how about this kit?

What do you think of this kit:
https://secure.pawengineparts.com/412_4Chevy.html

It's an unassembled 4 bolt 400 block .060 over unassembled short block kit.   Only thing I'm leary of is the .060 over bore.  Do you think this is too much?


SHORT BLOCK KIT Includes: for $1435.50

This would beat the pants off a GM 350 short block for around the same price.

Personally, I'd pass. IMHO, that .060 overbore is too much. Next rebuild, you'll have to sleeve the cylinders. I'd look through the local Craigslist/Junkyards/etc. and find a builder 400 and build it yourself. Or, you could build a 383 out of your 350. Budget priced 383 rotating assemblies can be had for ~$700. I have both and the 383 is heads and shoulders above a 350.

I found what I think is a cool 406 build...huge torque and good low end...perfect for a truck.  Basic ingredients:

400 bored .030 over
vortec heads
edelbrock performer RPM air gap intake
comp cams 280H cam
deep dish pistons to keep compression reasonable
makes 471 ft-lb all the way down at 2300 RPM...peak of 525 ft-lb at 3500 RPM and peak hp of 428 at 5500.  I was impressed.

^^ good reading.

Well, what do yall think of this one?  it's a (330hp / 385ft.lbs.)  350ci  turnkey.  everything, from air cleaner to pan to starter to serpintine setup to ac compressor.  I found it for around $4700 or less at the chevy dealer.

I figure with this setup, The final total would be around $5,300 complete.  That's for taxes and all the little things a new engine requires, mounts, hoses, oil, cleaners, etc.

Here's a very nice crate for the money.

that'd be awesome!  it would also cost about the same overall as the 350 I put above^^ 

I looked throught their store and found this one, same price but 40hp and 5ft.lbs more.

That one would end up about the same price, all finished, even with the gm serpintine setup.

I'd be kind of an idiot not to get one of these if they are as good as they sound.  It runs on premium gas, but that's fine, my old mustang only took premium and I drove it around for years daily.

Here's one from the same place that's even better.  It would be fairly unique for a while.  408 stroker from a 350 block.  4.03x4.00 bore/stroke.  500+ft.lbs. would move the old truck around nicely.

That's almost identical to my 383 spec wise. This one has a little bigger cam, though. I believe you'd be *very* happy with that motor.
