What do you guys think?

Ok, after getting a deal on some heads and people giving me some advice on some other things, I changed a few things about the build. Now that everything is ordered, here is the final setup on the engine. The tranny and rear end havent changed.

Engine:
318 bored .30 over
360 crank turned down
It comes out to 348ci
10:1 compression
302 heads
Edelbrock performer intake
Holley 650 DP
1 inch phenolic carb spacer
Summit Fuel pump
Summit double roller timing set
Comp Cams 270/270 duration .470/.470 lift
Comp cams Valve springs
Comp Cams Push rods
Melling Std vol. oil pump
Stock water pump
Hooker Headers
MSD Pro Billet distributor, coil and 6AL ignition box

Also, the tires will be 26x10.5-15 M/T ET Streets

These changes should get me pretty cose to the 400hp mark im hoping for.
