I know I haven't been on in awhile, been busy and all. I no longer am using my LeSabre...I just felt it wasn't reliable enough for the 700+ mile a week . I now have, please don't rip on me for this it was all I could afford and it does have potential, an '03 Grand Am SE2. Anyways onto the topic of this thread I was on one of the new sites I found because of the Grand Am and found something very awesome. As far as I know no one has really done this yet over here so I thought I'd let you guys know. Check it out!!!

DBK2 has done the Top Swap oh his GP.....i done believe that anyone has dont it on a S2 Bonneville....But there have been * few that did it on the S1....and a few more that are trying it

Well then this kit makes it a bit easier and more practical for some then, it kinda makes me wish I could keep my LeSabre. I gotta sell it though need the money for the new car unfortunately.

There are advantages and disadvantages to "top swaps". I do like how it can be easily done to any 3800 vehicle though

where in WNY are you?

I would also consider doing the top swap, but I need a S2 first...

Well on this note, I wouldnt consider this a good swap because you also need to consider the bottom end of the engine. All L67 have forged cranks and rods and heavy duty pistons along with high flow fuel injectors. The ECU would have to be recalibrated or replace for this matter. I remember back in the 1970 when putting on the B&M blowers on 350 chevys were common but the motors didnt hold up do to compression ratio'* and for not having the bottom ends built to specifications of having a blower. It will work but for how long will it last is the question. Aftermarket stuff sometimes isnt as good as what the factory installed. But see if it works for you, let us all know how long it will last or if it saves gas mileage like the true L67 does.

am i missing a step here somewhere because as far as i know, all grand ams were either 60* motors or 4cyls

FYI some of the 3800'* that are making the most HP are using L36 bottom ends....Reason is that the parts are lighter therefore reducing weight......

and the higher compression helps

What is the overall longevity of those "weaker" parts though?
