Didn't figure anyone would be interested in the details since it's a blue oval product.
Got the graphs but can't scan 'em till tomorrow.

A 434 makes 604 at 7000 with a solid roller? I would hope so. That's "only" 1.4 rwhp/ci, nice, but hardly unusual for that spec. If it were my engine I'dve been pissed if it was less. The recent 504 rwhp LS1s are at 1.46 rwhp/ci, and that on hydraulic cams. Strong motor all the same, congrats.

Until you've been there and done it, don't quote rwhp/ci numbers like they mean anything. If you think it's just as easy to make 1.46 on a large ci motor as it is on a small motor with the same architecture and head design, you need to try it.
If you don't believe me, check out the numerous disappointing LS7 headed attempts on this very board.
I'm not saying this engine is anything special, but the graph it produced is definitely unusual for a 4" stroke sbf with inline heads on pump gas.
Oh, and thanks for the congrats.

Are you happy with this power level?
Couldn't remember what the TWR's made.
These are 20 degree TFS High Port heads for those who don't know.
