If you read the internet and listen to guys at the track...........there is a swinging dick on EVERY street corner with an inline valve, wedge smallblock, that makes over 900HP. I have been doing this stuff for a LONG time and have NEVER seen one, be it a Ford, Mopar or Chevy. As I said, you can do it with some canted valve stuff, but it's still not REAL easy and will be at a min of 40K if you do it with all new stuff.

I have done several 434ish Chevys and Fords, with the BEST 15-18* heads you can buy. A good one will make between 840 and 880, depending on cam, compression, rotating weight, etc. I have yet to see a Mopar head that was BETTER than the best off brand, so I am going to say it can't even realistically be done with an inline head........regardless to what some dyno sheets may say to the contrary
