3/8 or 5/16 adj. pushrods

i have a 77 350 i was wondering which type of adjustable pushrods would i use?

 

i believe all 350's used 5/16 stock. the extra thickness is meant for wilder engines.

 

i thought so, but wanted to be sure. I ordered some more adjustable from ta. They didn't look like the last ones on the bottom end, but i called and talked to dave he helped me out, everything was cool they just came from a different manufacture.



I WILL ALWAYS SHOP WITH TA GOOD PEOPLE

 

I read in the T/A Performance catalog that 69 buick 350's use 5/16 diameter pushrods with 3/8 balls .
