So, the 310's should work good on Dales 540's if he goes that route it seems... lol

You obviously dont understand that dry jacketed tails , can be muffled in many ways.

Lets move on, you failed this course. Should we try something more simple for you?

Heres one. What colors are navigation lights ? Red and green, or orange and blue ?

Sorry, I understand them perfectly. Dry pipes are not ever going to make only 90dB.

but hey, you don't get it so now you want me to explain nav lights to you. BTW, you missed one of them, so the answer is none of the above

[QUOTE=MILD THUNDER;4376477]Lets see here Joe- Seeing that you know what parts are in my builds please list the parts? Please list what parts are junk, what are used and what is new? The only person on this site that know's anything about my builds other than me is Getrdunn, as all the work was done in his shop last winter.

As to the Reeds cams you sold me- Yup they were junk- They made no more power than a 454 mag. Do you remember when you were selling me those wonder cams that you also tried to sell me a set of Weiand x-celerator intakes? LOL- I sure do and I told you no thanks because they were worse than the RPM intakes I was using! Also- I think you are a bit mistaken as to what I paid you for those cams and it sure wasn't $75 each, but that wouldn't be a good story if you posted the real price. As to the lifters- I never bought any lifters from you, I bought some lifters from Tkach that were supposed to be Morels. I think I paid closer to $300 for them and come to find out they weren't Morels but most likely Cranes. I sold them and never installed them in my engines, and I ended up buying new Morels.

Now you claim I have Bob's cams, AFR heads, and raised the compression in my engine. You are a crazy dude, where do you pull your info from? What part of all things being equal other than cams do you not understand? I replaced the Reed cams with a NEW- not USED pair of 741 cams. Compression is the same, pistons the same, carb the same, exhaust the same, everything is the same! With that change and that change alone I gained 4 mph at the cost of $650.00. And yes- boat idles just fine at 700 rpms. Oh- hold on- I did replace the timing chains so maybe I picked up 1 mph there!

As for me not affording new cams when I bought the Reed cams, sure that was true at the time- I was working on my masters degree and money was tight, so what! IMO, spending money on my education is a little more wise than spending money on my boat!

Thanks for calling my Formula junk, which it isn't- At least I didn't take vinyl spray paint and paint my seats because I couldn't afford to have my seats upholstered. All the vinyl in my boat is new and was purchased from McLeod, it's about as good as it gets, certainly better than a can of spray paint! I also believe you are running heads that were bought second hand, as well as those mighty blowers you bought second hand. I'm sure a lot of your boats bling parts are second hand parts. So before you start slamming people for buying something used, you better look in the mirror! I find it rather interesting that you slam people for doing for the same things as you have done/do. There is nothing wrong with saving a buck or two, but I guess now you are too cool to admit you too buy used parts!

[QUOTE=endeavour32;4376856] You still wanna keep making up lies? Do I have to dig up the paypal invoice and shipping info too?

Oh you had RPM intakes? You told me YOU wanted weiand intakes to replace your stock mag intakes, and I simply said a buddy had a pair for sale!!!!! Another oso liar.

Sure sucks to have proof when people try to make you look bad..... I love when people lie and the other person has proof....

Are you a moderator on this site ? If so do your job and stop the BS caused by these few that keep stirring the pot for reactions (same 4-5 that you stick up for) and I will not have to jump in..........SIMPLE ENOUGH!!!!!!

Yea, did you know the scorpions are better than the crane rockers ? Hmm

:helmet:

This is a good point. With a car, 20hp is a significant, seat of the pants gain but in most marine apps., especially these big multi engine boats, 20, 30, even 40hp really isn't going to set the world on fire. Making a 20hp difference is usually fairly easy on most mild builds but trying to get 50+ with our example; a ~700hp pump gas 540 living in the <6000 rpm range pretty much isn't going to happen without a blower or more compression and even then, you're still going to need to increase rpm to the max of whatever your combination will allow.

bck:
I don't care what heads, intake or cam you try to use...you simply can not force more air/fuel into the engine than it's going to take on it's own but for one exception and that's with a tunnel ram and two carbs. Tuned, equal runner lengths, a common plenum and the charge inertia factor will make more power because of increased VE. That's about the only "bolt on" improvement that will make any significant power increase without changing compression, displacement or rpm. Bigger heads will only slow down the airspeed through the port and that will hurt VE (cylinder filling) which is what makes power. More cam might make a little more peak power but not enough to be worth while and will hurt the average below peak and for these big boats that's not necessarily a good thing.

Lets see Tim you have over 7000 posts and 6999 of them are about YOUR 2 boats that have so many failures by your own hands over the past 5 or so years I can't even keep track of them. Now that you have got 1 of them to run for 10 hours you are all about giving advise................BRAVO YOUR THE BEST.............I will PM you later about a new build we are working on so you can teach me the right way.
