Eddy 800 AVS CH4B (to fit under the Air Grabber) 30 over 440, 10:1 Stealth heads Comp Cam 21-223-4 .477 268 Dur TTi 1 7/8 into 2.5" stock torque converter 3:55
It goes good, lots of torque, but doesn't set the world on fire with approximately 450hp. It spins the wheels easy so I don't think a high stall converter will make it pull harder...unless I'm mistaken.
I'm limited to the intake manifold due to height restriction with the Air Grabber (gotta keep the motor stock looking)
So, how much more power could I get with a hotter cam? More than 50hp? If not I'm not going to bother.
Thanks

OT I'd suggest dialing in the A/F ratio and dist subsystems

Porky has a right to his opinion, but....... The only people that think like him are those that run mild cams and never exceed 4500 rpms. Thats fine for them.
Please, tell me how fast your street car is, how big your cam is, and what RPM you shift and turn throgh the traps.
I suspect you have no idea what I think or how I build my car.

A 50 horsepower gain would take some better intake setup and at least 245 degrees of duration, I.E. a big jump in cam size and 10-12 inches of idle vacuum. CNC ported heads will probably net you half of that if you prefer to not give up any street manners. I would agree that I don't think you will find 50 usable horsepower out of any cam without other changes.
Do you want more horsepower or do you want the car to go faster? As the others said there is probably alot in your tune up.
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

A good torque convertor will help way more and not be a PITA.

Agreed...people always seem to overlook the converter. Good ones aren't cheap, but they are worth it in an automatic car.

The machine shop that built the motor said they designed it to be 1hp/ci and be a great torquey street motor to work with my set up (stock vert, 3.55s) I believe they achieved that.
However, I wanted something more radical and said how about a stroker? They said you don't need that, don't want to do that to your numbers motor and you should be happy with a torquey 440.
I should be happy but I'd like another 100hp plus at least the torque I already have. It sounds like I'd have to go to heroic efforts to do that though (512ci, convert and 3.91's). I want it to pull HARD. Right now it just pulls quite good.
The idea of the six pack has been on my mind. That, a cam, vert and 3.91s should make the car snapier

I'm running a Turbo action 3800 and 3.91's w/ my six pack. Swaping converters, gears and intake/carbs isn't an easy or quick task. Not to mention cost. I have less motor and I can tell you this car is not a ton of fun on the street. Runs and drives nice but it explodes the tires (even the ET Pros) without much effort.
