Raylar, you made a reference in an earlier post to warranty issues. I assume that a head swap and injector upgrade would void any remaining factory warranty? Do you know the cost of the parts required other than the heads? Nice work!

I would think you could change back to factory stuff if you had a major problem, since no programming of the computer would take place. For all the computer knows, the motor is still making 425 hp.

The price includes everything except for rocker arms. The heads accept the stock rocker arms or you can upgrade to stainless roller rocker arms for $276.00 for the 1.8 ratio or $246.00 for the 1.7 ratio. Hope this answers your questions. Check out the website @ www.raylarengine.com for more information on all our parts.
Thanks,

When we stopped by the booth in Miami we saw the set-up and it was NICE! The display also had the Arizona Speed intake plenum and some upgraded exhaust. Very impressive!
Raylar - are you saying that that only changing the heads with nothing else at all is going to yield 40-50 HP at the shaft?

You bet! Remember the aluminum head has a 10to1 compression ratio versus the stock iron head a 9to1. this alone we found on the dyno so far is good for about 35hp not even counting the head flows about 20% better and faster than the stock iron heads. We are playing with fuel pressure settings and injector sizes now and were hitting over 500 and we have not even had to do anything to the ECM. We are really excited to get our new cams in and our new manifold on. We feel very confident that 575 to 600HP is not far off!

Wish reprogramming the Mercury ECU was easier, but the Motorola unit Mercury is using is theirs and theirs alone. The only way reprogramming will be possible is to wait till the warranty is up, void the warranty or pay big licensing fees to Mercury which they don't appear to be excited about. They are the big boys and they are controlling the market right now! We will keep working on this issue and will hopefully have a better solution soon. Nothing is impossible it just takes better negotiations! Obviously Merc knows that eventually a lot of 496 owners will want to up their performance, just as Mercury has done with the old 502 engines. Hopefully Merc will take advantage of the 496 aftermarket enhancements for the 496 just as they have with the 502 pieces. Everything we are doing is so new that Merc really isn't up to speed yet. Remembering that the big auto manufacturers lost their legal challange with SEMA on vehicle reprogramming may help. Thanks for the positive feedback.

I would think that if whipple could modify the computer, maybe this would maximize what your new heads to. Please post when you have done some more R&D and have more numbers on the Mag and HO.
