My point with the RPM's is that big motors like to breath, you may have problems trying to get it to make power that low.
Explain how higher RPM's make it less streetable? With your tall of a tire you will not need a killer gear and you don't have to have a killer stall for high RPM's.

Motors that big can make the power I want around 6,500, with the engine guy I was talking to he said it would be easy, I am most likely going with a 615-622 with a sniper intake and the RFD Edelbrock 24* heads, what I can see those two are the top dog conventional stuff right now.
As far as stall I really don't want to go over 4,000 tops. Cam I was looking at is 279/289@.050 .748/.748 on a 114 lobe.

Baby cam for that big of a motor if you ask me 
It will make around 900hp in a 750 set up right
I would not say those Edelbrocks are the top dogs in conventional stuff either. A few that are better but you pay for it, thats a matter of opinion though.
P.S. Generally you pick your stall based on what the cam wants.

Another one was 284/292 .748.748 on a 112.
Both made peak power around 6,500 and peak torque around 5,500. As far as the research I did from conventional heads, the Edelbrocks with that cc and price range make more power than comparable heads.
As far as stall, I am not going to put something for optimum drag running, it's a spray motor it'll kick *** with 3,500 or 4k max stall.

That changes things.
Not saying to stall the crap out of it, just saying cams need matching stalls.
From what I can tell mine is a 3800 stall on motor and goes to near 4000 or so on the bottle (also based on info from Coan).
My old cam makes peak power at 7k so I would do some research before you buy or decide.

It's not like a small block, even at 3,500 it's going to be over 700 ft torque.

Unless you are getting a nitrous cam (most will tell you to stay away from them unless its on a big shot all the time) then you get a good all motor cam, hence getting a good stall for it that also does not mind the bottle.
Looks like those heads are pretty good, I was thinking of plain ol Edelbrock.... my bad.
If I go the troute I am thinking with the Notch Ill get I bet it will be Canted heads.......
Im sure it would not be very fun on the street but Ill have a fun street car, the mustang will be a 90% track car.

Why not run the 11* big chief stuff? RFD makes a lot of killer set ups people are talking about.
I'm building my motor to run on nitrous, I don't care what it runs on the motor, I'll only be cruising it on the street so if it went 12.50's on the motor and 8.50's on the bottle I wouldn't care. 3,500 stall and I am leaning towards a 2.10 1st gear TH400. I'll have a pretty big tire so I can get away with a little more trans gear I think, besides a power glide on the street would suck.
I'm probably going to get something around 270/284 .714/.714 on a 114, I don't think it'll make 900 hp but even if it made 800 or 825 or 850, it doesn't matter. I may go even smaller. I should need under 900 hp to go 8's, and I'll have my fogger so even with a super mild 598 that made only 700 hp, I'd only have to spray like 150-200 hp to run my goal et. 150-200 shot on a 598 isn't ****.

Yeah 8XXhp is more realistic.
Those are some heads I have been looking at. I know most of the poeple that use them are N/A guys and stuff gets $$$ when you go big chief.
Those are $5,400 plus tax plus shipping BARE.
Get a valve train and inconell exhaust valves, titanium intake valves (both are pretty much a must for high boost) ect ect and I bet you are over $8,000 easy.
Not something I will just looking around for a few minutes then hand over the mastercard HAHAHA.
Not to mention an intake!!!!!!!!! Something tells me a cast intake would choke those heads out.
To think I could buy a nice crate motor for the cost of the heads hahaha

Do some more checking before buying a small angle profiler. 18* would be a better combination head. N2O seems to like more angle.
No expert, so do more checking on the latest & greatest thoughts of the experts.
Another thought, if you're only looking for 8's you don't need as much engine as you are planning.
At 3200 lbs with a 454 block, chevy crank, old *** heads & 150 shot I ran 8.50. Crap 60' on 10" tire.
Build your 632", make it as strong & streetable as you can afford. Throw a fogger on it & your done.
Conventional head, mild compression. Don't forget, the bigger the engine, the less stress & strain the N2O causes.
A 400 shot on a 632" is mild. A 400 shot on a 350" is killer. Just a thought.
What does this car weigh? You might be closer to 7.99 than you think. Good luck.

I'm actually narrowing it down to a 598. 10.200 block 4.600 bore 4.500 stroke with either a 6.7 or 6.8" rod most likely bmf or edelbrock 24* RFD heads or a 615 with a 6.7" rod.
I want to use a longer rod for street use, but also have enough room for a good nitrous piston, 632 has too much stroke to do that.
Main factor will be using a cam that can be mild enough for pro street use, then using the nitrous to make up the difference. I honestly think I can make 800 hp on pump gas with a moderate size roller cam.
Either way I'll get it figured out, there are a few guys helping me select the right stuff to meet my goals.
I don't know what the car weighs, but other guys with similar BBC tall deck stuff with full body and floors are around 2900-3000. Mine has the entire floor removed, most of the shock towers, everything in front of it, plus it's lightened up a few other places. I think I can maybe get it under 3,000 race ready, I'm 200 pounds so I am shooting for 2,800.
That should only take 800 - 825 hp or so to break 8's, If I make 800 on motor and spray 300-400 that's 1100-1200 hp should make it well into the 8's especially with a 4 link and 32/33" tall ,15/16" wide tires. I'd think it could go 8.20's and 5.20's in the 1/8th.
