455 in a 83 Hurst swap

[Intragration]

As far the swap the 403 is the same size ad the 307 but the 455 is taller. There will be more mods needed for the big block but it cam be done.

No mods beyond the basic Olds V8 mods were necessary to fit the 455 in my car. Even with an Edelbrock Performer it fits under the factory hood insulation using a 3" drop-base air cleaner. Notched valve covers might be convenient.

have a 1985 cutlass 442 all matching numbers. I recently rebuilt the motor and it cost me two arms an a two legs not just one.. anyway . I just put an olds 455 into my sons regal which came with a 307.. I tell you I should have save that money I used to rebuild the 307 on the 442 and just built the 455 and put it in there.. Bone stock olds 455 on his regal leaves a good 40- 50ft of rubbers on the streets and I believe I could get more if I keep my foot on the peddle.
In other words go for it its a very very easy swap one of the easiest swap I have done on a car.. as long as you lower the motor into the car without the exhaust manifolds and distrubutor.. very very easy swap. also You can still use the ac but will have to modify the bracket a little... Use all the 307 brackets and you are good to go... also the 200 willl not hold up .. you need the 400 th that came with that motor ..

One of the $1400 well built 200-4R's from the popular transmission builders will hold up just fine.

Where do you get a $1400 TH-2004r built to handle any kind of power?

In my experience you need to spend $2000+.

 

[olds307 and 403]

Extreme Overdrives, good for 450 hp, a well known builder.

Yes exactly no major mods needed I was just saying its a Lil more work compared to a sbo.

F3X Clone:

Bowtie Overdrives(and others) sells a 200-4R that will handle up to 500 hp and 450 tq for $1395. With that said, you do bring up a good point. If your hammering the hell out of it every day at the track with sticky tires you could break things. With moderate hammering on the street without sticky tires the above transmission will last for years.

I'm saying it's ZERO additional work compared to a SBO. If the car is prepped for an Oldsmobile V8, it doesn't matter if it's a 260 or a 455 when you drop it in.

I had Lonnie at extremeautomatics do two for me over the years, one as a rebuild for my GN the other for my 509 powered 442. Both worked flawlessly and held up. He lists $1,495 without any specials or price match but that includes him supplying a core which saves your core and one shipping charge and a converter so its basically just shipped to your door and comes with a warranty. He can also have the converter built up ie furnace brazed, anti balloning, higher stall etc for very reasonable. I used a 2,800 and a 3,000 stall lock up both of which cost me $300 at the time but that was with my converter. He has a machine to custom build his own valve body so it will shift properly at part throttle ie crisp but not a harsh bang and can provide custom WOT shift points to match your cam etc. You can get it done cheaper but you know what that usually costs you. Short of a bare bones old three speed for a drag only type car it beats all other choices hands down.

I'm just leery of these guys claiming to build a stout TH-2004R for less than $1500.

Vern, my brother and I called Lonnie years ago on your recommendation because of the low price. That must have been a friend price because he quoted us close to $2,000 for the same transmission. 🙁

That's when I said screw it and gave my brother my Art Carr TH-2004R and switched mine over to the manual.

Yike. Mine at that time was with me supplying a Grand National core & converter and he did say he gave me a good price as I was a customer referral but at the time I didn't know if he told everyone that or not. Was your quote for your built BBO as he probably included billet parts for the torque and more of a race build. If you click the link he lists his current prices for the three build levels and what they include. The stick setup you went with is very cool though. As is your whole car. 8)
