nice

Wow, impressive! Great numbers

Your making me drool , Keep us posted ... Ray is shipping my motor home in the next couple days . Its will be spining a Whipple with his supercharger short block & Raylars aluminum heads with Dana exhaust. I'm hoping for somewhere between 700-725HP

I'm looking to do the same thing with mine. So what did it run you after it was all said and done???

Great job Alfred! I keep telling people there is a lot of power available normally aspirated in a Raylar equipped 496 engine with the good parts and good programming!
This just proves what I keep saying all along and it shows that there are options versus supercharging for some nice big power and gobs of torque when the engine package is properly setup and equipped. One ends up with great usable power and the durability and engine life of a normally aspirated big inch 496 coupled with all the benefits of an efi, electronically managed, closed cooled relaible engine package without spending the whole family fortune to get there!

Best Regards,
Ray @ Raylar

Ray - What is the stroke in the 650 package?

I assume the bore is 30 over stock - right?

Torque is now about the same like a 700 SCI from Merc
