From Nov 28-30, 2011 Harold will be The Master of Ceremonies for the Advanced Engineering Technology Conference, which precedes PRI, in Orlando. I will be attending both AETC and PRI and I have confirmed Alex Haxby, and Tony Mamo from AFR will be arriving for PRI (12/1-3). With everyone involved converging upon Orlando for these events, what better opportunity to crate up both engines, ship them to Florida (at a minimal expense to all compared to transcontinental flights) and dyno them both right in Orlando. We can arrange for dyno time in advance, possibly with Mike Laws who will be hosting the carb Shootout test, or at the Autoshop (former Engine Masters Winner) facility in Orlando. I believe it would be appropriate to provide Harold with appearance funds, with any balance to be refunded to the participants upon payment of dyno facility, fuel expenses etc. Each person I have spoken to has confirmed for this arrangement. The only details left would be to refine the conditions you set earlier in this thread. Bob |

I wouldn't rule out the heads. Heres what a local did with his.
"Mark ran a isky 280 cam 232/565” 9.5cr ported 236 head 454 to 5600rpms 547hp / 580ft lbs" :bsflag: he must have used the dyno at Dereberry Performance Marine. |

I have many times built 560 HP 236 headed 467s with 9.6 comp, its not BS, just fact. My 9.2 comp 228 @ 050 flattappet 467s make 530 HP @ 5800 RPM, (29.92 60 degrees, dry air) with 236 heads, performer RPM intake and stamped LS6 rocker arms. As a side note Im allways open to dyno challenges, please feel free

Why would anyone turning a 454 5000 RPM want a bigger runner than what a 236/peanut would provide.

Well Bob, I wouldnt have any hesitation running one of my 454s at a 5000 RPM limit against one of yours at the same compression and cam profile, but this is the internet, I have yet to see anyone step up, but please feel free to do so. Whats wrong with a good old fashion dyno shoot out?

Anything goes would be more than fine with me also.

Yea, and it looks like it might happen, now if we can just get Madera involved in designing the cam over there on the other side, I think this could be very informative for the boating world. A real dyno shoot out that cuts through the :bsflag:
We can hammer out the fine details but, since this is a performance boating website the only thing set in stone is WOT for at least 20mins on 89 octane, just like in a boat. If you can't do that then go ask for a shootout on an automotive foum.. Thanks, Alex. |

Here's the guidelines: 454, 89 octane, Wot for 20mins, idle @700rpm, full marine trim running all accessories and wet exhaust. We can even use the same exh. manifolds. SM or Imco would work fine for this application. Is that what you had in mind?
Let me know when and where and I'll fly in to help. |

SB, these engines mentioned are are for automotive applications, I couldnt imagine the HP loss with marine exhaust. I test these engines on a SF 901 dyno with 2 inch full length headers into 3 inch exhaust. I know nothing about boats, but was searching forums and found this thread and felt compelled to stand by my dyno numbers, thanks for your interest. But to answer your question, dry 1 7/8 X 36 headers into a top ten shoot out 3 inch center in center out muffler.
