BT, how do you know this? lol!

20 years ago, 427 bbc alcohol drag motor, Cloyes trueroller, multipe keyway crank gear, takes the time to CAREFULLY degree in solid lifter Ultradyne cam, uses offset bushing in cam gear to get it just right, disassembles engine for final cleaning, you know the rest... Yes, it's easy to do, ONCE!

ok here is what i found.... the intake rocker arm of cylinder 5 was chattered off of its mount and the pushrod was destroyed at the rocker arm. it sent the end ball about half way down the pushrod causing it to split. the exhaust side pushrod was bent into an s shape. the lifter looks fine and both pushrod ends at the lifters looked good. i used a borascope and found no signs of contact between the piston and valves. this may have been my noise. i prob. should have adjusted the valves again. i dont know what i did wrong. i have big gil anti-reversion tails and my manifolds pass at 20 psi submerged in a garbage can full of water. WHAT DID I DO?

You adjusted the valves wrong.....look up the proper sequence and procedure, put it back together and hope for the best......you may have a bent valve or two. The lifters should be fully primed.

What version of BB are you running? Do you have the Mark IV or GenV cam or the Gen VI with the stepnose? I just learned today how to adjust the cam endplay. If it is not set correctly you can have big problems.

take a look...... i am going to go back through the entire valvetrain. i set them up empty lifters (brand new) adjusted to zero lash and then 1/2 turn after.

gen v block and gen 6 cam no button... using the gm performance bracket and single roller chain. the cam cannot walk due to the bracket between the sprocket and block.

I pray the wiggling pin hasn't fallen out the wobbling hole.

were the valve springs matched to the cam for pressure and lift? possible coil binde as stated before.

145 lbs installed.... i think this lifter set might have bottomed before i hit zero lash and i didnt feel it due to them being new. and they pumped up and screwed up the whole mess. i suck! this is my first BBC ever!

It is easiest to adjust the valves with the intake off. Then you can actually see when you are at zero lash.
