I wouldn't do either. Go to a different yard. Hell, go to www.car-part.com and look up 2000 Pontiac grand prix and search for engine. You can filter for distance/mileage/price to find the right one.

I just picked up my 99 L67 for $300 from a yard an hour from me that I had no idea existed. Food for thought.

craigslist part outs too, i see used engines running in the car still for sale a lot. best way to buy one is to see and hear it running.

theres a few cars to search for, like regal, gp's, bonnie, park ave 's, and then theres newer 3800 like the buick luceren, you would have to swap the upper intake cause its a l26 engine but thats no big deal really.

**buck531** · 07-12-2016

if you use car-part.com and put in 2000 Regal or GTP will pull every engine that's compatible with that year.

I was looking at Cl but for a running L36 with 150k miles was going for $500 I said nope nope nope.

There's also bigger places like lkq they document the hell out of the car the parts are coming from. I was able to get a 15k L26 shipped to me.. Well work for $600. Some elbow grease, some paint and gaskets and I once I opening it up it was definitely a 15k mile motor.

This... Exactly why I bought the l26 just couldn't find any L67/32 that didn't have 100k+ on them plus the prices are outrageous. Hell couldn't find any decent price l36 either.

I wouldn't buy a reman 3800 unless it was a jasper....and even then, i wouldn't spend that kind've money, lol (hindsight you know)

**Scottydoggs** · 07-12-2016

wheres bob. hell we need our own thread for this part of the community.

did you say porting?

**jasonbernard** · 07-13-2016

Ok, I think you guys have convinced me, once I gave it more thought, it is starting to make sense.

This goes against what I thought was conventional wisdom that a engine reworked properly from a machine shop = 0 mileage engine.

I have a couple of guys in the neighborhood who race on dirt tracks (mostly old corvette engines) who suggested the machine shop route.
My daughter won't be racing this thing (at least she better not LOL).

I knew about car-part.com, but I didn't know about LKQ.

It's hard for me to find the deals you guys got, but I will keep looking.

Thanks for the wealth of knowledge that only this forum can provide.

**buck531** · 07-13-2016

I looked for a solid month. CL, Ebay, Car-part before I got the one that I got.

Stick around more. Just about everything you can think of about 3800's has been thought of before and posted in some way or another.

**jasonbernard** · 07-13-2016

Found an 18,000 mile L26 on ebay for $750.

This will be way cheaper than the rebuild route, and now I have enough extra to buy a cherry picker, which I needed anyway.

Should I post pictures of the swap progression, or has this been beaten to death already?

Many thanks!

**Scottydoggs** · 07-13-2016

start a ride thread, update it as your work progress's.

i only took a few pics along the way, dirty hands stop the camera from coming out, and i work solo a lot. no spare hands.

and its a good to have your thread to ask for any help you might need.

nice find, good luck with the swap.

**REDCRAPGP** · 07-13-2016

And check craigslist for a picker many times guys will go buy one from HF for whatever they need to swap use it once then post it for sale

One suggestion that I will make, is that you keep the L26 parts. They are a small upgrade, but an upgrade nonetheless.

And there are adapter plates available for the throttle body, to allow it to bolt to the later design intake manifold.

Just a thought

**jasonbernard** · 07-14-2016

Cool - didn't know that adapter plate existed. I was wondering if I could keep it.

The L26 TB is aluminum, right? Does it have better flow also or is the benefit just metal vs. plastic?
