[Gmecm] TBI for 455 Olds

[Wade]

Exactly right about the scarcity of the 500 Caddy engines.  I have two ? one is completely rebuilt with some performance goodies sitting in our 41 Buick and the other is a core.  Our 455 Olds is in a 1946 Olds custom.

 

I would like to find out more about which distributor to use for the TBI.  I am looking at the link for converting my current HEI in the OLDs to a distributor that will work for the TBI?

 

I know that I can do this ? there must be a way.  Short of having a special one built.  The small diameter distributors that the TBI would use for GM has the guts?  I have a number of those lying about.

 

Thanks to everyone.

The 455 Olds are getting harder to find.

The 500 are even harder to find, so those swaps have not been popular for the last 10 years.

76 cadillac 500ci  was the first yr  of a gm EFI system  -but they dont fit a olds 455.

  lots of guys who own the GMC FWD motorhome swap out the 455 for a caddy 500.

Greetings all.  I have a few general questions for the group:

 

I have a 455 (a 1976 model year engine) and 700R trans (non-electronic speedo gear) installed in a 1946 Olds.

 

I want to install a TBI setup on this engine and was wondering what kinda Ignition (distributor) could I use ? it has an HEI (stock) on it now?

 

Also ? I?m thinking about using the computer programming from a 454 ? either an SS model or a pickup. Would I be within performance parameters (I just want a good driver ? no performance camshaft but with an aluminum intake).

 

And, finally, what would you all suggest as to the fuel pump to use?  I?ve converted other cars over to TBI but have always been able to use the distributor from the donor vehicle.  In the case of my 455 ? there are no donor TBI units that I am aware of.

 

What are the thoughts about my project?

 

Thanks.  Wade.
