My mechanic just called me, and we are having an issue with the the intake pushing rods bending when installing the cam sensor and priming the motor. The roller rockers are T&D 1.65 rockers that I bought from a board member. However they are older style rockers, but are suppose to be 1.65 ratio. We were using the same length pushrods I was using with stock 1.55 ratio rockers, but it appears the pushrods had 20-30 thousands taken off since the motor had been decked in a previous rebuild. So the pushrods were not exactly stock length. My question is, is there any explination for only the intake pushrods bending, and not the exhaust? My mechanic has suggest that possibly the exhaust rockers were 1.55 and the intake rockers were changed to 1.65 to get more lift. He told me this was an old practice, but since the rockers are older style, we are not sure.
I know that I will need a good set of adjustable pushrods, however I am try to determine, if the rockers are true 1.65 ratio all the way accross, or if they have 1.55 on the exhaust rockers, or there is another reason that only the intake pushrods bent?
Thanks for your advice in advance...
