I do respect a lot of the guys on here, but as an engineer I also have a great respect for data and facts. Most of the people on here who are the "expierenced" ones haven't commented in part I think because this such a well rounded package. Idealy I would step up to 4.56 gears, but 4.10's will work, and they were cheap. It won't have the best gas milage but for a weekend toy its a damn hard budget combo to beat. Sure its a solid cam and will need more work than a hyd. and sure it'll have a little rough idle but as an updated version of the 375hp 350 It's going to be sweet.
I'm going to guess 460/420 for hp/tq. That could vary some with my carb choice, and it'll be on roller rockers which I don't think I included before... Actuall street tune will probably be 430/400. That's flywheel too, at the wheels I'd probably say 380.
