Thanks,John

 

They make an adjustable push rod, not for use in the engine, for measuring the length of the ones required after doing something like you did. I think Summit, or Jegs, or Speedway all three sell them.

 

Actually, being a cheap b@$t@rd, I would just take an old pushrod, cut a section out, weld a piece of threaded rod to one end of the cut tube and weld a nut to the other. Instant, free pushrod checker. Run an extra nut onto the threaded rod before putting it together and now you can lock the adjustment before taking it out.

 

Excellent idea Joe!

 

Hey I like this site already...Very useable info. And I am glad to see there are more cheap B@5T@RD5 like meBut I prefer THRIFTY.
Thanks JOE .
