I have a 1985 K5 blazer with a 350 and was wondering is it a 2 bolt main or 4 bolt main engine?
Hard to tell.
Get the block ID then reference on mortec.com
Even then you probably wont know for sure unless you pull the pan to look. 2-Bolt mains are perfectly good blocks, even in high-performance applications
Separate names with a comma.
