TTI Headers 2.125 x 3.5
I know it wasn't tested here, but you have had previous experience with the Indy cross ram. Whats your guess if this motor were equipped with the Indy cross ram as far as peak torque and overall power numbers?
The last engine I dyno tested with the Indy X ram was my 512 with Brodix B1BS heads that I had in my Coronet it made 880hp and ran 9.0s at 3400 lbs

BMBBR5 Roller Cam 283 on a 115
Can you give us a little more info on that cam?
LSA 115 (wider than I expected)
Intake/Exhaust at 0.050" 283?
Lift with the 1.6 ratio?
I bought your BMBB 3R from another racer for my 540 CID, 345CNC.

The big tubes lost quite a bit of torque for a few horsepower gain. I would say the smaller tubes are a better choice

I liked the straight 2.125" headers. They made more torque and the horsepower pulled to the top of the pull (7400rpm). That surprised me with 572 CID. Perhaps the cam and 3X intake?
I am willing to bet the exhaust duration at .050 is over 300 degrees with that wide of a lsa. That would provide enough overlap in the "fifth cycle". It would also keep the other three opening and closing points close to what other cams have with less exhaust duration and narrower lsa. The exhaust opening point is the one that would move around( open earlier) if I am right.

Thanks for the cam card.
Comparing it to your 3R cam I bought (used) it is 4 degrees longer duration, 3 degrees wider LSA, and the same lobe lift. That is in line with going from a 540 to 572 with your builds. And with that user's 1.6 ratio it comes out to .754/.722 valve lift.

If you don't mind me asking...
What kind of flow numbers did the heads produce?

I opted to not have them flow tested they are OOTB -1 345s (but I did have them port matched them)
