Re: pushrod question
flat tappet cam? You need flat tappet pushrods. 7.8", give or take a bit, depending on factors.
A pushrod length checker is a good idea...

Re: pushrod question
That is downright bizarre....
If it was me, i'd still buy a $14 pushrod length checker, and find out for sure.
I ended up finding that 7.875 or so was best... I found some ford cleveland pushrods that were 7.890" or so, and bought those. Heck of a lot cheaper than custom length pushrods (cheaper by $40...)
