Title: block casting and suffix code don't match
Post by: dab67 on February 09, 2006, 11:57:46 PM

 ???CRG!!!!!!!!!!!!!!!!

I was looking at a block on E-bay. The casting number is 3970010 (302,327 or 350) but the engine assembly plant stamp and suffix code  (V0105TDB) if I am interpreting this correctly states it is a 307?? Or am I missing something?????

Thanks

TDB can also be a 1980 350-165 hp fLS9 rom a truck.  Need the casting date to confirm.

Has to be the 1980 350 as the 3970010 was cast as a 350 block.   Millions of them and very few were 302.

It's a 1979 truck 4-barrel 350/165hp, cast on December 22, 1978 and assembled on January 5th, 1979.

I agree, where I got the 1980 from must have been another code nect to it.
