years ago, at one of the cobra builders/ engine shops, I had some work done on my FE 427 (429 displacement), and got 455 rwhp. That same cobra/engine builder had installed numerous roush 427r's, and I think the best rwhp he ever got from any of the crate roush 427r's, was around 420, even after dyno tuning with the best side pipes. So, it depends a lot upon the dyno.

I called Keith's shop and spend about 15 minutes on the phone with them. they said 175-180 per cylinder.

As far as the 10 quarts go,that seems like a lot,but you can easily find out,most A/M oil pans (canton for sure) have the parts number on them, easy to see if the car is on a lift, check what type pan it is,take a few measurements if you can't find the part number and look up on their site and you should be able to get the capacity........

I've never seen a Canton SBF pan that held more than 8 quarts,too much oil can be as bad as too little oil......
I have a Canton 8 quart road race pan on my race car and a remote larger than normal filter with 12AN lines,probably a total 8 or more feet of lines and it only holds 10.5 quarts and that's including the oil cooler......my filter alone holds 1.5 quarts........

It is a Keith Craft. Didn't look on the pan when I was under it but the original build info from 2004 has a Canton 15660C listed....I looked it up and I've found the 15660C to have a 7 quart capacity. I've got an oil cooler on the car. That damn dip stick was dead at the bottom of the add line at 9 quarts. Will check it tomorrow to see where the oil level with the 10 quarts in it.
