2.02...but they may well be 1.94's...my eyes haven't been calibrated lately.

The head number was hard to make out....969...968....or 369. I think the last one is correct, but I am not 100% sure.
Anyone have anything for me?

I'm going to put new rod/main bearings, hone it out, new rings a good cleaning....debating on a cam or not....trying to go low buck here, and it just isn't adding up to low buck. The bore has absolutly no ridge in it at all.

Longhorn Man · 09-20-2004, 09:54 PM

did I list a date code there by chance...or is there not going to be one?

dubie · 09-20-2004, 09:55 PM

10054727...350...86-up...2 or 4...one piece rear seal, some "Made in Canada"
10066036...350...........2 or 4...Target Master/Goodwrench crate motor, 2-piece rear
seal, "Hecho en Mexico"
10066038...350.....92....4...Goodwrench crate motor, 2-piece rear
seal, "Hecho en Mexico"

If it follows sequence, looks to be an 86 and up

Sweet...you guys rock.
i had forgotten that link...mortec is easier to use than nasty z28...but without the list of andy's favorites, I am lost.
How about the heads, any luck with them? Are they decent, best of the worst, worst of the worst?

dubie · 09-20-2004, 10:09 PM

Longhorn Man · 09-20-2004, 10:12 PM

The heads, are also hecho en Mexico...scalloped lower edge, so I know they are a light weight casting...the intake looks pretty friggen huge, and I was told it was 2.02...but they may well be 1.94's...my eyes haven't been calibrated lately.
