depending on who does the motor...you could expect upwards of 400RW.....

Depends on Compression Ratio also. Big difference between 8.5:1 and 11:1

I think with that cam "it's the same as the E cam rite" You won't see over 360 rwhp. Also what kind of dyno are We talkin about? When You get it finished take it to the strip and get some real #'s . What are You hoping for dyno & 1/4 mile, or is it a street only car?

The heads are AFR185"s w/58cc and im not sure but i think the Ecam eqiv for powermax is the 2040. this car will mostly be a weekend car.

Good so it is bigger than the E? Sound's like it will be a great weekend ride to Me. How close is it to completion? Keep us informed as it's alway's good to keep up on different combo's. Do Yourself a favor and put some Mickey thompson drag radial's on it especially since it's just a weekend car .

ok this is just a estimate to my knowledge......
190rwhp stock+ afr heads ~ 250rwhp

Highly doubtful you will see anywhere near 420rwhp with this combo unless the compression is pretty high.
I would guestimate 350-375rwhp w/ 9:1-10:1 compression.

i agree with the 350-375rwhp... unless its a crazy high rev engine and comp

With a 15% drivetrain loss You are talking about the engine producing 450 flywheel hp wich is 1.3X hp per square inch "I am going with Your low figure by the way" which is'nt going to happen with an E cam that will be done around 5800 rpm & 91 octane . Sure with some victor junior head's and a custom with some higher octane & high compression He could put out some of the #'s You are talking about. Dyno #'s are pipe dream's for the most part. I have heard 500-600 rwhp blah blah blah and see a low 12 or high 11 @ 115-118 and know that dyno #'s are very inconsistant at best & especially when You are comparing one dyno to another. On a side note why not go in expecting less then be stoked when they are high, rather than expect great #'s and be dissapointed when they are low . Hope gercolla 1 get's what He want's out of the combo! Let us know how Your tuning session goes man.

No N/A 331 around here makes 400RWHP on an EFI motor with pump gas.
The highest HP pump gas EFI setups around are 2 347's on this site making 442/466RWHP. Most good N/A 347's make around 380RWHP.....most good N/A 331's 20+hp less than that. & That's not with a smogable camshaft or catted exhaust.
You'll be lucky to make over 1RWHP per cube with the setup listed.
Typically 1RWHP per cube takes 10:1 compression, good components, & peak HP at 5800-6000RPM.
The above 347's are making between 1.27-1.34RWHP per cube & run large ported heads, VERY large agressive camshafts, 11+:1 compression, large off-road exhaust, valvetrain modifications to keep things stable at high RPM, & low drag on the accessories (electric fan, water pump, etc) & shift at the track around 6800rpm.

Here's how to build one: http://www.fordmuscle.com/archives/2005/10/BuildersNotebook/index.php
*Note* With a little more compression & a camshaft swap this motor ended up putting down 442/395 to the tires. With an electric water pump 450RW is in reach.
Again, this is NOT the norm. The other 347 that put down 466RWHP is very similar in combination (more compression, bigger cam, smaller heads, larger TB, electric water pump, etc). When it was dynoed it was the highest HP N/A EFI 347 in the country running pump gas. I'm sure someone has blown away that # by now...

347 might make a little more power but when You are using a small outdated camshaft You will never get the elite #'s. Now I am not saying it would'nt make some good power and be a fun street car either. You don't have any room for error when You are N/A, now forced induction is a great bandaid that can overcome some of the mismatched component's in a combo.

You have to take dyno #'s with a grain of salt. I am sure if You went to 5 different dyno's You would see AT LEAST a 10% difference between them so for a 300 rwhp car that would be a 30 hp swing. Plus peak hp & peak tq don't alway's tell the whole story. Compare a 450rwhp civic againt a 07 shelby cobra's dyno graph and they will both make the same peak hp but the usable hp and tq is night and day between them! For Me You take it to the strip and prove Your point & tune on the dyno. Dyno #'s = internet racing, both are pointless. I know I am not telling anyone anything they don't know just putting in My input .

I'm OK with the numbers. Going in to the dyno tests I wanted to see 330/360, and came up short on the HP. I even switched to 1.7 rockers to see if there would be a gain, but there was no change. I bought an RPM2 intake to replace the Explorer setup, but was too lazy to port it and try it out. I think it may have been worth a few more horsepower, but honestly I don't care anymore. If I get a wild hair up my ass I'll put a reworked version of it in my 67 and make some better #'s.

BINGO! the car runs hard, and that's all I ever cared about.

Horsepower = (Torque * RPM)/5252
TQ tells the true power output of a motor. Horsepower is simply calculated from torque. If you build a low RPM motor, you will ALWAYS have more Torque than Horsepower.
An N/A 331 making 351RWTQ is damn good IMO. Is there room on the table for more Horsepower? Yes. Swap out some parts & you can expect more HP & possible the same TQ, swap out other parts & you may be exchanging low end torque for higher RPM horsepower.
In the 305/351 example above, a cam/intake swap & a check of the exhaust to make sure there's no restrictions & the combo could easily pick up 20+hp without losing too much torque. Will it lose some TQ? Yes, at low RPM it will definately lose some TQ, but it may end up peaking around the same (351RWTQ) at a higher RPM & therefore make more HP.
EX: A motor making 350RWTQ at 4000RPM is making 266RWHP at 4000RPM. A motor making the exact same 350RWTQ at 5000RPM is making 333RWHP at 5000RPM. A motor making 250RWTQ at 7000RPM (100 less than the above example) is making the same 333RWHP but at 7000RPM.
Your next question might be: 'So, which setup is faster?' That is a whole other ball game! In general, a heavier car will respond better at the strip from more low end TQ. A bike will run faster with more HP at higher RPM's.
It's all relative... Don't assume that because it makes a lot of TQ it will make a lot of HP. It's RPM dependant.
