Bench Racing: Highest horsepower N/A 10.3" deck engine combo's
fox331 on January 30th 2010, 8:59 am
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.

Is it possible to get 690 out of a 10.3 block?

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

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...

what about a c-460 headed motor? My c heads peaked at 515cfm and are going on a 598 a460 block about 13.5:1 comp, Nitrous deal, sheet intake and twin 2000cfm throttle bodies.

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 ?

With out a power adder ? Nevermind the details. Is he taking new customers? Please give me his name and number. My cousin has a 604 a-head collecting dust that needs to be completed.
