I'm in. Pick a dyno. Why limit it to 5000rpm?

I think most people out there can relate to a NA 454 production based engine. What do you think? How about my dyno.

Sure, it's a little on the small side for a performance boat engine but ok. Why do you need to limit your dyno shoot out to 5000rpm. Any well built 454 with factory internals will turn 6500 rpm reliably with very little effort. Is it because your peanut heads fall on there face after 5k? I guess you're pretty proud of yourself for making decent power with peanut heads, well obviously you are because you post on almost every forum on the internet, but really who cares? How much work goes into those heads vs. bolting on a set of AFR 265's? I'm sure it took considerable skill to get that combo to work, but how is it relevant to the average performance boater? Are you selling these heads cheap?
Anyway, back to your dyno challenge where you said nobody ever steps up.. I'm in. You wanna run 454's? No problem, I'll put out of the box untouched AFR's against your magic peanuts any day and stomp them. No magic there, it's been done many times. Just pick a dyno other then yours.

Damn, I'm lovin this a DYNO SHOWDOWN!!!!

5000 RPM was mentioned in this thread, theres no way a 236 head will run with a 265 AFR, and I never said it would. I think Westec would work just fine for a dyno facility. I think at this point you should come up with some guide lines, I will be contacting you this morning. By the way, my peanuts ports peak @ 5800 RPMs with a 228 @ .050 hyd flattappets, not that it matters. 6500 or more RPM limit will be fine with me, thats up to you. To answer your question: I just tried to point out what Ive done with 236 heads, I think they could work fine on a 5000 RPM 454 boat.

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

Personally I would like to see you use Dave's dyno or similar that can better recreate the true envirornment of a marine engine! Besides that, Westech's dyno runs always read much higher than anyone else dyno. Granted if both engines are dynoed on the same dyno big deal. The problem comes when other people try and recreate a particular engine and can't hit the numbers posted by westech's dream-o-meter! IMO being able to run with wet exhaust or at least dry to the tip is where skill and knowledge comes to play as camshaft reversion is a real killer in the marine world! Otherwise any old car engine would work.

Both engines would be tested on the same dyno, I would disagree on Westecs numbers being wrong, infact I think we could bring in a dyno expert to calibrate the dyno before the tests.

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?

454 dyno showdowns.....Awesome!!!!!
