ZZZZZZ,

This is Randy Ritchey again, you listed good parts, sounds like you are on the road to getting a nice 428. However, it is hard to "guess" what your dyno results will be because you can give the same parts to 3 different builders and get 3 very different results. It all depends on how your parts are prepped and assembled. If you are using "out of the box" Edelbrock heads, you are not going to see 600HP. You won't get that high with the comp 292 either. Please don't mis-understand, if your combo is assembled well, you are going to be pleased. My guess is that you will have 420 to 450 HP and probably 500 to 530 torque. That's enough to make even a heavy car fun to drive. Please post your numbers when you get them so we can all know how it came out. Most of all - have FUN with it!

Have a bessed day!
Randy
