Reply With QuoteCan't answer your question directly as I have a different engine but to ask the obvious - Summit have a good reputation in the US, have you called them?

new push rods help required
Hi all, I have bought a new set of push rods for my Ford 429 engine from Sumit racing in the USA which a friend kindly carried back for me.
When I unpacked them it is clear they are physically different so I thought I would check with the forum for peoples thoughts.
The old rods have a ball which looks like it is welded to the end of the rod, the new rods just have a domed end. They both look like the same resulting diameter but would like some reassurance before fitting them !

I have emailed them but been searching internet this evening and have found several sites offering 'formed end' rods which are this shape so I am pretty sure they are ok to use.

Fitted the new push rods over the weekend and managed a quick test drive today. Engine seems to be running just fine and my ticking has gone which is great news.
going to change the oil and filter this week to make sure I get rid of any debris from the old rods wearing.Paul
