the later ones, like 85 on are rated at like 115 @ 4800 and like 136 @ 2800. so generally an intake and exhaust gets 10-15 at the wheels on a 4 banger, so you probably have an estimated 125-130. same combo i got. for now. hauls though.
how much would this have. i just built a 4 cylinder it has a 22re block bored .040 over crank turned .020 ported carburated head, header, dual side draft carbs, it only has a water pump and the alternator on the belt. just wondering
