Wasn't able to find what I'm looking for through the search function, so this seems like the best place to ask.
I am looking into any difference from years to models that the 3800 S2 came in. Long story short, I am looking to replace the motor in my 99 Regal LS. I replaced the intake gaskets earlier in the year, and a couple months ago it decided to start making some unpleasant bottom end under load only noises which I am assuming is a spun bearing. After looking into machining and rebuild kit prices, the most cost effective fix is to simply buy a total loss vehicle with a good running drivetrain for < $500 and swap the whole thing.
Since the L36 came in many different Chev, Pontiac, Buick and Olds vehicles, are there any material differences in the long blocks, sensors, or wiring that anyone knows about? I’ve also thrown in a couple lowball bids on some L67 cars (two Park Aves and one GTP), and assume that it would be as simple as swapping the engine/trans assy, wiring & computers.
Everything that I’m reading says that a L36 is an L36 is an L36, be it from an older gen 96 Regal to a 00 Intrigue to a 03 Grand Prix to a 98 Impala, but if anyone is going to warn me about other things to look out for, this would be the place.
And just to clarify, I am looking for engine, wiring and sensor differences, as I am aware of the TQ converter, Final drive and transmissions line differences if I decide to swap the engine and transmission together.
I appreciate any suggestions or concerns that may be offered.
