This is on what is sposed to be a 5.7 tpi motor in my Trini Chicks trans am V0724ANA I tried two code sites and cant find it . Does anyone have a good code site ? to check that out ? or is it even a real number ? Having trouble making out the small serial numbers 

OOOPPs that was SNA that makes it an 87 350 

 And sadly I never looked up the codes on the block in the 50 , cause I didnt really care . I know the truck originally had a 68 or 69 350 in it , and I was pretty sure the previous owner blew that up plus he eff,d up the muncie in it . Sadly it now has a ZDD  81 350 in it , but he used the pistons heads cam etc from original motor . It sounds great and pulls strong but falls on its face 54-5600 rpm
