Pushrod Length 347 with #317 uncut (lightly surface) heads and an MTI Stealth II cam... Would 7.4" pushrods work? What REALLY affects the length, I have heard of different base circle cams, I do know the stealth II is on an XE profile, but not sure how that would affect pushrod length. Maybe someone could chime in and clear this up for me. I have a set of hardened 7.4" pushrods, need to know if I need something else. Oh btw - I have Harland Sharp 1.7 non adjustable rockers.
The correct way would be to measure it up and buy the exact length. I am guessing with heads that just have a cleanup though that the 7.4's will be darn close. The base circle is slightly smaller, but your heads are shaved(how much??). Interested in seeing your dyno with the 918's, boost, and harland sharps. I would like to see if you get valve float....post up when you get it going.

Stealth II base circle is XE-R and .04x smaller than stock.
I used to run that cam BTW.
