Very nice build . Are you using 2 gaskets to get the valve covers to clear. I would be curious what the dyno numbers would of been with the stock exhaust manifolds to keep that stock appearance

These guys are pretty good at coatings. I have used them lots. http://swaintech.com/race-coatings/

Hi Brian have you had any (powerbond)that the pulley bolt holes were off. Brent

sorry about that I thought you were talking about valve lift and duration .

The following timing is taken at .050" lifter rise and gives a more accurate determination of camshaft position.This info was is the timing chart from Isky but very close to the MP. the link is below. http://www.iskycams.com/Wcc422c9a48168.htm thanks again for everybody help

I have resolved my problems. What I did was I used a roller lifter :oops:to gain some height for the dial indicator that would explain the 11 degrees, not thinking about the surface area. rechecked with PROPER LIFTER Intake duration 255 Exhaust 254 Intake CL 108.5 Exhaust CL 113 lobe seperation...

I get the same numbers over and over so i think im good there but will check again thanks.

Going to put the isky 555 cam back in that has very similar specs and check it. This is driving me crazy, the cam must be ground wrong

Checked tdc it's perfect.

Reading it off the #1 intake lifter

Degreeing in my first camshaft not sure if the cam is ground wrong or I'm doing it wrong. Intake CL 108.25 and Exhaust CL 112 which are good , Lift 372 thats ok but when I check duration I get [email protected] Setting dial indicator to zero at base of cam rotating to .050 on the dial read...

Yes I can do that very good idea may take me a couple of days. 7200rpm

yes they are a mix

Very close to what what Crackedback said .And the pictures look the same as mine.Thanks for all the support I will try different ends .

Shafts look fine Isky Part No.390155 INT .555 .014 296° 263° 106° EX .555 .016 296° 263°

Sorry I should have mentioned this, there is 6 that are worn\damaged. The tips of the valves are fine. Yes I have checked the geometry all is good .I run close to the same setup on another motor never had any issues. poor assembly maybe or some soft lifters??

yes I believe it to be the right radius 5/16. it looks like all my other solid pushrods

it is a half ball pressed in .there is no damage to the push rod on the end or the edge of the shaft? not all the lifters are damaged?

has anyone had any problems with the lifter cup being worn away by the pushrod when using a W2 race heads.mech 557lift 5/16 smith bros pushrods DC roller rockers springs are p/n P2946353
