For pistons I would go with a flat top with the valve reliefs also in interest of cost.
For bearings, assuming your crank is good you would probably be able to go .010" under on rods and mains with no issues and parts are again readily available.
For the cam I would stick with something that is fairly mild and the Isky cam you mentioned would probably do well... I think that you will find most of the money is tied up in the heads and machine shop labor.
Northern auto parts does offer a nice rebuild kit with nearly all the parts you would need at a good cost. There is no need for expensive forged pistons for what you're trying to accomplish.

Thanks, also I said hypereutectic, not forged lol.

Thanks for the link, but I dont see any brands there, I'd rather know who/what I am buying.

I likewise don't think the computer is going to like a cam with more than 195- 205° duration at 0.050" (closer to stock) .
Your going to have to have a custom chip burned for the OBDI computer and even blanks are getting hard to find from what my computer guy keeps telling me (but could be a stall because this guy is frickin Sloooowwww,, 18 months and 3 chips to get this TBI 383 of mine fine tuned)
Myself,, if you are strictly MPG oriented, you better stick to the stock setup and keep with the thought of putting new surfaces where needs to be new surfaces and not change the configuration / calibration.
That statement is somewhat of a oxymoron. Horsepower is nothing but an equation of torque and time. (time being derived from the RPM's)
Formula is: (torque*rpm)/5252 = HP
i.e.
300 pounds of torque at 1000rpm is 57 horsepower.
300 pounds of torque at 5000rpm is 285 horsepower.
TORQUE is the power that twists on the driveshaft and make the hulks move and accelerate. Making torque in your USABLE rpm range is all you need to be interested in. With the swirlport heads your foolish to even think about any rpm over 3800-4000. So you want to build and cam your motor concentrating on idle to 3800. This is going to be a SHORT duration cam (like stock). Sometimes it's hard to improve on the R&D done in Detroit 
Fust a FYI, I believe the 88-94 350 made 190 HP,, it was all about torque from idle to the mid 3000rpm range. |
I am swapping the heads to 96-00 Vortec heads, I did forget to mention that the comp would need to be programmed. How much does it cost to get a it reprogrammed?
My inspiration is this:

Also, if this helps, the specs of my TBI 350 are:
L05-350-5.7L | 210hp | 8.3:1 C/R | Cam 0.50 : 194/202 - .385"/.403" : LSA 112 | 55lb/hr injectors
