For a 350, its about 3k......rebuild with forged pistons, AFR heads, hyd. roller cam, Edelbrock Ari Gap intake, and 750 cfm carb. Then, a 3k stall would finish it off with 3.73s or 4.10s.
For a 383, about a 1k more due to extra machining and the rotating assembly.

I got a 383 for my 1984 K-10 from here. http://www.sehrpower.com/
Its fully balanced and I opted for the Sportsman II heads.

If he has lots of money to spend he could get a small block 427. I always wanted to build one of those. Incase you are wondering, Yes I do mean small block. World products makes the block.

Hydramatic

383, dual quads, longtubes, WILD cam, 4.11 gears, lightweight driveshaft, weight reduction, and a badass stall.....

Oh yeah, weld the front bumper of a 4th-gen Firebird on there for some aero! lol

I'm enjoying this thread... my truck is all original... 305, 350 trans, 2.73 gears.... so I'm taking notes.

406ci, 383ci, or 355ci, 0 deck the block, good flat tops, Nice rods, good crank, Trick Flow heads, Victor jr., 800ish cfm carb, 240ish/250ish solid roller with about .630 lift on about a 108LSA.

TH350 built good, 3500-4000 stall (more like 4000), 4.10's or 4.30's.

Highly variable depending on the specific parts he uses. I say if he isn't going to go nuts with nitrous go for a SCAT cast crank, SCAT I-beam rods and Keith Black hyperutectic pistons for the rotating assembly. Canfield/Trickflow heads are a good $200 cheaper than AFRs, so thats something to think about. A flat tappet cam would make less power but would be a ton cheaper than a roller valvetrain. Etc. etc.........

NO kidding, I am definantly taking notes! all I have is MSD ignition, flowmasters and a transmission kit

I got smoked the other day by some guy in a Mustang, it sucked...
We were already going 70 so its not like I had much more, it would have been better from 0 to 100+

but yeah good information

There is some good info and some bad info in this thread. He will not need a BBC or any type of boost or nitrous. Go with a 383. Do not buy hyper. pistons. Best bang for the buck would be a set of forged TRWs. Shoot for around a 11:1 cr. A SCAT cast steel crank ($269~) is a good part. It's what I'm running for now as a matter of fact. Next, I would look at the vortec top-end kits from SDPC.com. Go with a 1-inch carb spacer and an 850 dp holley. Atleast a good HEI distributor, I run all MSD parts. Then a set of cheap 1 5/8 headers will do just fine.

For the tranny get a 3000-4000 verter, get the th350 rebuilt that is already in it, and you will need a tranny cooler! Out back that 10-bolt will last for now. So I'd just install a full spool (does fine on the street) with a set of 4.10s and a 28" tall ET street.

You'll be at 12.80s trapping about 103-106. Good luck!

Good info, but I disagree about the pistons. Myself and a few people I know have had great success with KB hyperutectic pistons. Mine were in an NA engine, but friends have run them in 525hp NA engines and nitrous engines with up to a 150 shot. I don't know about any other hypers, but KBs kick *** and I would buy them over TRWs any day of the week. If you are going forged my opinion is to spend a little more and get SRP, JE, Wiseco, etc... Check out the LT1 guys over on camaroz28.com running KBs in 500+HP 383s.

Vortec heads are certainly something to consider. I haven't been too interested in them since aluminum heads are pretty reasonable. I didn't even think of the ignition but an HEI is definitely the way to go and you can't go wrong with MSD.

Anywho, lots of information here for Dry_Kill's friend to consider.
