So i have kinda had a semi secret sortof ambition to have the fastest L27. I kinda felt like I was givin' an N/A and i'd stick N/A loyal. So i threw the L67 swap phrase a few times but mroe jokingly i think. Now I am really considering this one, from Mr. Morad: Series II L67 /w 4T65-HD

Its another option there. Its cheaper even with shipping than both rebuilding what I got and buying a reman L27, since the trans rebuild wasn't included with the $1600...

Umm, so if I was to go about exploring more of this option is there anything else I'd need or have to modify?

The following accessories are included in that auction:
-Power steering pump
-Engine wiring harnesses and fuse box (no cut wires)
-PCM
-Alternator
-A/C Compressor
-Coil packs
-Starter

Are the mounts the same throughout the '92-'99 body?
IIRC the axles are differnt too...
anything else?

I just want to fully explore each of my options...

I like the SII L67 route...though I may be a bit biased. That'* a pretty good deal for the engine, trans and accessories.

Yeah the axles I believe will need to be swapped out. And alot more.

In fact, you may want to read up on my OBD2 conversion. Some of what I had to do, you will have to do as well. The physical swap is a non-issue. The wiring will be something else entirely, and you will have to be VERY patient and methodical when doing it.

Oooo, I'm not electrically inclined...but I'll go through you OBDII conversion anyway. It'll take me frikken another two months I bet...

you said Axles and alot more...?
what else would I need?

[Edit] 2000th Post, woo hoo!

Hardparts should almost be all set in that Morad combo. I'm talking about getting all of that to play nice with your '93 wiring.

I doubt the fusebox will come with that combo...maybe if it came from a G/W body, but not an H. You will need to go through your original '93 harness, and chop out everything except oil pressure, ECT gage feed, and low oil level feed. You will lose T2V unless you want to put in a sine-to-square wave converter to feed a 2k speed signal to the chime module. You will also need to splice in all the power conduits from the old harness to the new one so you can retain the original fuses and locations for the new computer.

On the computer side, you will need to program out the VATS, the oil life and oil level, generator charge, and anything else that your '93 does not posess. You will also need to wire in a new OBD2 harness head into the cabin. Given your schedule, it will take you several months just to complete the wiring.

Like I said, the mechanical issues are nearly non-existant in your case. It'* the electrical aspects that will kill you timewise. The electrical layouts between the pre-96 and the 96-99 are substantially different, and is NOT plug-and-play.

EDIT - I'm changing the headline for you

Thanks, but yeah...so much for the 'cheaper' option. hmm
If I had another car I wouldn't mind so much. Its been almost 6 months already.

If I could find a Series 1 though, that wouldn't be (as much) of an electrical nightmare would it. Buying a reman L67 would be about $200 more i think, I'd lose the core charge since I dont have an L67 to give them. Plus I'd still be out on the HD Trans, Axles, PCM and Harness.

Well back to the L27:
Front main bearing:


And check out the cam bearing :


#3 Spun a rod bearing. The crank looks pretty good except for that #3 lobe it thrashed, I'm not sure its usable due to that one. You can kinda see it:


You can definitely tell in this pic of the bearing:




And the rest of the stuff, Dad made the comment everything on my motor is smaller than his and I laughed, and he'* like "What, what are you gonna say?" And i said I'm fairly sure my rods are bigger than my dad'* but he doesn't want to believe me :

A core is a core. There is no difference externally between the two. Nobody would be able to tell your motor from a supercharged one. And if it is a really good rebuilder, they would put in all new pistons and rods anyways (if they bore the block, they at least HAVE to change the pistons, so giving them non-*/c spec is a non-issue). All they really care about is if the block is in good shape (no cracks), the heads are serviceable (which they would be), and if the crank can be turned (which it should be).

And a L67 reman long block (or short) will be the least future headache. A little beefier, and all your L27 specifics will bolt right up.

Interesting idea. Advance apparently doesn't have short blocks, at least not for the 3800. I'm sure they'd have an L67 Long block though. I like that idea.

So the heads are the same?
