What makes you say the cam is too small?

...Past experience. You have a too long a stroke and too many cubes for 248@50. Call Mile LeFever. Call Dave Dralle. Call Keith Kraft. Call Comp Cams

I checked a build sheet on Gessford Machine Website for a 427 Shelby block. Cam was 33-245-4 using 4.27 pistons.

....And, your point is?

By no means do I claim to be a mechanic, so don't take this poorly.

....I'lll be fine

What do you or anyone else suggest I do or ask of my mechaninc to try and hit the 500HP mark w/o spending too much more money (if anything at all)?

..I would find out the flow numbers on the heads in order to see what they want in a cam along with how you are going to use the car. Some people don't like a really radical idle at over 1000 rpm's. I don't mind it.

You still didn't tell me the torque. I would have thought you would have had that number with the hp. The rest you can ask Joe.
Don't get me wrong, Joe is a good builder and been in it forever but, since engine building is not an exact science, maybe this was just not a front runner for one reason or another. With 427's, the power is made in the heads and cam along with other variables. It's obvious that the cubes and stroke didn't do the trick in this case. Now, you just have to figure out why. I would compare it to a Keith Craft build. He does make a lot of power.

I will ask the questions you mentioned below.
