This may help or not but here goes. I was running a Mopar solid lifter cam in my 440 block engine. I switched to the Racer Brown hydraulic cam and tried using the same pushrods that was in the motor. They were too long and the valve hit the piston. I had to buy a set of stock length pushrods and everything worked fine after that. It seems the lifter is a different height than a hydraulic lifter so the solid lifter pushrods wouldn't work. And you also have to have the proper valve springs designed for the cam you are using.
