Need help with new combination

I hope this is in the right area!

I need some help a starting point for a New blower/cu in combination.

Here is some specs with most all parts being new.

New Enderle pump 13.0 flow at 4,000 pump belt driven at 5% over because of pulley mix ups.I believe this will only let the pump get fuel a little sooner as I have seen no difference with flow on earlier combinations.

Bird injector with square barrel valve set up for port nozzle feed and 6 lb idle poppet.Port poppet set at 20 lbs. Do I really need a Nitro Valve? Jim at Enderle said no.

Alcohol will be the fuel. MSD 7al3 soon to be changed to MSD 10 plus. Crab cap dist with crank trigger.

531 cu in tall deck BBC 4.600 bore X 4.00 stroke flat top pistons
Dart 360 heads flowed to 385 128 cc combustion chamber
Lunati blower cam #50236 specs' .758 in .739 ex 287in 295 ex at .050 112 lobe separation 110 center line.

BDS pent roof cast aluminum blower intake.

Mooneyham 14:71 blower "Not a hi Helix" but with a Delta/Retro ? Bottom pie shape built into the blower with only a few brake in runs on it.

I want to be starting with 42/30 14mm belt combo that can be sped up with top pulley at a later date.

Main feed line is 1 1/4 to pump and An10 to the hat. An 8 feed line to ports.Fuel tank is in the front of the vehicle high enough to feed pump.
Vehicle is a 2600 lb door car with Dedenbear 1:76 PG 10 in TK Converter 4,000 stall and 9.5 4:30 Rear gear using 16X32 MT's.

I use a 4600 rpm two step,and return fuel at .086 when it is activated.

I use a transbrake and a air controlled stage system. 2.250 Zoomie headers

My questions are::::: 1..What is the total nozzle area needed for this motor?
2.. What should the port to hat ratio be.

Has anyone run the front discharge blower on a BBC?

I am concerned there will be a problem with the front discharge feeding the front two/four cylinders to much fuel/air.

I had a friend tell me he had his system flowed and used only hat nozzles and it was working fairly well. He knew there was horse power he was missing without port nozzles. He was told to split the hats and ports 50/50 and when he tried to run it he burned up the front cylinders. After several terrible mistakes he ended up with 58 nozzles in the front with a stagger back to the rear cylinders of 36/40 to get the fuel distributed.The people who flowed his system did not tell him about the stagger and it cost him time and money that I don't want to waste.

I have run open bottom blowers with staggered hats and high speed lean outs but I am really scared of this Pie shaped bottom blower. I am in the process of figuring out a way to move the pie discharged blower back but the windshield and other factors will have to be changed first.
I have aftermarket and custom barrel valve and poppet setting tools that lets me control settings on the poppet pressures.

I have studied the flow sheets and fed in lots of numbers to them but I would really like a better understanding of the Port to Hat Ratio and how to get the desired Total Nozzle Area for a motors Cu In in relation to different bore and stroke combos.

EXE...large bore/short stroke OR Long stroke/small bore.Would the formula for std injection motors using Displacement X .00021367 really be the same? And what formula would be good for a supercharged motor?
Would the formula need to be modified for higher and lower compressions ratios.

I have put in a pump saver feeding the hat,and a high speed as needed when I get a better starting point. And suggestions?

Thanks for any info. I usually don't need to ask very many questions as I have watched this side for a long time and can usually search for my answers .Maybe just can't see the forest for all the trees as I am very impressed with the knowledge available here.
Sorry for such a long post ,,,,,Chuck

 

luv truck

Chuck, you ready to get the hot rod back to the track? I can give you the tune up as far as hats and ports,main jet we run if you want. Not saying its what u need, but worked for me. howard

 

Howdy,
I've always had good luck with Ralph & Spike Gorr, give'em a call & they will get you set up. They're easy to deal with & their reputation speaks for itself & he usually sets you up pretty fat so you're not going to hurt anything right away.
good luck.....

 

im running the same basic set up . im kind worried about my fuel system and how it will all play out . i would love to see where you ran your set up so i could use that as a starting point

 

this just stuck out to me, so i figured i would mention it. i would use a #8 line from pump to barrell valve for feed line, i think #10 is too big for what you are doing. just my 2 cents
