I have swapped a ly5 into my 84 c30. I did the rebuild. All new bearings, rings, lifters, holly carburated intake. Edelbrock 1406 carb, msd 6014. Ok it starts and runs but... problem 1 lots of lifter noise.. sounds like a diesel kinda in the valve train. Not all the time but most. Has kinda loose clearances but not outa spec. ohh has a elgin sloppy stage 2 cam with springs. problem 2 I cant get this thing to take wot without it Fallin on its face 1/4 throttle it's fine ibcan rev it all the way out but anything pas t that it spits and sputters. Any help would be appreciated 🙏
