So with my parts, I should pretty easily be able to keep up with my dad's 400 and his turbo 400 tranny? His stock is rated at 340hp and 440ft/lbs. But stock is also 10.25:1 comp. ratio and he's lowering that some, but he also got the heads ported and polished, headers, and a large cam. Other than that, it's pretty much stock internally. I should be getting to see it on the dyno next week so I can probably give myself a good guess how tuff building the 250 to keep up with him is going to be.
