Build me a 350 Chevy

OK guys, I would like to toss around the idea of putting a 350 Chevy in my truck, a 68 GMC 3/4ton 4x4. It has a granny 4-speed and 4.10 gears, along with 33" tires. I would like to have a 383, but I don't have enough money to build a decent one. This is what I would like to have:

-good reliability
-a SBC with good low-mid range torque.
-good pick-up when you stomp on it.
-Ok gas mileage (11-14mpg would be good)

What would you guys reccomend I use for cam/intake/carb, and other parts? I'd probably use the Northern Auto Parts $170 350 Chevy kit. What would be te best bang-for-the-buck combo? Thanks for answering my questions, I appreciate it.
Jake

a Edelbrock performer package would suit you nicely, it includes a performer intake and camshaft. A Quadrajet carb or any vacuum secondary carb that flows around 650cfm. Tune it up with the best pieces you can buy with spiral core plug wires. A set of small tube headers with dual exhaust and a cross over pipe. I would just get the northern rering kit, the kit that comes with basic cast and hyper pistons have .020 whacked off the compression height. The comp height is suppose to be 1.560, but on the cheaper pistons that come in that kit are 1.540, which kills compression, quench, and power. You can go on ebay and get a set of 2 valve relief coated skirt flat top pistons with the correct compression height for around $170. This package will give you good mileage and good power.

I definately would,nt use a Victor single plane intake on a grunt motor, totally working the opposite way. If you are'nt going to do the rebuilding find a competant shop who can build a good long block with ARP rod, head and main bolts for insurance. Try to keep it at 9 to 1 compression, a cam with around 204/214 dur. an Edelbrock performer dual plane intake ( a VICTOR???) and one of the new Holley street avenger carbs. If you have a little money left over buy a set of Dougs TRI-Y headers, they're good for torque. Spend your hard earned dollars on good parts and not chrome or RACE CAR stuff.

I would get a set of Vortec heads,Performer intake,Performer 600cfm or Holley 650.9:1CR,If you have the money buy a set of roller rockers1.52 ratio(Not a neccisity but nice),and maybe a gear drive(Though a double roller would be fine and cheaper).An Good Hei(I get mines from skip white on ebay 65k hei).A set of headers from summit.I like Flowmaster mufflers but summit turbos are fine also.and cheaper.For Cam.I had a similiar 355.And I installed a 256H xtreme energy cam(12-234-2).Leaving the mustangs and honda,s behind me was no problem.I got 18mpg on the highway,I averaged 14 if I kept out of the secondaries.My truck was a 72'C10 with a th700r4 and tci breakaway stall.3.73 gears/powertrax diff.I changed to a 383 with a 268H xe cam because the 256h was'nt lumpy enough for me.It only sounded a little different than stock.

Thanks for the input guys. So a carb/cam/intake to make it more responsive, and if you have money left, some Vortec heads. If the rebuilder pistons have .020 off the compression height, couldn't you shave the heads to make up for the lost compression? How bad do the 882 casting Chevy heads flow? Thanks for the help.

I would port the heads if it were me, but I realize not everyone knows what they're doping with that. I would go with the VooDoo 256 cam, 1.6:1 ratio rockers, long tube headers, a performer intake. If you can polish the chambers and get 9.3:1 that would be about perfect for a truck. A good HEI is essentail.
