It's All good Geno I have a 403 and just get too many of the standard"Toss the Olds and get a 400 Poncho"  answers!  If it were me and I had my way I would've put a 455 in Olds or Pontiac!  Ideally this is for my son and that's what the car came with so you work with what you've got!  On the other hand hindsight is 20/20 and I would have went another route?!  Like you said you learn from experience!  I have no emissions in the county I live so that's 1 good thing going for the Build!

I too have a 79 with the original 403 and would like to re-build the motor.  I live close to Huntsville Alabama and there is a suppose to be a good machine shop facility there.  I am not wanting to go for a high HP build and am looking at something below 300 HP.  I think that it originally was 185 HP and that would be fine also.  I am wanting to know how much should I be looking at for the rebuild?  I plan on removing the engine and disassembling it, so there will not be a cost for that, just the re-build.  I don't think I would need any high performance parts such  as a girdle, KB pistons, or anything past stock.

If you did any upgrades and kept it mostly stock IMO I would look for a aluminum manifold, "true" dual exhaust, a spicier cam, a true double roller chain,  and have the block decked and heads milled slightly for at least a little compression boost.  Put most your money in the heads as that is where you will see the most bang for your buck!  Again this is IMO!  And everyone has one... ;)

/nod to all of the above, this is what i have heard from many people....heads and intake are the most bang foor your buck plus headers if it doesnt already have them..

I would think a garage or engine remanufacturer would charge around $2-3k for a stock-style rebuild w/ regular cast pistons, resized stock rods, fresh bearings and rings, and a mild cam. That price would most likely be w/ the exchange of your original engine, or rebuilding yours if you wish to keep your original engine. A reasonably-priced upgrade is to replace the stock rod bolts w/ much stronger ARP bolts- I do this to any stock engine I overhaul and it's cheap insurance against rod failure. It's also a good idea to opt for your rotating assembly to be rebalanced- this helps your engine run smoother than a stock build and increases bearing life.

I know a local NAPA was going to do it for $1K with some flexibility on cam choice, but everything else stock...

Go with aluminum heads if you can get the block done for that price ha

that is free labor, do the math, cam and lifters $200 min, bearings $100 min, rings $100 min, oil pump $80 min, gasket kit $150 min that leaves $350 labor and we did not get to block cleaning, cam bearings, honing cylinders, better get it quick and get a warranty

No it actually is about 1/2 and1/2, Kit is about $500 and labor $500.   Break it down any way you want it is a good deal!  :D  Thing is I already had the head work done so just need the bottom half done now.  But I don't necessarily need new Pistons so maybe just a hone?   Sorry "Kid" Bad thread jacker! BAD!

Geno, I respect everything you have said so far and would like to keep in contact with you as I plan, acquire parts, and move forward with this build. I'm really lost at picking the right cam for what I'm trying to do. I want a hot cam, I'm looking for a rather hot build. Bulking up the block is of course going to happen. I wanted to run the 350 heads, or BBO heads just decked down for compression, but I'll keep an eye out for some 350 heads to use.

I planned on the Pypes true duels, and an performer RPM intake (its the go to and the shaker clears from my under standing)

I'm just lost on the cam. I want to utilize as much of the torque as I can with this, but want something up high too. Really just looking for a good, hot cam. I plan on going with a 1:6 roller setup too for some adjust-ability. Decking the block of course to up the CC's and for sure wanting to run the KB +6 dish pistons. I think this build is do able, I'm looking for a high TQ build...not HP numbers.

I'm going to yank the motor tomorrow, but only see one spot to hook my hoist to. What am I missing? Do you guys just hook it to the one loop and pull it straight up? Keep in mind the transmission is coming, while attached. Should I pickup a balance bar?
