roller cam setup ?

I'm getting ready to build a 393 for my truck. I want to use A roller cam in this one so I have a few questions for the pro's in here. I think I want to order the comp retro kit, here's where the first question comes in. If I use this kit can I get factory roller lifters to use with an E-303 cam. Now for the next question, can I get a set of pushrods for a later 351w that came factory with the roller cam.

here's what I have planned so far.
block bored .030 over
3.85 stroke crank
stock 351w rods
hyper 302 pistons
P and P E7TE heads with 1.94I and 1.6E
stealth dual plane intake (considering single plane)
750 holley double pumper
E-303 roller cam (I think,not sure on that yet,but definetly a roller)
headers with dual 3" exhaust
comp. ratio will be close to 10

I'm shootin for 400 HP and atleast that much torque.

thanks in advance,
scott

First thing, If your 351w was not a roller block, you need the retro kit.

2. You will need a retro cam. They are ground on a small circle.

3. A Motorsports cam will not work. large circle grind.

4 Stock roller lifters will work and you need pushrods that are 7.70" long

The lifter bores are taller on a roller block. If you don't get a retro cam the lifters come out of the block too far, and oil leaks into the lifter valley.
A Comp Cams retro cam #35-442-8 is like an x-303
