Depending on what pistons you go with you can build a 355 for around $1000. That's just for the pistons, rings, bearings and machine work to the block.
On the same token you could build a budget 383 (cast crank, stock rods and TRW forged pistons) for about $1500.
I built a 355 for my Z with TRW forged pistons. The compression with the heads at 51cc and the block at a 0 deck is about 12.34 to 1. With the CC306 cam I am looking for it to his about 420rwhp (which on a good day should net a low 11). If I put a 150 shot on that I could easily run mid-low 10's. The car has awsome driveability also.

So once you factor all that into the cost of the motor you will still have about $3500 or so (with a GOOD set of heads).
I got a great deal on my heads. How well the heads perform on the motor in comparison to what they flowed (which was bad ***) is what's going to make or break how much power I make and how fast the car is. Heads are where the power is, strokers make the torque. For example, if I were to do a 383 instead of a 355 with everything else exactly the same I would prolly have about another 10-15 rwhp, but 30-35 more rwtq.

can u still use stock casting heads my chambers are probably a lil less than stock cc since I had em decked when I blew a head gasket but I ported and polished myself so id like to keep the heads since my numbers were better than even people with my cam and lloyd elliots. I was trapping 115mph when most were in the 111-113 rangeand they had sixspeeds with the same mods as me and also I later may go to a bigger cam but for right now I have a new chain(may go to double roller or lt4 extreme) new lifters are on the way. Here this may help.....last winter I did heads/cam :jet hot lts: hardened push rods: 1.6 rrs: new valve springs: portmatched intake: and u know just some cleanup stuff but never touched bottom end

I haven't run low 11's YET. But that is what I am hoping it will run. I only have about 1200 miles on the motor. 2 guys I know with similar setups (stock bottom end with the same cam I have and similar heads) ran DEEP in the 11's. The flow numbers on my heads were right there with there's so I am optomistic. After I get the car dynoed and make a few passes I think I am going to change the cam out (depending on the rwhp and et). I can make more power with the custom grind I have picked out, it's just how much and is it worth it for the extra power.
We'll see!!!

.Any ways just a though for you. Some guys prefer to start with heads and a cam. Add a shot of juice and they are happy with it, but I am sure if you are going to be running the motor hard with the 20lb of boost you were mentioning I would not run anything other than a forged motor. Otherwise

If your wish is for a potent (400+rwhp), very streetable 355 with a hydraulic cam, then you should talk to Phil at www.advancedinduction.com
He has done the head and cam work on several of my friends cars (daily drivers), and they all have made over 400rwhp either on a stock shortblock or basic 355.

If your staying naturally aspirated and/or staying below 550 HP at the crank, you'll be safe with the stock LT1 powdered metal rods. Lots of guys have ran that much on the stockers. Just add ARP rod bolts, have them resized during the rebuild. I had my 355 shortblock put together by IRS (internet racer supply) back around Jan 2000. I've raced it monthly ever since then both on the track and elsewhere( <-- if you are a police officer, I'm lying ) and it's done great. Best so far with the old cam/home ported heads was 12.0 @ 111 mph. Adding a 100 shot of n2o brought the best to 11.1 @ 121mph. I now have new bigger cam and pro-ported heads. No times with the new stuff yet. If you have the extra cash, go for the 383. If not, I think you'll be VERY happy with the 355 anyway.
