im wondering if the x303 cam would be a good cam to run in my notch,a couple of people recomended it,but im open to any other sugestions,mods so far are,
stock88gt short block
289 heads ported and polishe w/194-160 valves
torker intake
mallory 6al ign
long tube headers
1.6 roller rockers
600cfm holley sonn to be a new 670 cfm street avenger.

john stock50lx who i bought the heads from says the springs are good for aroun 550in lift

I would go with a Comp Cams Extreme Energy series cam. They are dual pattern and have a lot newer lobe design.
With a Comp Cam it will idle way smoother.

I would suggest Anderson Ford Motorsports cams. I have one that works really well for me and does exactly what it was advertised to do!

If you're serious about it, I would go to FTI or a similar outfit and get a custom grind. Shelf cams can be good if you know what to pick (this is what you're really paying for in a custom cam), but alphabet cams are very old. There are many better designs available.

The process of picking a cam is not the hard.
Comp makes it very easy.
TECHNICAL ASSISTANCE:
Phone: 1-800-999-0853
CAM HELP
Certain people who offer custom cams are just using this same process.
They sell you a off the shelf Comp Cam with the sticker taken off as there own custom grind. Marketing is a wonderful thing. Every one I know that has used this process has been very happy with the results.
We've used Anderson cams with mixed results. The newer Anderson cams are better than the older ones. I would say their cams are more for Drag race use.

I'll go a step further and say pick-out your Comp Cam specs and have Delta Cams gind one for you at a fraction of the cost. I think the Ford Alphabet cams are designed for EFI and RedRum is running a carb.

My X cam runs good but the design is probably 15 years old, I think something newer would give better results.

The B- cam I believe is the only one for the carb motors.

Whoever you decide to go with -- you will get some different opinions.

Pick a company you like, talk to them and get their opinion, and be happy with it.

I wouldn't run an X cam in your motor. although your motor breathes easier than a lot, you should find a cam that makes power where your motor does. Max lift I'd recommend for your motor would be about .525-ish and duration should be like 218/212 @ .050 or less. Don't over-Cam your motor, it'll just end up being a dog under 3k, like mine 14's at 103 trap.. *sigh wants a smaller cam.

If your running stock pistons then there probably isnt enough piston to valve clearance with a .542 lift X cam.

Just Call Delta and talk to Jerry. Tell him what you have in the car and what you want out of it. He will hook you up, usually next day and at a great price..
