March 19, 200421 yr comment_73353 Originally posted by Mr Camouflage The L28 on a 280c has 135HP with a down draft carbie and manifold. Take that off and put on twin SU's and manifold from a Z and it will rise to at least 170HP. Keep in mind a 280c L28 has a less aggressive camshaft profile. But all in all your point is quite valid .
