1970 Blazer correct 350 suffix code
I need to know what the correct suffix code is for my early build 1970 4x4 Blazer, 350 w/auto trans, St. Louis plant. I was told it could have been a TAX, TAY, TBC or TMJ. Hope to narrow it down. Thanks

Re: 1970 Blazer correct 350 suffix code
I think this best matches TAY 1970 350 convcab, t350 - 255 4 K-10 to 2500 Here is a good web site http://www.nastyz28.com/chevy-engine...ngs.php#suffix

Re: 1970 Blazer correct 350 suffix code
Sounds like you might have it. My 71 Blazer was TBG.

Re: 1970 Blazer correct 350 suffix code
You guys may know this but decking the block in a rebuild can/will remove the stamped code so may want to skip that.
