Need help identifying motor!!
Sold my old truck and just got me a 84 swb that's really straight and is lowered with I guess a 350 motor? Has center bolt valve covers and converted to carb with weiand stealth intake and edelbrock 1406 carb. I looked behind drivers head for casting number and all I could see was a gm stamp and it said 5.7 LG and then right under that SGI no other numbers?? I felt around and looked with flash light and saw nothing. Can anyone help me figure this out???

Get the numbers off the pad at the front behind the alternator. The pads part of the block deck the heads sit on.

Re: Need help identifying motor!!

Re: Need help identifying motor!!
If the center bolt valve covers are original, it should be '87 or newer, they came out with the 1-piece rear main seal and TBI.
