How many hp. is the 383?

Remove all the SD crome and send it to me. That will make it faster. Can you post some pictures of the car and the cowl tag.

I struggled with the same dilemma for the last 2 years trying to decide whether to keep the original 350 (which runs like new) in my Laurentian or to swap a BBC. I finally got fed up with myself and have decided to do the swap. The worse case scenario is I hate it and put the 350 back in..

If you can afford the motor, give it a go.

I really want to keep the classic feel. How would a done up 327 powerglide perform against a budget built 383 turbo 400 (wish I could say what s in it guessin nothing to fancy

I think that if I was to change the size I would go all out and get a big block.  I have guys tellin me to go with the stroker and save the 327 in the corner of my garage but that doesn t make any sense

Depends on how you drive it!!   Cruising to shows, and back home, would not notice the difference

Want to smoke the tires, and run up through the gears, and race it... 
The 383 is a little better.. 

"Most" of the cars on the site are never driven aggressivly......

The 383 would be a world of difference compared to the 327. Like others have said, if you can afford it, do it, you only live once. The 327 can sit on a stand until you are ready to put it back to original. Heck, the 3 speed auto will even make the 327 feel like a different engine.

I have to edit my post. My opinion depends on that particular 383 being a good engine.

For $5500 I would expect more than a mild 383! It better have good components, even a roller drivetrain at that price....assuming this is a used engine? How fast do you want to go? Are you willing to do suspension mods and buy some drag radials?? If not, having lots of power is not all that useful, you won't be able to put it to the ground. Cubic inch's is generally the way to go... the 383 all things being equal will out perform the 327. There are some nice 327 combos out there, but be prepared to spin it high and reduce the longevity of that engine to put out what the 383 will do at lower rpm. I'd say if you want to run solid 11 or low 12's you are better off with a new combo...

I am sure the 383 will make that car rip but you should think about what you want to do with the car. A lot of 383 won't run on a mechanical fuel pump because they are fuel pigs. You might have a electric fuel pump , a return line to the tank, and might have to run gauges to moniter fuel pressure so you don't lean the motor out. Personally your car looks great in the photo and probably gets 20 MPG on the Hwy so why would you mess with it. If anything change out the powerglide for a th350 because that will make that car jump. I would love to see more pictures!

Paul, there is no need for an electric fuel pump for a 383 or big block for that matter unless they are extreme builds. I used a carter 172 with my 406 and it was about 475hp. I have a holley mech. pump on my 496 which is close to 600hp and it has no problems feeding it. As far as being a fuel pig, it could be if you have a heavy right foot..
The 3 speed auto will make the 327 feel like you gained a few ponies by itself though.

I'm going off of a buddys 420 and his 383 but one is 500HP, the other is 600hp, and he drag races them so if your just around town the mechanical was fine but in a quarter mile he said it would lean out and GO BOOM! Both of his are pretty built so I imagine if you had a lesser one it would be fine. I persoanlly don't need that kind of HP and I'm not a mechanic so there's probably many ways to go with a 383.

 

 

I forgot to add MORE PICTURES PLEASE OF THAT 65 SD. PLEASE, PLEASE!!

65sssd - Is your friend running NOS? If yes, I suspect that may explain the 'leaning out' issue, and a 383 with 600 HP intended for the 1/4 mile is quite possibly getting a little help...


Back to the question. One of the nice things about the SBC is that they all look pretty much alike from the outside.

I am running a 350 in mine. The original 283 is wrapped up and stored under my workbench. Also stored away is the original powerglide. Of the two, swapping the PG out for a 700R4 made the biggest change in driveability. Lower first gear & overdrive make a huge difference off the line and on the freeway.

I agree with SD421. Put in some 373's and swap the PG for a 700R4 or 200-4R. You'll be amazed with the impact. Then pocket the difference. When you get tired of that, you can build a 383 (or buy a 400) and get another shot of performance. That will last a couple more years, then you'll be looking for a big block and you'll need a 12 bolt and a beefy trans and... No such thing as too much power.

I also agree with those who say "It's your car, do what you want".

I agree with SD, put your $ into a 700R4 or 200R4, a set of gears and put the change into the 327 and you will have a great package. Then you will be set up to go 383 later and will have a great drivetrain to back it up.... build your own 383 unless you know the builder...
