i went to go look at a 350 engine to pick up cheap and it looks to be out of some type of dump truck that he had parted out. it has a 1 barrel carb and mostly looks like a work motor so im guessing its 4 bolt. what does it mean on the valve cover it says

GM goodwrench MD 350

does this mean anything?? i

 

md = medium duty most likely

get the casting numbers off the block and post them or go to www.mortec.com and check them out there..

 

my guess is that it is an internal comustion 350. Just kidding. Actually, the carb thing is just like another thread on here. You cant tell anything by what is on the engine then. The one barrel carb could have been on any engine. With the valve covers, assuming they are original to the engine (which is a huge IF), it is probably a repalcement engine. Probably a smogged out low compression dog of an engine making 260hp with a four barrel, headers, and a lot of prayers, The one barrel carb is probably a carry over from the engine that was replaced.

 

ok. im only paying 50$ so im probraly gonna get it anyway. it looks like its a pre emission era engine. but it might be caried over stuff. anyway im just hoping its a 4 bolt

 

#1, get the casting number. #2, pull the pan and check. However, the 4 bolt thing doesnt really matter that much for a street car. And if you are truly going all out, use a 2 bolt and go splayed, its stronger anyway.
