Ok, In need of a pushrod length checker.

I am installing a solid tappet cam with adjustable rockers in a 440 so I need a checker with a cupped end.

The range I need I am sure is the 8.800- 9.800"

Problem I run into is I notice on Mancini's site they have it listed as part # 7703-1 which comes up as an inch shorther according to Comp Cams site. Mancini's says it comes with both type ends (cup and ball). Comp's site doesn't say specifically but offers the same part number. Comp also has a pn# 7719-1 whcih says 5/16" cup.

Anyone ever purchase one and know which one to get?

Thanks
