I read the same thing in his post.You already have a decent intake and carb. I would focus on decent heads and cam kit. 450 hp is quite a a lot of $$$$$ and motor for a 350 and will probably not be very street freindly. If the car is primarily street shoot for torque. Best bang for the buck and a great set of heads for a novice Id pick up a set of Vortecs or a set of Dart iron heads. Determine what stall the tramsmission is, the gears in the rear and your rear tire diameter and call a handfull of your favorite cam companies for recomendations and then pick. Be sure to get new lifters and timing chain while your at it. If your 350 is not stock and build with forged pistons you can also entertain a small NO2 shot.
Your language indicates you quite new to all of this.....best thing you can do is read read read a lot and become educated before you go out and just buy parts than your buddy or the magazines say are best is my my valuable recomendation.

Maybe a crate would be his best option.
If he's really shooting for 425-450 hp.
Something that will live....
He would need better than stock rods I think to use a shim..hate to see the pistons kiss the valve's while having a little rod stretch.You can get it with a well designed system,
-350 Bored .030" over
-KB 105 Hyper pistons
-Dart 180cc Iron Eagle or a head of your choice around this size/performance with large chambers to lower compression a bit, with a .025" deck and an old steel shim it will put you right at 10.1:1
-Hyd roller 222/230 @.050 .509/.528 108° lobe center, Works very well with a mix of pump fuel and cam 2, if your looking for pump fuel only up the duration to 230/238 @.050 on a 108° lobe center
3.73 gears and your ready for some great street performance with a good dual plane Dart or Edelbrock air gap
No, he would need an Eagle or Scat rod. In a mild HP engine like that i would use Scat 4340 I Beam rodsHe would need better than stock rods I think to use a shim..hate to see the pistons kiss the valve's while having a little rod stretch.
But all of that could be ordered in a crate engine...Just plug it in and go...:thumbsup:
Your really not wrong at all. It's one thing to make HP, but it's a totally other thing to keep the engine from blowing it's self up. You had said you would like to make around 450hp. Thats more than 1hp per cube.so basiclly i would need couple thousand dollars to fix this engine up. i was hoping it just to be cam heads and rear. but the way it sounds. well i was wrong!
he could use stock rods, they may lasy 5 years, maybe 1, maybe 2 weeks. If i had to guess i would say you would be fine with stock ods up to 450hp with ARP bolts installed BUT by time you do that ou have $300 in the rods and you can buy a good set of Scat 4340 I beam or EagleYour really not wrong at all.

You are starting with a older used engine. 1st you must have a sound short block to start with. Maybe it's in real good shape. Can't tell till you pull it apart. If it's in good shape, you could make 350-375 hp and still be in a safe zone with the stock crank/rods/pistons.
And then just use one of the top end kits you spoke of.
the way you are talking, it sounds to me (correct me if i am wrong) that you havent done something like this before?so basiclly i would need couple thousand dollars to fix this engine up. i was hoping it just to be cam heads and rear. but the way it sounds. well i was wrong!
