You know that they have to turn the mains down to 350 diameter, right? This can cost 150-200 depending on where you are. Most shops around here stopped doing it (it is a PIA) since aftermarket cranks are so readily available and affordable.

What about rods? Use the 5.7 350 rods if you have them. Buy pistons to match. It won't take much for that truck to 'scoot,' use the 882 heads to keep compression (and therefor temp) down. Just take them to your machine shop and have them done. Nothing fancy needed, maybe pin the studs if you can't afford screw-in and guide plates.I have heard that S10 cooling is an issue, but no personal experience.

Cam depends on how streetable you want. I like old corvette grinds, like the 327/350HP grind, or if you want bigger, summits .488 lift 234 adv duration is a nice one.

Of course you need a 400 balancer and flywheel

5.7 rods? Howcome?

Most I hear is to use the 6.0 rods if you need new rods and pistons.

In theory, there's no difference between theory and practice. In practice, there is.

I usually use 6" rods, but he said he is on a tight budget, so I thought he might have the rods out of the 350 already. If he has to buy rods, yes I would go 6", although pistons are a few dollars more, and the sides of the rods should be clearanced for cam lobe clearance. Actually, I do that on 5.7 rods also to be safe. A couple cam lobes are within a hair of the rod or even touching slightly.

That is a weak rear end - isnt it the same as in the 3rd & 4th gen camaros (7.5")? If it were me building on a budget, I wouldnt worry about that till it snaps, just to save extra $$$ for the engine. A posi rear will probably be mandatory (hey smokey!) unless you plan on doing the one wheel peel!

Be sure you get the lower end balanced. The amount of material taken off my stocker 5.7 rods was unbelievable. Its a big chunk of change, but worth it if you want it to live long. I paid $250 to get mine spin balanced and never regretted it. Remember its a lot easier to swap heads than low-end parts, so I would not scrimp on the lower end if money is a question.

A good rear end swap is a 2nd gen F body 8.5" 10 bolt. They're only a slight bit wider than 3rd gen rears and will hold up to way more power than any 7.5". It'll cost about 300$ for the rearend plus welding work without new gearing. You'll need some spacers though, around 2" per side. Long wheel studs are required. Its well worth it, I've seen ppl with power in the 500+ range without any problems on stock units. Of course, a 9", 12 bolt or Dana 60 would be a better swap, but these 8.5's are easy to find at most local boneyards, and the posi units have an Eaton posi which is rather stout. Just a thought.
