850/900 hp

I am at the design stage of building a new engine for the Daytona.
What would your build consist of. Money is an issue but do want good parts but not overkill. I will assemble the engine myself after all of the machining is done by a local shop I have used for over 20 years. I have built performance engines for 35 years.
It will be natural aspirated, roller cam, tunnel ram? F.A.S.T.
electronic fuel injection.
What cubes - 598 or 632?
Plan on using a tall deck block.
I have dry exhaust so cam overlap is not an issue.
Would you do the firing order swap?
Thanks
Steve

So you're not worried about reversion, correct? No chance of it at all, ever?

Hard to get reversion when your exhaust is dry to the tips of the two foot tails.

I would go to offshoreonly.com there are alot of motors on there way over 1000hp good luck. buy it drop it in pull the rope.
