273 Pushrod length

ok, did some measuring. for hyd cam and adjustable rocker, they list 7.234. solid cam lists 7.342. on page 307 in older book, tells how to measure pushrods correctly. they use a .3125 ball in cups, this is how pushrods are measured correctly. you subtract .3125 from measurement, this gives you their measurements listed. so, 7. 234+ .3125 = 7.5465. solid cam pushrod is 7.655- .3125 =7.342 the 7821 rod will fit with hyd cam and adjustable rockers. also, mopar hyd lifter cups sit way up in lifter. the comp hyd cup sits lot farther down. closer to solid cup height. so the pushrod they list is correct length. BTW, smith bros measure all their cup pushrods this way. I use their calipers to measure with.
just food for thought
