Oh, I belive the exuast is about 2 1/4 or 2 1/2. Is that big enough? Ih ave flowmasters.

Sounds good!
What year 440?
The people here including me thinks the old purple shaft cams are outdated. I switched to a new design will make substatial more power.

Tri Y's who is the manufactors of these?
What car is it going in?
Whats the rearend/gearing?

What car model/year?
Mostly whats you plans with the car?
Exhaust? Header dimensions?
Ignition system?
What did you have for breakfest?.........Just kiddin
The reason I ask is that cam selection means alot with things like gearing,weight of the car,stall converter rpm,intake,carb,exhaust and many others.

Honestly you can make at least 30 more horses with a diff cam and may not effect drivabilty any. (may even be better)

Well, it is a going into a 1968 Notchback barracuda, with a 8 3/4 rear end, with a sure grip 3.55. THis car will see street action, racing the rice burners. How hard would it be to pull the cam with the motor in the car? I just dropped it in last weekend, doesnt run yet. THe Tri Y headers, are MAde by Shumacher or somthin like that. THey are a solid header if you ask me

440Barracuda,

Don't pull your cam. The .474 Purple shaft is a great street piece. If you didn't do so already, degree it in at 4 degrees advance. The .474 is ground on a 110 degree centerline. So you should install it at 106 degrees. You will pick up lots of torque and move the peak torque numbers into a 750-1000 RPM lower range, which is what you need on the street, with the gears you are running. It'll take another couple hours of your time, not a couple hundred more $.

Your combination sounds pretty good.
If quality of machine work and assembly is good, you should have
a fine-running street engine.

Give your cam a try: I'm running the same one in a similarly-equipped
engine, and it's been an excellent overall street cam (especially
considering it was likely designed with a slide rule instead of computers!)

On exhaust: don't run anything smaller than 2.5".

What are you running for a fuel system?

What are you running for an oil pan?

Have you calculated your actual compression ratio?

[440barracuda]

Well, THe fuel system, is a 3/8 line, a carter fuel pump, 780 performance holly 780. My biggest concern is exhaust.
I have the 2 chamber flowmasters, and the pipes are brandnew, i got them put on for my 318, and then pulled the 318, and dropped in eh 440.
The pistons are Mopar performance, 9 to 1, and i have 906 heads. I am not sure if that helps any.

Dont touch that engine. That cam is a good cam. I wont be worth it. I see why the tri-y headers now. Your car should fly!

[451Mopar]

Sounds like a good street engine. It should have allot of low/mid range power. It will probbably be fairly easy to maintain and run on pump gas.

[440barracuda]

Are there any little things you recomend?

Trade engines with a primered satellite.

I run almost the exact combo you have (including the cam) in my charger. same gear ratio. only difference is that I have full length 1 3/4 primary hedmans. that motor/cam will get you into the twelves easy, very streetable. idles at 800 rpm all day. I agree that there are better grinds out there, and I am considering one. But, that's after driving the car for 3 years. since you just got the motor in, try it for a while. It may turn out to be everything you want. then if you do not like it, change it. not the end of the world to change it later on.
