Default To Raylar or not to Raylar?

Gents some advice if you please; I am looking at a boat powered with 496 HOs wi- Raylar Big Power CNC aluminum cylinder heads,Raylar's full-roller rockers,BP-206 Max Effort Camshafts and Pistons. Aeromotive fuel system with upgraded injectors. The problem: I really dont need all the power and would prefer a reliable, EZ maintenance setup. The Question: i dont have a heavy foot but i do like to cruise pretty fast, maybe 3500-4000 RPM. Given my preference for reliability I am I insane to consider these Raylar motors? If yes, is it a reasonable alternative to plan on selling the raylars and replacing w stock low hour 496HOs? Inngeneral it seems foolish for someone like me, a non gearhead to buy projects- but I am here for your opinion. Raylars- run from them like anscalded dog or reliable if not beat on? Thanks.

The weak links have been upgraded on those motors. Forged pistons, rods and stock fuel pump. The 206 cam is a 741/525 efi clone. Should be 600+ hp and reliable if built right. How many hours on them? If low hours, think oil and fuel filter changes yearly as only maintenance needed. I would pull and test valvespring pressure every 200hrs and replace as needed.

I have been impressed with the quality and reliability of my Raylar parts. When installed correctly they are very reliable. The horror stories are from guys running the 525 kit on stock hyper pistons. They cranked up the fuel psi on the stock fuel system and let her rip. No idea of a/f ratio and kaboom.

Be nice to them and they will be nice to you. You will be able cruise the same speeds at 3000 rpms with the Raylar engines vs spinning stock 496's to about 4000rpms.

I will probably be in the minority here. If you are looking for reliability and looking to cruise, I would try to find one with stock 496ho's. You should be able to get 1000hrs or more out of it. Won't have to be checking valve springs etc.

I have a similar HO600 setup. Its reliable. If they made it to 130 hours they will make it 500 more. The only issue is getting the fuel pressure right, obviously, its right or they wouldnt have made it this long. Ryan00JT is 100% correct, all the weak points were replaced. The Raylar heads are really nice equipment. Its a reliable setup. I would go as far to say its more reliable than a stock HO because they replaced the cast pistons and stock valve springs - the stock valve springs scared the chit out of me...

I think they'll be plenty reliable, but for how you described your boating goals, I'd say find a different boat, or if you're totally ga-ga over this boat, buy this one, start looking for a pair of stock 496 takeouts from someone moving up in HP, and swap/sell the current motors. Then it's a good opportunity to clean/paint the bilge and inspect stuff that is normally inaccessible.

Before you read this, I say this, ya'll know I am a 496/8.1 cheerleader.

The 496 in stock form is a really reliable platform. I dont claim to be a pro but I have built 3 sets of Raylars and modded the crap out of 2 sets of 496's trying to make HP3 clones. I did however blow them up but it was due to stock pistons, not the stock heads. I have seen issues chasing gremlins from sensors, but were cured after scanning several times and replacing several sensors. In this case, it was bad temp sensors in the exhaust. But, looking at the Raylar as "modded" is a little bit of misunderstanding the platform. The boat community looks at the 496 as a redheaded stepchild. But realistically, its as close to the LS platform you can get as an actual big block (especially when you add the Raylar platform). By using Raylar heads, rockers, roller lifters and upgrading the fuel system fuel pressure regulator I dont see it as modding, I look at it more as fixing the 496 weak points. In some cases such as the pistons, heads and valve springs, very, very, weak points. Twenty years ago, the 496 HP3 ran in racing circles as a competitor and sometimes replacement to the Merc 525. Coincidentally, the in my opinion, the Raylar 600 is a very close clone of the Merc 525 but in another platform. Once upgrading the 496 to a Raylar package, the reliability is as good or better than the Merc 525.

Both 525/600 Raylar
600 Horsepower
forged pistons
forged crank
Aluminum heads
fuel injection
ECU/computer controlled
Cam specs on both are near identical, Raylar is a tad hotter
