Hi! I have that engine and i would like to know couple things about it: How much power it has? 7A heads, cleaned and sanded etc, headers and howard cam, 204/214 @ .050 and 750cfm qjet and olds _ 16 _ intake. ? Engine builder says 300hv and 500nm, true? Is that good engine? Mild cam? Second question: _ 16 _ intake or edelbrock performer which is better? Engine is on light a-body cutlass.

OK, 500 nm (about 370 ft-lb to the rest of us) is probably about right. Are the heads 7A or 7A? These are different castings. The 7A heads were used on the 1985-90 roller cam 307 motors and have tiny ports that are not conducive to building horsepower. The 7A heads were used on 1972 350s and are perfectly good small block Olds heads.

If by "5" intake you mean the aluminum A5 intake, that's not even good as a doorstop. It's designed only to match the tiny ports on the 7A heads. If you really have the 1972 7A heads, definitely get rid of it and use a Performer or Performer RPM.

Thanks for quick answer! Heads are 7a, 70's. Intake 5A (edit, it was 16), "OLDSMOBILE" text on top. Can i straight bolt on performer ? How about cam?

Karpov

i remembered totally wrong. 16 intake with olds text. Thats my intake. Now whats the power?

cutlassefi

Performer or Performer RPM will bolt right on if you have 7a's.

What's the gear, tranny, stock converter? What are your intentions? Gotta know that before we recommend a cam.

Karpov

3.08, th200r4. I cant change cam, i just wanna know is my cam piece of... That engine is just rebuilted

cutlassefi

For your combination that cam on a tighter lobe sep would have been better but it doesn't really matter now.

Karpov

okay! How about 16 intake? Is it good or not?

71 Cutlass

Torque number is probably wrong. I've had my 71 350 (has # 7 heads) on the dyno once, after installing the Edelbrock (Phoney) Power Package. Highest TQ #s at the rear wheel was 260.

Karpov

How about hp on your engine?

71 Cutlass

At the rear wheels...sad...218.

Karpov

Ouch! Is that same power package serie who promises 1500$ +400hv in many engine but without edel heads? what is your guess hp and tq on crankshaft etc?

71 Cutlass

It was the 397 HP Power Package from many years ago. As far as guessing HP & TQ, add the usual losses of 15-20 percent.

Karpov

how about the 16 intake? Do i keep it or buy edelbrock?

Aceshigh

Are you serious ??
I wonder what the hell is in my 1970 350's rebuild then.
I dyno'd out at ~240hp/325ft lbs @ the wheels.

Only thing I know is I have an RPM intake, #6 heads,
updated valvetrain, and a 750cfm edelbrock that's
dumping too much fuel in. But no idea what cam.

You have to remember not all dynos are created equal.

"You have to remember not all dynos are created equal." x2...

There is a great article on this in last months Hot Rod magazine!

I am not familiar with the 16 intake. Is it an Olds factory production piece? Is it cast Iron, or Aluminum?

From your references to hv and nm, I am guessing you are not in the states, correct? Where in the world are you?

Karpov

Heh. My scrappy language reweals me better than units that i use Am i right? Im from finland. Gasoline pays allmost 2$ liter, heh. 16 intake was 74-77 4V i think, alu maybe? There is egr.

71supreme

hehe, your lanquage is fine, and better than many Americans! I will be so glad when gas settles down! Ugh!

If your intake is aluminum, keep it. There aren't many options for Olds 350 intakes, and the biggest advantage seems to be the weight savings versus cast iron.

Opinions on the EGR vary, and i don't know much about them. my 71 doesn't have egr. If the car it's going in is a 71, you can block that space with a simple plate. Many places sell them.

Karpov

Egr is plated! How much gallon pays now in states?

71supreme

"Egr is plated!" - excellent

Fueling up here in Maine is between 3.25 and 3.75 per gallon (close to $1 per litre) Doestnt sound too bad to you I'm sure, but we are used to something closer to $2.50 per gallon, and it seems headed to $4.00 if things don't settle down in the mid-east.
