not to be a jerk, man--but you are bragging about 408 cubes and a blower making 550 hp?

[fairmont356]

Newbie...
I have a SBF with Jr heads, in NA trim it makes about 450. With stock junk bottom end.....so

[Blown331fox]

331 cubes here making 554 rwhp...someone give this man a cookie!!

[mikeheusser]

Yes, 550 HP or more WITHOUT the super charger, I did not dyno yet just built.

[Red5.0]

That sure is cool to brag about yourself. Go to the track and get some numbers.

[SSKiller]

Thats a wussy cam for a 408" motor man..... I got more lift than that in my lil 306.... put a real cam in there and I'm really hoping you don't have the BBK 1 5/8" 302 headers on there with Victor heads... you'll be lucky to make 450hp. You need no less than a 1 7/8" primary with a big inch motor and a race head.

[redrumpony]

Everyone has to start off somewhere. When I started out over twenty years ago, I was the perfect example of " the bigger, the better it must be syndrome". My '67 mustang ran low 15's high 14's because nothing was designed to work within the same parameters.
Now look at my car!! Massive amounts of power everywhere in the power band!!! Oh yeah, I only used 1 3/4" headers and a conservative cam with good flowing heads. That builds something called TORQUE. I wonder what torque is good for? (refer to avitar to your left) James

[Class85GT]

Power is going to stop at 5400rpm's, if not less. I can't see anything over 400 HP at the flywheel.

[redrumpony]

What's the duration of that Lunati cam? Are the headers 1 5/8" or 1 3/4" and what size is the collector? If it's 3" and you use a 3" exhuast system with a good muffler, you should be alright.
My cam was 244 in 256 ex @ .050" lift with lifts of .595" on both in and ex on a 112 LSA. It pulled hard to 6500 RPM's ran 10.40's at 132 MPH. James

[mikeheusser]

First off the cam is a nice cam at : Advertised Duration 276/286, Lift .536/.536

Second of all, my headers are 1 3/4 primarys.

And no, I am not an idiot like you.

[Blk88GT]

LOL

This thread is hilarious.

hOW CAN i POST A PIC OF MY CAR.

What's the duration @ .050" ? Who ported your heads/intake and were they flowed? The cam could be bigger, I would probably use one with more duration @ .050 because I'm guessing that cam is in the 220-230 range @ .050" lift. You wouldn't want to go less than the high 230 range @ .050". James

[mikeheusser]

James,

The cam @.50 is 218/228, it also likes nitrous. By the way I also know that pressing alt+f4 closes windows, nice try CDP.

James, how can I post a picture of my car.

Thanks.

I had my brother post mine , so I could not tell you how.

As far as the cam, that thing is incredibly small for a 408. It is relatively mild even for a 306. Your intake isn't matched very well to it. You'd be better off by selecting something with about 20 to 30 degrees more duration @ .050" lift. Those motors produce tremendous torque, but you'll have no top end power with that cam which would be better matched to a dual plane intake. I would switch cams; just trying to steer you in the right direction. James

[moparmanjames]

I agree that the cam is much too small for what you want to do.
I think Car Craft used this cam on a "build your first engine" article on a 302 with a holley street avenger top end and made 352 hp.
On your engine with the nice heads I'm guessing 460hp@ probably 5500 due to the wide LSA, 112, but lots of torque down low.
Other than that, it sounds like a nice build.

[mikeheusser]

Thanks for the cam lessons, although my car runs very strong, she has alot of torque too. Can you tell me what to expect after adding my Paxton Supercharger with 8 lbs of boost.

Thanks again ))

[onesillynotch]

you tell us..aparently you are teaching us a lesson here

lol @that killer 408 cam

btw whats the compression of this beast..i mean you plan on 550 hp on motor then going to blow on it..

also you think a paxton for a 302 with a 8# pully is going to give you 8#s on a 408

Have you taken it to a dragstrip to see exactly how much power it truly is making (i.e. trap speed in MPH)? You might be suprised at how much power you could gain by going to a much better matched cam for your combo without losing any bottom end or midrange power.
My car would spin the tires in third gear up to 70 MPH on the street. I originally had a 230 in 238 ex @.050" lift cam on a 114 LSA which did'nt have the power up top I wanted. I switched to a larger cam 244 in 256 ex @ .050" on a 112 LSA and picked up 2.5 tenths in the eighth without losing any power down low. My sixty foots consistently ran in the mid 1.30's with a best of 1.315; all on the motor, with a stock T-5.
408's are big motor and a cam that may act wild in a 306 will be tame in a 408. Basically, what I'm trying to say is you would definitely benefit from a larger cam. I'm not trying to blow smoke up your arse!
As for the blower, same thing. They can only push a certain CFM of air. If your motor is already pulling in let's say 60-70% of the CFM rating of the blower naturally aspirated, the blower will not be able to support the CFM needed to produce the rated boost for the unit. Boost is a measure of pressure. Not to mention your combo is carbureated. James

Dude, before you start bragging about real power and how kick ass your notch is going to be...............take it to the track and work the bugs out first. Also, I hope you're talking 550 @ the wheels......

[Blown331fox]

550 HP from a 408 with a 536*cam...should be around 13.5 :1 compression with 116 octane gas...yea throw that blower on it and get back to us with some "REAL POWER".

[moparmanjames]

I ran your combo through my engine analyzer and came up with :

495hp@ 5500, 485ftlb@ 4500.
I used stock rod length of 5.956 since you didn't specify and a stroke of 4", bore 4.03", also I guessed at 10.5:1 compression ratio and stuck a 900cfm carb on it.
Those are very good numbers for a small cam, indicating excellent head flow.
I can't figure out this supercharging yet but I'll guess with 8psi on top of that you'll push over 600 hp at the flywheel.
You'll need good gas though, if the compression ratio is that high.

[KillaCoupe]

ET makes a car fast no a dyno sheet

[moparmanjames]

KillaCoupe, E.T. is the time it takes for a car to get from point A to point B, it's not what makes it fast.
A Dyno sheet is what a Dyno makes when measuring an engines torque. It is then converted to horsepower in the formula
HP=TQxRPM/5252.
Then you get the Horsepower curve along with the Torque curve.
This in itself isn't worth much, but when combined with other variables such as vehicle weight, gear, tire size and traction limits, transmission efficiency, converter slippage and stall,
Barometric pressure, humidity and temperature, one can make a fairly accurate guess as to how fast a car can E.T.

[moparmanjames]

Okay, I put a Paxton NOVI on the engine with a 2:1 belt ratio on it and a honking intercooler and I got 747hp at 5500 and 714# also at 5500, but even with 100 octane in it, the program still had to retard timing.
I lowered the compression ratio to 8:1 and you only lost about 21 hp with no supercharger and with Paxton it made 724hp and 691# again at 5500.
The program said it was getting lifter pump up at 6000 so you might want to set the preload at zero lash.

[Tinnocker]

The combo in my sig made 600hp at the flywheel with a bigger better matched 252/262@.50 .576/.576 cam .
You will not make 550hp to the wheels with that combo.

[regattacoupe]

If it dosen't make enough power change a pulley.....LOL.....I usually like a cam that about one size smaller than anyone else would pick out but lil 218@.050 isn't enough.....something 230 ish is about the smallest i'd get for a 408. And those vic jr's want more lift.

[MX22Rider]

did i miss something.... 550hp out of a blown 408? theres guys on turbomustangs.com making 550hp on stock 302 shortblocks. Do yourself a favor... run a meaner cam, and forget about the blower.... buy yourself a T88 and then make some REAL power, then after you go to the strip and stomp on it and **** yourself... then come back again and ask us "how do i control my beast"

[KillaCoupe]

my point was i dont care how much it dynos...that measures power big deal if it doesnt hook(work) it aint worth ****

Yeah you did miss something. He said 550 fwhp N/A. With a meaner cam and a Novi 2000, 800-900rwhp can be attained. Or you can set it up for 600@ the tires and it will last a long time.

flywheel hp!!!!! I thought he was talking at the wheels..........you've got plenty of guys on here with 331's & 347's making that much

True, but if traction is your worst problem and your running slicks and a decent setup, your doing good.
