I just put a 2005 Bonneville 3800 non-supercharged short block w/81k miles in my 04 GTP Comp G.
I have yet to tune it for the 'bottom swap' but it's running great (aside from the need for a tune which is preventing me from getting on the throttle more than 10%).
Once I get the tune I would fully ...

DON'T use FelPro exhaust manifold gaskets -they are paper and will blow out in a very short time.
Reuse the factory multi-layer steel exhaust manifold gaskets and you will have less problems. If you insist on getting new spend the extra $ and get new ones from GM.

Nice numbers Randy!
Torque usually doesn't jump as much as HP with a cam from what I've seen.

Best way to prevent coolant getting into the bottom of the engine when you remove the LIM is:



1. Remove the knock sensor from the front of the block (white single wire connection located between the AC compressor and the starter) -you may have to stick a screwdriver through the sludge that may ...

There are a couple reasons why the 00+ rear shocks are nice compared to the 99-older rear struts:
1. 00+ Rear shocks can be bought new online with shipping included for under $100.
2. 00+ Rear shocks are a piece of cake to change -even an amateur can change them in under an hour and no special ...

If you are referring to your 2000 SSEi -get new rear shocks.
2000+ Bonneville/Lesabre/Park Avenue's need new rear shocks every 70-80k miles, or so it seems.

I would highly recommend a universal fit Magnaflow from eBay or http://www.jmfmufflers.com/
I would recommend a 94106 universal 2.5" cat.
It's what I had in my old 98 SSE and my first 99 SSEi and did very well.

I found this site and these are the best prices I've found for some tires... even after shipping most tires I priced were cheaper after shipping was figured in than buying locally.

75mm vs 65-67mm inlet

These two differences make up a big part in the superior efficiency of the Gen V over Gen III.
Even a fully ported Gen III doesn't match the capabilities of a stock Gen V.

That's the Park/Neutral switch.

Let's go back to square one here...
You say it is surging under light-moderate load?
What are the problems that are happening with the transmission?

L67 injector o-rings should be the same size on both sides -they didn't change injectors on SII L67's at any point 1996-2005.

Also, DO NOT use FAIL-PRONE (FelPro) lower intake manifold gaskets -use GM part # 89017816 or 89017825
Coolant elbows 47065HP (Dorman Help section at most any parts stores ...

That is a sharp car -love the color and with that low of miles it really is a gem no doubt.

Just to help rule out the cause for the KR -are you running 91+ octane fuel?

Also, if they aren't shot already maybe it is time to do a coolant flush at least, or if you are willing update the Lower Intake ...

Dang!! Really digging this! In the pics those KV5's look too good for winter rims!

Drive the G8 up, stop in Sauk for a Tech II session and we can take your G8 on a test drive to Browerville.

IIRC 94/95 L67 still just had one knock sensor.

Correct -the knock sensor is in an oil passage directly above the oil filter adapter/oil pressure sending unit.
Dropped a 94 Park Ultra L67 in and just have to put the belts on, the new exhaust flange donut and should have it running within the ...

I have several L67 lower intake manifolds here in central MN along with a good machine shop that offers small town pricing (labor-wise) that would allow you to save at least $100 and not have to hassle with paying a core charge up front.

I have a customer wanting an engine for a 95 L67 car and I have a line on a couple 92/93 L67.

I know I will have to swap the supercharger/TB off the 95, but are there any other reasons I can't use the 92/93 engine?
What else would have to be swapped to work in the 95?
In my research I read ...

I will let Randy (Larz01), as well as Lamp (GSX clone) and my buddy Jeff (02 GP GT topswap) know as well.
