Engine build question

[bryankichler]

I am currently working on plans to rebuild my engine. I am a deployed soldier and noticed right before i left my current engine had metal shavings in the oil so im going through it.

I am going for a cam change mainly current cam is unknown I have no means of checking prior owner said 292 duration pretty vague. I also had a problem with it running lean so carb choice would help. So to shorten this up below is what I currently have and current plans for the engine looking for criticism and Ideas.

Currently have
Engine: GM 355
Heads: 487x slight porting 2.02 int / 1.6 exh (1.6 roller rockers)
Compression: 10:1
Intake: Edelbrock EPS
Carb: Edelbrock 600cfm
Ignition: MSD HEI Distributor w/ stock coil

Projected Plan
Engine: The plan is to freshen up the bottom end bearings rings arp bolts throughout
Intake: Edelbrock Performer RPM Air-Gap
Carb: Holley 750 DP (open to suggestions)
Cam: Comp Cams Magnum 280 Hydraulic Roller (Adv Dur 280/280, Dur @ .50 224/224, lift .525/.525, lobe separation 110) (Open to suggestions)
Ignition: MSD HEI Distributor w/ Accell super coil and MSD 6AL

To help in giving advice below is the rest

Transmission: 700R4 from Pro-Built Automatics Street/Strip
Converter: Stall will be determined on cam requirements
Rear End: GM 12 Bolt w/ Eaton Posi 4.10 Gears and 28" tires

Driving Conditions: Street/Strip. It will see short trips cruise's, 3 blocks to work and back. The occasional long trip (driven to track, reason for overdrive cut down RPM's on the highway)

I am sure some of you guys can really pick this apart. While deployed I have the time to take advice and do this right. I am not looking for anything extremely radical just something to match up with what I already have. HP/TQ figures would be killer to.
