I've run into a problem with my engine build.
This is a '73 TR6 with:
head milled .140;
the GP3 camshaft:
valve springs per Goodparts recommendation for that camshaft;
pushrods .140 shorter than the originals;
new lifters;
block bored for cam bearings, which are installed;
new standard ratio rocker arms;
new rocker arm shaft;
Payen head gasket;
head and rocker pedestals torqued per spec.
I am trying to rotate the camshaft so that I can do an initial valve adjustment. Without the rocker arm assembly, I can screw a couple bolts into the end of the cam and use a screwdriver to rotate it. Once the rocker assembly is bolted down, I need an 18 inch lever to rotate the cam, and even then it's darn near impossible. In fact, I bent the bolts screwed into the front of the camshaft when I applied leverage to rotate it.
What the heck is going on? Have I forgotten something? Arrgh.
I did send an email to Goodparts and left a voice message, but maybe someone here can help me out.
