I just installed a 429 ford in my bronco. It runs ok but the lifters are very loud. The motor was rebuilt 2 years ago and sat ever since. I so far have put some sea foam in, but its not helping so far. the rockers are the non adj type, and when off the high side of the lobe there is a good deal of play in the pushrods. I am thinking some or all of the lifters are sticking, Im thinking i should replace them, i picked up the lifters( 44 bucks for the set, gotta love discounts) just in case so all i need is the manifold gasket. but before i go thru the work is there any other tips? It doesn't seem to rev out well but I cant really tell yet as the power steering pump is out of alignment and i don't want to risk throwing the belt. When i fix the alignment i will rev her a bit. I know the cam lobes are good i just put on a weiand intake and looked at the cam while i was in there. thanks for the help.
