all you need is a 70's old's cutlass, a 455 *** torker intake. 850 carb., turbo 400/b&m shift kit. 10.5 slicks 30" tall, 4.88 12bolt posi, a long duration cam, and good weather. With a 3500 stall converter, you can get really fun wheelies by flashing the converter. Neat plus. You should top out at 110- 113 mph @ 6000 rpm.

Well, lessee - I think you are in the right direction, but spinning a 455 at six grand is probably not a good idea.  Oil drainback problems and starving the rear con rod bearings are a couple of things that come to mind.  Unless you have studs and at least straps in the bottom end, main cap movment is likely also.

Now, I agree with your overall analysis.  Anything pre-73 is going to be the old body style and should be around 3700 lbs soaking wet.  That's what my sons 72 comes out to, and it's a small block.  Add 150 lbs for the big block because differences between the engines aren't that great weight wise. 

The 455 is a torque monger that will throw down in the lower part of the RPM range.  Hit the gas and it's producing torque faster than many other V-8s.  Cam selection would be based on an RPM range of 2500 to 5500 RPMs.   You go any fast than that you will float the valves, unless you are using roller rockers and a roller cam - oversized springs.

Agreed that a 12 bolt is a good idea if not a necessity.  However, with a 3 speed transmission (turbo 400), 4.88 gears are going to be way too steep.  You would have trouble putting the torque to the pavement without big time rear suspension modifications.  Also, before you could get to 110 mph the engine would be wound pretty tight.  Change the gear idea to something tamer (373s maybe?).  The other thing that could help in this buildup would be a properly decked out 2004R modified to take the punishment the 455 would dish out.  They are out there and are a race standard - my friend races them in his Pontiacs and I can't tell you how much his engines are putting out.  They are impressive.

Your induction selection I wouldn't argue with.  In fact I have the same set up new in my basement just waiting for an engine.

This was the car that my son and I were working on before he took an interest in another vehicle.  It's all down there waiting to be put together, but I refuse to do it alone.  If that happens either it will go to the highest bidder, or I will buy his portion out and do it myself.  He actually wants to drive a foreign car - BWAAAAAAAA he ain't my kid.  He was raised better than that.

You don't need all of that to make a 455 Olds run 11's. I am using a Performer intake, Q-jet, stock size cam (274/280 seat-to-seat, 15" of vacuum), stock compression (9.5:1), stock head flow, stock crank and rods, 1.75 headers, 2.5 exhaust, 2500 stall, 3.73 gears, shift at 5000rpm, 275/60/15 M.T. drag radials. 11.85 @ 112mph on 87 octane in a 3600+ lbs car. BTW, you won't go any faster with the performer intake if you use a stock non-EGR intake. I use it for weight savings. 44lbs lighter than stock. When I had 2.73 gears it ran 12.60's with a slipping trans. The tranny poop the bed after that run. That's when I put the 3.73's in and a new tranny and it ran 12.09 first time out. I have done some tuning on it since then and have run 11.85. Very streetable car.  

You guys realize this makes me very excited about the 425 Olds I'm going to pick up this weekend right?  Granted mine will be dead stock for awhile...

Still...this is my first big block...and I'm very excited.

Starting in 1967 and running through 1974, Baldwin-Motion offered SS (425-hp) and Phase III (500-hp and up) big-block Camaros, Novas, Chevelles, Corvettes and Biscayne Street Racer Specials. Cars were sold at Baldwin Chevrolet or Motion Performance, converted by Motion and financed and delivered by Baldwin. Phase III 427 and 454 cars came with a written, money back, quarter-mile performance guaranty from Joel Rosen.
 
All Baldwin-Motion sales promotion materials carried Rosen's guaranty. “We think so much of our Phase III Supercars that we guaranty they will turn at least 120 mph in 11.50 seconds or better with an M/P-approved driver on an AHRA or NHRA-sanctioned drag strip. Phase III Supercars are completely streetable, reliable machines that will run these times off the street.” There never was a single comeback!

I love these cars ever since I saw a orange and white 70 Camaro SS Phase III in Omaha as a kid. Side pipes, loud paint, louder engine way cool. I've even seen one of their LT1 power Stinger Vegas. I have never heard of them making a Biscayne. I'd kill to see one of those. I've been considering painting my 65 SS like Baldwin/Motion style. If you have a link or a site I could look at that would so cool.
