How much power

[scott melancon]

I am currently putting together a 406 and would like to get an approximate amount of HP I will have. The following is what I have.....

MDS ignition
Duel feed Holly 750 carb
Team G Intake
Brodix Track 1 heads (222cc runners, 68cc combust, 2.10/1.6)
Crane Gold roller rockers with girdle
Forged steel 4340 Eagle crank
Eagle H Beam rods
Mahle 13-1 11cc dome pistons
630 lift mechanical roller cam
Lower end all ballanced.

Any information would be appreciated. It has cost me a lot of $$ and I am anxious to see what it would do. I can't wait to get her on the track but it will be a while from now as I am making mods to the 82 camaro.

Thanks,

Scott

Scott,

Do you have the part number for the cam or know the 050 duration and lobe seperation?

[scott melancon]

Crane Cams
Part # 270-118751
Adv Duration: 284/292
RPM Range 4000-7400

This is the only piece I have not bought yet. I was going by some recomendations made by a good friend of mine. Thanks for your help.

Hi there! what I came up with is 692fpt at 6250, 905 hp at 7250rpm. I use 110 lobe sep. and 110 oct. fuel. duel plain intake.
Have fun.

psychoward,
What did you use to figure this out? Seems extremely high or else i have some serious chasis and cage work to do. I was only expecting around 600 or so but it was just a uneducated guess.

Thanks,

[scott melancon]

Anyone else out there have an educated guess. Any info would be much appreciated.

Thanks,
Scott

Guess Not.
I will have her ready by fall/winter. I guess the track will have to tell. I will post results.

I get 575 HP at 6,000 rpm, 560 lb-ft torque at 4500 rpm with high flow single plane manifold.

With the compression ratio and heads, with that induction package and a cam that will obviously work in the high rpm band I am picking this is a circle track motor, so probably around 520 to 535 HP. Oh nd with that roller cam and that much lift your spring pressure had better be a minimum of 200 Lbs seat pressure and run a rev kit as well to keep those rollers on the cam lobe at all times.

That sounds an awful lot like my old set-up. If I remember right the dyno numbers came in real close to what Kitz said.

[scott melancon]

Thanks to all for your input. I was hoping to have between 550 and 600hp so your estimates are close to my goal. I will post my track dyno results when that ever so elusive time comes.

Thx
