Just studying some cylinder head potential, and got to dreaming. I was wondering what is the highest horsepower anyone has gotten out of a 10.3" deck motor?

What about the highest horsepower with a Hemi layout?

Details please, if you are willing to share.

I'd think in a max effort hemi 1600ish wouldn't be out of line n/a. Of course that involves alot of rpm and $$$$. Something in the 690" range.

4.7" bore and 5" arm will get you there, and it can be fit into a 10.3 Eliminator block I believe. Cool

I know the Thor's will go over 1300 hp properly set up, and that is the top of the line in wedge heads for the BBF. Cool

What about the A460's for a slightly more conventional head? What is the highest horsepower anyone has seen out of these heads, especially with their cast tunnel rams?

I think the king of the hill on the A's goes to Phillip Oakley's 604 @ 1100+hp, unless you get ole Hemi's buddy to build you one that did 1300.

Our A head 557" dyno'd 1110hp. So, obviously 1100 is doable...

I had the same combo, c-heads 13:5 compression, sheetmetal and 2 BRE 1200 cfm carbs and made an honest 1200. Are you using a N20 cam with your injection ?

I had a horsepower cam in mine. Never had N20 on the motor.That will be a new addition this year along with the N20 cam. I,m going to try 350hp in a single stage.

1152hp with a N/A 548 with C-heads and 2 1150s. Probably makes more now with a plenum spacer since it went the same ET and .7 mph more in 2000 ft worse of air so maybe 1180 ish???

MAX for it to live in a 10.300 is about 4.635 or so arm, a 4.750 will fit but the piston will come out of the bottom of the bore way to far,and you will be changin them often,rod lenght,and pin hight,and the oil ring is another problem
