thats some IMPRESSIVELY HUGE #'S for a 522ci and this is considered a small engine this day and time. :shock:

I hope the Guy is reading this that told me 1150 hp for a 18 degree Big chief 565ci is a little agreesive.....i will let your post and 522ci #'s speak for this issue.
Congrats i am Very impressed. :D

Bjuice whoever told ya that is wrong for sure I know of a few 565 Big Duke motors without a ton of effort making 1150.

yeah i know Hammer Thats what i tried to get across to just to be told it was far fetched.. :roll:

ah guess I didnt see the wise "par" crack there. One thing to remember them dukes IMO are a lot better setup then the old big chief stuff. One of the 565 I spoke up is a buddy of mine he also has a 584ci big chief motor that is .25 slower then the 565 big duke and made 115hp less on the dyno. They were less then impressed with the 584 compared to the 565 with duke heads. No doubt 1120-1130 could be had with the proper builder with the right 18 degree setup. Anymore 18 degree is old school 18 degree guys are going either to 11/12/14 degree and the 16 degree has really came into the picture. A lot have switched back to the conv heads because todays heads bb3x's can keep up with a lot of the 18 degree setups without the issues the 18 degree stuff is known for (lifters). :D

These # are from a dyno-jet chassis dyno @ the shop where i work.I know my exact driveline loss. I engine dynoed then stuck in the truck w/o changeing notning. 31%. This is with 3 1/2"s of carb spacer using the new Brodix 1913 intake design. Needless to say to say the intake is going to have alot more work done on it in the next few weeks. Stronger #s (maybe).

Those 565's @ 1150hp is 2.03 hp per cube

my 522 is 2.049 hp per cube with RFDs, port work :shock:

:lol: :lol: .....8000-8800 on a BBC you better have a good foundation like dart/merlin block.....Why are you thinking about buzzing a BBC that high for? Just a question? most BBC create their HP between 5500-7000rpm....or are stump pulling low end engines.....hmmmmm just thinking if you add a 200 shot to that 540 1000 ponies.....just a thought
:wink: :wink:

HIGH RPM 540
 

BECAUSE I WOULD HAVE TO RUN OPEN CLASS AND THERE IS NO OPEN CLASS IN THIS AREA. IWANT TO RUN ALL MOTOR SO I MAY HAVE SUCK IT UP AND BUY A DART BLOCK AND BUILD A 572 OR 598 THIS MOTOR WILL BE PUT IN A S-10 4X4 FOR DIRTDRAGS/MUDBOGS . MY 468 WAS BUILT WITH A LITE WEIGHT ASSEMBLY IT WOULD ZING . IT DON'T HAVE ENOUGH POWER TO COMPETE AGAINST SOME OF THE BIGGER MOTORS I WOULD GO AGAINST.[/img][/url]

Re: HIGH RPM 540
 

Yes sir all motor classes flat out get it anymore

low deck combo 582 and be done :)

Re: HIGH RPM 540
 

....yeah but may be down on hp but the right shot ot NOS can make an evener of a 468 with 700hp say 1 or 2 systems activated by a microswitch at the carb to activate both 300 hp systems at the hit of the trottle can you say......... :lol: :lol: :lol: MOVE out of the way...hehehehehe :D :D :D

HIGH RPM 540
 

LIKE I SAID BEFORE I'M INTO MUDRACING NOT DRAG RACING THE RULES ARE WAY DIFFERENT. ONLY THE OPEN CLASS WE CAN HAVE POWER ADDERS SUCH AS NOS. WE DON'T HAVE A OPEN CLASS IN THIS AREA YET. THATS THE CLASS THE PRO RAILS RACE IN , THATS 25-35000 DOLLARS FOR A BLOWER MOTOR . THATS OUT OF MY LEAGUE.....
