Are the pushrods to short???

306deranged · 10-20-2010, 03:47 PM

Alright guys, some of you know i had some problems with my main bearings and ended up having to get the bottom end rebuilt by my machine shop to fix everything. It spins over perfectly now. Now I have a new question for you lol. Look at the pictures and see if you think the pushrods are to short. I have stock e7 heads, OEM length 6.250 pushrods, 1.6 rr's stud mounted, Comp 986 springs. When the valves are closed and the piston is at TDC the roller seems to be high a litle bit as youll see in the pics. But when the valves are opening the roller slides right into the middle of the valve stem. My question is Is it supposed to alwaays be in the center or only when the valves are opening? Once again thanks to everybody on this forum for your answers and help throughout this project.

Vaves closed

Valves opening
