What are you looking for? Are you talking HP? 280 is the full bore Aluminum head pro 4 motor........... 210 is a realistic # for a good steel head motor with extensive port work.
I tend to agree with HeadHunter, regarding the HP out of a well-worked 2.5L iron head & a flat-follower cam. With an Esslinger ARCA aluminum head & a .600"+ lift roller cam with a couple of 50DCO side-draft Webers....... now you're looking at some serious HP ! I've seen 317 on an engine dyno. -Dave-
I agree with Headhunter on this one. Call Tim Yates @ Johnson Machine 864-697-6067
he has dynod motors like you are asking about & will have a good idea what HP #'s the motors they are building make. Also keep in mind that the same motor will have different HP #'s on different dynos.

dead on ferrell u nailed it !every dyno is different but 280 is way out there!! it would take a really really good combo to get that with a iron head!!
262 with the aftermarket iron head from Performance. That's a reasonable build...nothing over the top. I'd say 280+ is doable with the aftermarket iron head.
