Been going thru my NOS 235 hot rod engine parts and found a camshaft kit springs lifters push rods. the cam paper had faded out and is unreadable. It is a Sig Erson 110515 290F. If i my memory is correct it is 515 lift 290 duration ??. I also have a new set of jahns 60 over dome pistons and a harper 3x2 manifold. Might build another 235 as i have a good block and a few 848 heads left.
