I argued this some years ago and it occurs to me I might be in the same situation here. When someone says "pump gas" I make the assumption that it's gasoline, or a 90/10 gasoline ethanol blend that anyone purchases out of a pump at any quickie-mart or gas station anywhere in the country. Not the "pump fuel" lower octane race fuels that are carefully formulated and bought at the track. So to clarify - where is the OP on that?
Based on 92 octane pump gas with an 8-8.5 DCR.

No this is what you need to buy or build. 700 horse on pump gas without a power adder takes this kind of technology.
 
A R5P7 motor will need a diffent bell housing no stock bell will work with this block your going to need a tublar k member because of the dry sump custom made headers a 6500 convertor is not going to be street friendly you will not find a better motor for sure they a very trick motor make sure to buy one complete because each builder did things different I'd call Ernie Elliot by the time your done with the motor trans front end headers dry sump plumbing lines your looking close to 18-20 k if your paying 13 k for the motor I've already done this build so I know what it takes

that`s funny, I read not a dry sump engine !
 
OK so here is another question:
How does an R5 bell housing differ from an R3 bell housing? Or for that matter an R1 bell housing?
Where can I get dwgs for these?
 
There totally different go over to moparts and look up leon hudson he sells everthing you need for the transmission
 
I'm still thinking more than airflow or block or fitment - the pump fuel as I understand it just won't let happen.

We broke in my 434 on Renegade Crate 98 race gas, checked the valves, made a few pulls to get the jetting and timing right. After all this was done and we had the best results on the 98 we pumped the fuel cell back into a can, drained the bowls then refilled the fuel cell with pump 93. After warming up on the pump gas the first pull was 30 more hp than the race gas. I thought it was a fluke so they cooled the engine down and made another pull, 30 more hp again.

Your mileage may vary.
 
I was thinking a 470 small block on pump gas

You get to a point of diminishing returns on inches if you have a small head. Liking drinking in air through a straw.
No matter the size motor, its going to take W8-W9 or perhaps the new Victor heads to make 700 on pump gas
NHRA pro stock motors are 500 inches. They are only roughly 3 tenths quicker than 900 inch mountain motor pro stocks.
So cubes wont solve many of your issues. Just move the powerband down
 
R3 blocks are getting hard to find so you will have to figure out if your going to run 48 or 59 degree lifter angle short deck or tall deck best of luck on your build

Your going to need something like this to make 700 hp on pump gas
