As my title suggests, my 392 with a cam swap has a rocker arm clearance problem. When the valve is all the way closed, the rocker arm body is hitting the spring retainer instead of the rocker tip on the stem. Its a TSP cam kit wtih 585 lift, PAC 1232x springs and the reccomended r311 retainers. Using johnson 2326 lifters and TSP supplied pushrods. How should I go about fixing this? Its a pretty servere contact issue. The damn rocker tip cant even touch the valve stem when the valve is closed. When I had the stock retainers on these springs, I didnt notice this issue. But I dont th8nk the stock retainers can survive 450 lbs.
What Bob said, and that retainer looks wrong ? My Drag Pak 392 was 0.605 Int lift and had 0.10<0.14 of clearance at the (chamfered edge) retainer! Try looking at what Comp Cams has to offer?
