Guys, been trying to find a flex plate and starter for this thing for a few months. So casting numbers as follows,

GM 5.0 LG SGI, 14093627, Heads 14102187, And finally V0616SDA. Some of the info I looked up was a little contradictory to each other. The casting code shows 87-91, the heads 88-93, but the suffix code brings up 84.

The flex plate will be a weighted one for 305, the small block chev became partially externally balanced when GM went to the 1 pc rear main seal design. the 305 and 350 after 1986 use the same weighted external balance flexplate. you can choose whether to run 153 or 168 tooth plate depending on what torque convertor you are fitting.
Your motor being a TBI engine was probably pulled from a 88-91 Chev 1500 1/2 ton
