Hello all,
It's been eons since I posted. So many ups and downs prevented me from making any meaningful progress the last 5 years but that is changing.
to recap:
250 CID 6 cyl build
Classic Inlines Aluminum head w/ street / strip porting
4 V intake with QFT 580CFM carb
Cunningham Rods bronze bushed for Chevy .927" pins
CompCams dual wound springs
CompCams Oil Through Lifters
Yella Terra Roller Rockers************
Clay Smith Pushrods
Ross Racing pistons with TBC and Molly coating
I built this thing like an anvil in the hopes of going fuel injected and Turbo Charged in the future
The issue currently preventing me from completeing break in:
Engine starts up fine and runs like a champ until operating temps are reached at which point it begins to run very very badly and I shut it off.
I took it to the shop that built my short block and they removed the valve cover to discover that the pushrods have popped out from under the adjusters of the rocker arms!
So they put the pushrods back, readjust, and I take the car home and proceed to try and break in the engine again and about 5 min into the Cam break in I hear the same noise! so I tow it back and they call me and tell me the same thing happened this time except on another cylinder. They noted to me that they had stopped using Yella Terra Producs because their rocker arms were problematic on some of their other engine builds so they are advising me to find another alternative. (if only they knew what they were asking lol!)
I know that there aren't many options for our engines and I'm wiling to bet that I merely botched the install on account of Yella Terra didn't provide Manufacturer installation instrucitons with the kit. Yella Terra has been nonresponsive to my requests for printed instructions.
Has anyone had simillar issues? does any one have the original instructions for the Yella Terra Roller Rocker kit? Is any one on here runing the kit on the Aluminum head and can advise me about the installation?
Sorry for not posting in so long Thanks for any help.
Keep Sixin
