WANTED 455 or 403 Olds engine

[Cuttywhtnite]

I'm looking for a good 455 or 403 olds engine for a 78 cutlass. I have a built 200 4R and the car currently has a 260 engine. I'm located in Houston.

Just sold my bitchin 403 long block or I would have posted it up for sale here. Good luck with your search

Thanks Anubis, my sons want me to put an LS in the cutlass but I've been resisting.

I like this a lot and Olds power or no power is my moto. I also have a 2004R with a 260 and 3.42 gears, both help. Get at least dual exhaust on the car. Sounds better and helps, don't be scared to through on 2.5" pipe. I had 1 5/8" Sanderson Shorties with 2.5" dual exhaust with a compact X pipe. If I had even a slight stall it would have left rubber and pulled strong through the rpms, it didn't feel like a 260. I took it off but I am putting it back on, currently less than 2" dual exhaust on the car, decent off the line but really struggles past 3000 RPM, the 4200 RPM shift point sounds really labouring for the poor baby Olds. So put the 2004R in with 3.42 or 3.73 gears and add your dual exhaust and headers if you find a 350, don't rule one out, especially with the new 4" stroker crank or a 403. Then you can take your time building the motor and still have something that will get out of it's own way and get good mileage doing it. Good luck with your search, c'mon local guys help him out.

cuttywhtnite, let me check around my father in laws. I had a good 403 covered in his barn. May still be there if he hadn't got rid of it. As soon as I can get out there, maybe Saturday morning, I will let you know.

 

[Cuttywhtnite]

Thanks SupremeSpeed, is it a complete engine? I've got the car tore down installing an 8.5 with 3.42 so I've got plenty of time.

Last I saw, it was complete. If anything it may have the intake pulled apart. I will go there tomorrow. I took the qjet from it.

Let me know if I can offer any more help with your LS swap 😎

 

[SupremeSpeed]

Did you find a 403 or did you decide to do the Ls swap?

Topshelfmopars has a 455 but I haven't gotten over to look at it, I'm in San Antonio for an API winter Conference meeting and got to be in Austin next week. Looking for a complete motor, the 455 doesn't have an intake, carburetor, or front brakets for air, alternator, or P-Pump.

Sounds good. That 455 is a better choice.

Edelbrock Air Gap single plain? A Victor?
