So I am rebuilding my 400/512 and going to, if I can afford it, put a TorqueStorm on it. I have it all apart, and new bearing and a few other parts are on order already....

Its a 440Source 400/512 with a girdle and Indy 325 heads with 2.19 intake valves...

So I am going with 10:1 compression, and shooting for 7psi boost...And street and drag it...

I have another blower motor built by a friend and was wondering if this same cam would be a good choice....He said it made real good power.

In my experience, yes that cam would work.
Power band is probably fairly high.
What gear/converter etc ...do you have in mind?
I run a small Roots blower and it sees 7lbs.peak.
My cam is 236/242@.050 .501 lift
110 c/l.
Has gone 10.48 @3,600lbs 440in motor ,3.33 gears ratio.
Shift at 5200/5300.
Again my opinion, 110 C/L is the best compromise.
I've tried 6 different cams,110..112..114...
110 gives best idle,cruise,response and ET. In my car.
I know there is power left on the table with a "regular " cam.
But the blower is going to rule the max power more than the cam.
Wrong cam will just hurt lower RPM torque. and effect idle quality.
Boosted stuff will run better under-camed. ,,,Max EFFICIENT blower speed is the ceiling..not the cam...

Gearing is 3.73 with either a 31x16 cheater slick or 315 drag radial.

Convertor is a blown A gas 9.5 or 9.0 from ATI

Weight will be 3100 car + my 250....

How fast/ET are you shooting for?
Blower speed will factor in as well.
I'd ask a cam shop...Comp etc..to ballpark what you are already thinking 🤔

Shooting for 9.50 or quicker...

Car should be right around 3100 plus my 250.....With the big Hemi its 3204lbs...And that Callies block is like +300lbs..

I’ll throw in my .02…..

My impression of the TS blowers is they aren’t terribly efficient.

Putting one on a 500+ cube build with bigger heads and a long duration camshaft is going to require spinning the blower harder to make the desired boost.

For that combo I’d run a shorter cam(than the card in the pic).

That's been my experience too...don't overcam...

Just for reference, that cam is currently in a +.030 440 I have, that is not stroked....

If you already have that cam then sure, it will work. If you are going to buy a new cam then I wouldn't buy that particular one. I don't think you need that much split with a blower since you'll have more cylinder pressure.

So the 259/270 split is a bit much?

Most of the cams I look up on Comps sight for the 440 have a pretty big split. I hate their web page though, I could not find any cams for boost. I am figuring for the street, somthing right around 260 or less would be nice. I will call one of their reps and see I guess.

That is the current cam in my +.030 440 that I will probably put a roots blower on someday....It has the TF270 's on it. This engine I need a blower cam for has Indy EZ 325's upgraded to 2.19 valves. Figured they are probably pretty close as far as flow...

The best cam that Dwayne and I came up with for my TF head testing was a 264/268 solid roller. That cam made close to 800 hp on a pump gas 470 inch engine with TF270 heads and a heavily ported intake. That was NA.

That's a bunch...And I wish I could get that out of one of ours. Is that the one you did the dry sump on?

Best we have done is right around 720hp according to the Wallace calc. with this combo NA ...at 512 cubes...Not exactly sure what we will get with a TorqueStorm at 7psi, but I think I can have less cam and compression, and gain a little drive-ability, but make really good HP...

7 lbs should add about 150/175ish HP..

Agree 100%
