You may want to go to the fridge for a beer before you read any further.
Alright guys, here's the next installment.
I have the new cam in the block and I start checking the lobe position relative to the lifter bore. #5 intake(the one that went bad) is still way off. I mean the lifter never sees the full width of the cam lobe until max lift. Even then, it barely, I mean barely, catches the back of the cam lobe. Barely like by .001" type barely!!!!!!!!!!!!!!!!
This is with the retaining plate in position and the cam turning in the same position it will with the cam gear on and torqued down.
Now here's the fun part, with the cam approximately .1" forward all of the cam lobes line up great with the lifter bores. Hell, even the bearing journals line up in the bearings better. At that .1" forward position all of the bearing journals are flush with the front of the bearing surface. I made a couple of washers to go between the retaining plate and the block and gave the bolts a little torque to get an idea of what it looked like. It looks good like that. The washers won't affect the cam/plate mating surface. With the cam gear on and torqued it will keep the cam tight to the plate. Here's the kicker.
Can those massive 1/4" couse thread by 3/4" long retaining plate bolts take it? Am I way out in left field here by wanting to move the crank forward? Comp Cams tech department is of course closed today and tomorrow. I've resigned myself to doing nothing until I get with them. I just wanted to post my continuing saga here for your amusement and to get some advice. Get Some!
Here's another point of interest, the cam journals on the Comp Cam are actually wider than the journals on my old Lunati. Me thinks this is why the Comp is farther back in the block. This Lunati cam had 30K on it and never gave me a bit of trouble, other than it being the wrong type of grind for my car that is. I'll check back tomorrow. Fords are fun!
