Re: Made in mexico engine blocks
It's been several years, but as best I can remember, GM dealerships sold replacement engines called "Targetmater" from the late 80's to early 90's. The engines were made in Mexico, and as best I can remember were new engines not remanufactured. In the early 90's GM had several service bulletins about the cast iron quality of the Made in Mexico blocks. Not long after the service bulletins about the cast in Mexico blocks, GM dealerships started offering new "Goodwrench" engines. The 462624 head casting is a very light cast head, JUNK [img]images/icons/frown.gif[/img] in my personal opinion. I still like the cast in Mexico 993 heads. I'm not 100% positive, but I seem to remember the cast in Mexico 3970010 was a four bolt main 350 engine, that allowed the oil pan dipsick to be located on either side of the block. I seem to remember the oil pan was unique to the cast in Mexico block and actually had contours for an oil dipstick on both sides of the oil pan. It's my humble opinion, the engine should be OK, but check with your local GM dealership for the history on service bulletins to see if the engine serial number you have was subject to a recall.
