In the spare time I don't have, I spent a couple hours in the last week hunting info on the Quad 4 motor... OK it's only reading, but anecdotes from rebuilders, hot rodders, etc...people in a position to actually know, not blind fans nor haters... It's a mess of a motor. It sure is pretty though! And makes a lot of power, and ... but there's like 6 blocks, 4 cranks, 3 rods, not just because of the two or three different displacements, but because of design flaws, head cranks, weird gasket problems, ... Originally, GM didn't "believe it needed a balance shaft" -- ignoring 20 years of successful industry knowledge -- then added one years later. No way I'd touch that thing! I'm sure you can make them work, but its' way too fussy for me. I know highly efficient alloy motors with 1 hp/cuin up and much hairier than our cast iron clunkies, but man, I have to appreciate the advantages of over designed, over built, under rated old motors. I wouldn't mind the complexity, or the rapid changes and one-year parts, but the fussyness of gaskets and assembly and cracking and all that crap, forget it! Too bad, it could have been such a nice thing. I guess we can say... "typical GM". Oh well. -------------- next part -------------- An HTML attachment was scrubbed...
