I finally found a replacement engine for my 98 GP GT.......a supercharged 3.8 from a Buick Park Avenue. Wasn't planning to go this route, but the price for the whole car was only a whopping $300, cause the tranny is toast in the Buick. Now, I know what I need to do tranny wise to hook up to my non HD. My question is, what parts are relatively easy to replace for preventative maintenance in a L67? Thinking all gaskets, crank position sensor, larger Mallory wires around 10 mm or so, plugs, etc. I have a SD stainless steel header set that will be going on while the engine is out. Might do a the cam too. Still need to read/search further. Both cars are untouched at this point, nmd I am trying to get all of my research and parts ready.
