460 build

i want 375-400hp out of my 460 while still being able to run pump gas. would this be feasable if i ran some SCJ heads, a cam, a pre-71 timing kit, a high-rise intake, some long tube hedders and holley 750? i need to be able to run pump gas because this will be my daily driver/show truck.

So this kit claims you must have a 2600-2800 stall. What's the stall rating on a factory C6? Or for that matter, a E4OD?

I'm debating right now to do a Holley EFI kit, or a stand alone EFI kit from 460efiguys.com. (Pretty sure i've talked with you about this before). I'm leaning a little more towards the Holley kit, now that i've realized that it appears to be a lot easier, and with this kit, i'd be able to utilize all the power she's got!!!

I know the stock converter does not stall that high. That is probably why they raised a red flag on that. That brings up a important point, you can't stick a fire breather engine in a otherwise basically stock truck and expect it to work correctly. Most higher horsepower engines create this horsepower at higher rpms. So a large heavy 4x4 truck with oversized tires is going to require some modification to make it all work out, like a higher stall converter and a re-gear in the differentials.
