Bob can you elaborate on the timing???

But you also made the statement that 2 x 1050's is too much carb.

So....what makes you say that ?

29 total will put the egt,s sky high,even inconal exhaust valves don,t like that very long,not to mention the heat the seats are seeing.

8psi, stage 4 BDS 10-71, 651 cam, head work by the best (hi-flow heads) and 2 Nickerson 850`s (soon to be 1050`s) 32* timming = 893hp @ 6500.
So that`s a sweet correction factor on your dyno

Edit:

540ci. 8 to 1

Mike, I run 30* & 91 octane. I would be afraid to run 32 or higher on 91 octane. Do you have egt numbers on you motor...like say at 28* 30* 32* etc... Just curious how much it differs... Also, Im sure you realize, that cyl pressure & afr, change where the best timing lies from motor to motor. I think thats why some guys that run more timing in boosted motors claim they run better when way fat, like 10 to 1. Merc ran 32* w/ 8to 1 900sc & 28* in a 7.5 to 1 800sc. I dont think the 800 had inconel vales?
