why risk all those great parts in a stock block? if its a true 790hp the block will not last long. I'd look for a race block and go from there. the cheapest part of your engine I'd bet is the stock block ..LOL
Yes I would just order the 35 spline axels and spool,better safe than $orry.I have a feeling my gears will be next to break(bought new)I hope your also buying new race gears?Here,s a pic of a 25 inch 30 spline race axel from STRANGE.Running behind a 500plus HP SB.I was wondering how much power a 30 spline 8 3/4" can handle. I was just about to order a new set of Moser 30 spline axles for my new 410" build(close to 600 hp), but I wonder if I shouldn't just get a set of 35 spline axles & matching spool, just to be safe???
The heads are 2.08 valve W5's that peak flow 325 @ .700 and the lower lift numbers are really good too. The cam is a crane roller 276/.727 and 283/.727, net lift at the valve is .698/.717. You can see how much the pushrod angle affects the actual lift on the intake as both lobes measured the same.
I know it's just a sim and they may be generous but when they made 650 HP with that cam in a SS 340 it makes me think. Iron heads, stock size valves, and single thermoquad on that motor plus I have another 44 cubic inches so it makes me wonder. I've got a good bit of money invested in this block now, it's been bored and honed with a plate, tall filled with hardblock and a Hughes main girdle on it. I never really dreamed it would make 700 HP, which may be closer but I have to think now that it will do better than that.
I'd love to put it on a dyno but I don't know if I can swing it right now. Work is slow and my funds are drying up faster than the water in a Japanese nuclear reactor.
It will go together and make some passes so we'll see what happens.

800 hp...:shock:
what cyl heads for a small block can support that kinda power...???
is that intake sheet metal ?
With what you have for heads, I'd be very surprised to see that hit anything more than around 650, depending on the mid-lift figures. You need more duration to really let the heads work and get big numbers. You also really cant compare to Stock or Super Stock. They are an entirely different animal. Put it together and dyno it. Then worry if needed. I really dont think you'll need to sweat it much. (not meant as a cut, just going on info provided)
