This next one...

Torque falling off: Can be a number of things, typically a short stroke big bore doesn't do it as bad as a long stroke and smaller bore. This is why we have spread bore engines to allow larger bores...

Opinions are gonna vary on this, but the major factor IMO is this:

It's not really about the brand (ford, chevy, mopar, and etc) but the research put into one basic combo for a dirt late model....

Lash: I would talk to the cam manufacturer, depending on the curve of the ramp during opening and closing so you have an idea how far is safe to go. This is mostly on loosing it to make the cam...

Maybe this might make things clearer on the torque/HP/RPM:

Lets say you want 800HP at 8000 RPM, regardless of what the engine makes for peak torque or how the torque curve is shaped on the graph...

The item I mentioned as not being overly viable is the carb change, least as how you have described.

1. Obviously it's expensive to buy several carbs or just another one to try it.
2. Using a...

## deleted picture as it's too big and messes up thread##

Here is prime example: blue cam has more torque in the lower RPM ranges but drops off sharper at the higher RPM, thus it doesn't create a...
