Ha- Getrdunn didn't but I did! Passed you just south of Holland.

Tks

Endevour32 did on his way back to IL. He snapped a pic of back of your boat and sent via tx. Needless to say I didn't need to ask who's boat it was. Grand Haven was my original boating stomping grounds. That was over 20 years ago and crazy then. Can't imagine what it's like now a days. Much faster boats and more skin I bet. Lol.

You wont get there with mpi intake but sounds like you pretty much decided its going anyways.IF you have mefi 3 efi and somone who can tune it no reason you cant use the harness and ecu on a real aggressive intake and make 700hp w a 540 bottom end. Im still debating myself what NA motors im building next for my scarab, most likely mefi3 harness/ecus on aftermarket intaked on 540s. Going to play w 500efi intakes and see where i can get them but i know its going to come up short. Going to dyno it to death in search for big numbers when i do it, Smitty

Surprised you didnt throw a tomato at me when going by lol

I would never do that, I find it funny that I keep running into your boat. Thursday night I saw it parked at Canal Street, then Sunday on my way home from Michigan.

Mike, i think thats called stalking lol

That canal st marina is pretty decent setup for trailer boating. Theres not a whole lot in the city for that kind of storage

Not ripe up here yet. Lol. Said your boat looked sharp.

Are you saying he's trying to cheat the GPS ? Mileage and speed ?

LOL. :smile:

Just had a 540 EFI built making 720HP @ 6000 Dyno sheet and video of pull on my Sleeper thread. Everything new, from the Merlin III block to the 320CC Pro Filer Heads. Holley EFI complete system. Everything first class by Mark @ M E R Performance Marine.
Don't by a Holley system yourself unless your prepared to tune it yourself. Leave that to the pros, thats what we pay them for.
My advise.............sell everything you have, pick a builder, and let them decide what to use, instead of trying to make this cam work with that head, and then that intake. Save you a lot of sleep, money and headaches. Turn key engine with EFI will be north of 25K

Your so very right but not everyone can drop 25k plus on builds. With that said if piece mealing it together with this and that and end up making combo changes to achieve your goals that can get expensive also. All depends on self knowledge as well as the trust in others in regards to what works and what doesn't. Common sense can go a long ways.

700 hp can be achieved fairly easily out of a 540 with good internals at half the price.

The best part about this hobby(same with diesel performance) is you can build slowly. You can go balls out and build a 25k 700hp beast... Or piece used parts together and build a 700hp Mill for 1/3 the price.That's what I love about it. All of my buddies I boat with just "order the parts!" I like to investigate... Search the marketplace... Then order... Dang... Half my boat is used parts! But... No payment... Just insurance. Sure I can spend my savings (not a big money guy yet) or max out a credit card.... But much more cost effective to find good used stuff on OSO

maybe he is the guy for cam choice then, seems there has been a few 700 hp recipes lately....

I'm going to let Ray handle mine. I want it to be done right, and have the piece of mind. and with some help (hopfully) from glass Dave... All my spiders can be fixed, and I will be in great shape next season!

I hear ya, wish I never heard of Bob M and did all my stuff with Ray and my buddy Scott, and Joe.

Yea I have read your entire build. I have seen your boat before up at Kelly's, it's a bada$$ boat and sounded good. And I work in North Olmsted and my crew (AT&T) services Olmsted Falls where I am pretty sure I have seen it before a little while back also. Def bada$$

thx bud, probably seen it in back yard here lol

Researching and broadening your mind is fun. So is the the no payment or maxing out credit cards. But you have insurance. Wtf. Ha

I thought you had engine problems because you didn't check the lifter bores for the correct clearances, you just dropped them in and went. Dart blocks are notoriously tight from the factory. Another issue that may have contributed to your failure was the fact that you bolted your new heads on straight out of the box and didn't notice that the valve springs were different. Oh and also the fact that your water temp was under 100 degrees so everything was essentially cold and you ran the crap out of it. I mean Bob is a tool but you have to take some if not most of the responsibility for your failed motor. Just my 2 cents.

Hey lets not fug up Monster12 thread with this BS, take it outside

My engines never go above 100 degrees. Been that way for many many years.

Oh here we go, 1 post trolling!! Lifter notes were checked, non gave me numbers they were wrong, heads out of the box that bob told me were custom made for him because he's a top 5 dealer and Afr custom makes them especially for him, turns out that's false after I talked to afr myself... As far as temps? Well I been running the engines the same way for many years, funny as soon as I delete bob m from the recipe I have had 47 hours of trouble free use, even though bob completely fukked up the combo specs and absolutely dropped the ball on my cams, garbage junk...

Go back to the rock you came from, is this Brian? Kevin? Hmmm ...

1 post, hmmmm brian? Kevin?

I made my response post, not posting again about my builds I am honestly trying to learn what can I am going with next, even if there is a head change too...

Let's get a beer one day, I love in Olmsted falls... Pm me

I think the 741 cam is a bit light for a 700HP 540ci.

Something to keep in mind when reading the internet, and discussing power numbers. Everyones dyno is different. Everyone dyno's in different forms. Meaning, the guy who dynos his 540 in full marine trim, with some GIL manifolds, and that combo, might make 625HP on a legit dyno. A guy who dyno's with some big ole 2.25 race car headers, no accessories, might make 675hp. The guy making 675, makes fun of the guy who only made 625, even though in reality, they are making the same power once installed in the boat.

I dyno'ed my previous engine combo, using 2.25 car headers dumping into a 6 inch flex pipe, no accessories. New combo, dynoed with accessories, my stellings headers which are smaller diamter, as well as marine headers (flow upwards instead of downwords), my tailpipes which are 3ft long with 4"ID tube, on a totally differnt dyno. When comparing my dyno sheets, my new combo shows to be making 30hp less than the old combo. However, my new combo, is actually going FASTER in the boat. I added 250lbs of stern weight with new combo, and on paper it shows 30hp less, but, the boat tells the real story. Esp since I didn't change props or anything else.

Thanks Joe for referring to post #2... lol

How did you like GH?

true, one thing that makes me feel "ok" with my weak numbers is they were with my Stainless Marine exhaust, a charging alternator and sea pump, I don;lt think many dyno the way we did at Ryans... that puts me approx. 660-670 hp in my eyes, not bad but certaintly no home run.

I liked it there. The launch ramp could use some longer docks, but other than that, awesome little town. Would like to get back up there when I have some more time to explore town and what not. We got in the water friday evening, got situated in our slips, grabbed some dinner, and crashed. Saturday , took a quick walk thru town, ran the boats up to Muskegan, dropped anchor for a bit there, ran back to GH, grilled some dinner, and crashed. Sunday ,boat ride to Port Sheldon, anchored for a bit, then back to GH, then loaded up and headed home around 3pm.

I would like to check that out I think, let me know if you go again ..

You barely scratched the surface. You have to come up for one of the WMO runs. It's a great time.

Sweet I definitely will.

That boat is even cleaner up close! Out front of alley cat on the east bank, sounds amazing! Came to introduce myself... Buddy (orange shirt) said you would be back in a little bit. Love that boat.

Thx bud! Great times!!
