1/4 time, hp, and torque estimates?

as the title says, i was wondering what to expect as far 1/4 times, hp, and torque from my setup soon to be completed.

Engine- 350 block 2 bolt mains with .030 overbore, hypereutectic flattop pistons, crane cam with .467 lift on int/exh and 110 deg lobe separation, GM Vortec heads, power plus vortec intake manifold, edelbrock 600 carb, and a nice shiny air cleaner.

Exhaust- Hedman shorty headers, custom mandrel-bent 3" y-pipe, no cat, and flowmaster force II catback (30 series muffler).

ok, in addition to the stuff i copied from my readers ride page....this car is daily driven, and im trying to maintain tolerable gas mileage, so i dont want to go too overboard. i have a new distributor, wires, and spark plugs. it probably has around 10:1 compression. the ac, cruise control, and emissions equipment have all been removed. the transmission will be rebuilt with a shift kit and 2500 stall torque converter. the rear end will have a 3.73 rear gear ratio and positrac. im using regular street tires that were on the car when i bought it, and theyre in good condition. the suspension is all stock. thats all the details i can think of now. any suggestions for improvement are also welcome. thanks in advance for the replies.

It all depends on tuning but I would guess you should run a low 14 or high 13 sec 1/4 mile with street tires, traction will probably be your biggest problem. With some sticky tires you should be in the mid to low 13's. I would also think about moving up to a 650 holly carb if you want to improve your high rpm HP but its hard to beat the drivability of an edelbrock carb on a daily driver.
My guess on your power 350HP, 375ft/lbs torque

The 350HO crate engine is about the same as that with 9.1:1 and slightly less intake lift, and it makes 330 horsepower and 380 ft lbs.

after the street tires are worn out, ill probably get sticky tires. i was thinkin i would get a lca with relocation brackets, adjustable torque arm, and sfcs. would those be the best choices, or should i go with a different combo? the adjustable torque arm costs $355 at spohn, and im not willing to pay that much money....so would it really be necessary?
