I have a 455 j block from a 73' Delta 88, Engine is going in a 72 Cutlass 2dr. Vehicle is used as a daily driver but would like it to be a head turner. Maybe a 292 or a 312 cam if possible. I love the sound and power display. Not really worried about gas. I would need a recipe including intake manifold, carb and most other parts excluding pullys and brackets, lol. I have a TH400 tranny freshly rebuilt with a 2000-2500 stall converter. Also we would like to put a functioning W-30 hood and air intake sytem.
I have the upmost respect for Oldsmobile, it has its own beautiful style.
Thanx for you time.  

I have not been around for awhile but can give you some advice on your J block. As you state, it is a newer block and probably has smog heads. The 455 is good to work with because you can still find Olds stuff at good prices, and keep your budget in line. First, find some C or B heads and have them redone. C heads are best, but either will boost compression and give better performance. The Edelbrock heads are good if you can afford them, but C heads have similar flow characteristics.  Cam choices, well they run the gambit from mild to wild, but I suggest making a choice that will give good power along with good road manners. I have a small block with milled big block heads on it, and a real steep cam. While it's fun to drive on a dry day, you can get sideways in it real quick.  I have a Mondello catalog someplace and can give you some options if you want.  They seem to have cams for just about any application that you could possibly want. There are good intake and carburetion options out there. I bought an Edelbrock Torker (if memory serves) for my 442, but kind of wish I bought more of a standard type. I am going to have to get the exhaust ports plugged on the heads as there is no cross over on the intake. That's ok, but just another step.
If you are going to build the block, you may want to research some oil flow restricters (I have never used them), but there is a good arguement for them. IE if you use a high volume oil pump it tends to pump all the oil up top of the engine which can cause trouble. They are sold by Miller Racing or Mondello in kits.
Always go to a double roller set up on your timing chain, even if you leave the rest of the block standard. They came from the factory with nylon gears that puke at the 90,000 mile mark.
If you are getting the block machined anyway, good upgrades are main studs, and getting the rotating assembly balanced.
That should get you started.  Let us know how it goes.
