Thread: Engine code deciphering

right now my engine is not working, and I have not been able to fix it. So I've been searching for a replacement, I think I've found one with low milage on it, just that when the owner sent me the engine numbers, well, I have not been able to find out any info on the net about the year of the engine. He told me it was either a 1996, or 97 or 98 ... my car is a 98 gtp and this motor is definately an gtp, cause it has the S/C on it.

The info he sent me is ... 60er bkz-aa 10bkz and b0216715

Any help would be appreciated.

Thanks

Chuck

right beside the part number it'll say "SERIES II" if its a series II or III.

Unfortunately every series II and up uses the same block.

Oh, well is that not sweet of GM ... was hoping there would be some info for a date on them numbers. '0'
Thanks for the reply Matt.

Well to be frank: the only thing that won't work is a series I.

My research says that GM went to series II in 1997 and series III in 04 ... so my fingers are crossed that it is a series II, being he did not really know the year.

Series II came out in 95 actually.

Heres the block part numbers:

Series I s/c: 24502134 or a 24502441

Series II early (95/96) (no pins for LIM end pieces): 24502287

Series II Late (97+) (pins for LIM end pieces): 24506029

I would post BillBoost, but everytime I try to upload, it looks for an url...
Just found out, it is a series II and it has, I mean .. only has 39,843 kms on it That's sweet.

Thanks for Your help Matt.

Goodluck with the swap!

BillBoost, unfortunately for me, this motor I bought did not come with a S/C on it. That plus a few other facts, for example, no exaust manifolds, is how I managed to talk him down in price

Matt included some block numbers, so I'll compare them, hoping it is a 98 or newer, will the 96 work? If for some mis-fortune that is what I have?

96 sc block is the same minus lack of lim gasket end piece locating pins.

I'm confused,, ... I just got the code off the block ... it is 24506029 ... also says 3800 II series
But ...
I took my S/C off my 98 gtp and it does not fit, :*(

Is there different types of S/C's out there?

Are you sure it's a supercharged engine? The way to tell is there injector holes in the lower intake manifold or in the cylinder heads.

Alrite, took fuel rail off to try, and it does not fit, so it is obvious an S/C motor... am I able to take the S/C and head off my blown motor and add it on this one?

Yes you are. If you do this, make sure you send your heads out to be inspected and freshened up to avoid further issues down the road.

High comp pistons. Youll need headers

What would headers accomplish?
More air flow...
So, guess I need head gasket, and as hitman says, get head re-grinded from my car before installing onto the new motor.
Is it worth the effort?
Or should I now sell this motor which I now know is a non-S/C 3800 and look for another 3800 which is an S/C 3800?
Learning experience ... that is for sure!

if the engine is a non s/c, the pistons will be setup for 9.4 static compression ratio (versus 8.5 of the s/c engine) which requires either a permanently open bypass valve (Not the best of ideas, but it can work) or some sort of exhaust flow mod to run with the supercharger with a stock pulley.

You could also install a 4.0-4.2 " pulley on the blower.

It can add up real quick but supercharged engines are pricey in Ontario.

Hey Matt, any suggestions of where to get the proper headers? Anything else needed to purchase?
