I cant decid if I want to go with my dellorto or a Holley 600. On a 90 13B with a holley blue fuel pump ( just order from summit). Which one will pull more power? The other question I have is do I have to go with the Holley 600 that Racing Beat offers for $620 or can I get it from summit as well? What about the OMP doesnt it connect to the carb

 

the holley's racing beat sells are specially setup for rotary applications so I would suggest that you go thru them for the carb.As for your OMP I had to bend the rod and put a couple of new pins in to hold it firmly against the carbs throttle linkage.I'm not quite sure if the holley puts out more power then the dellorto.I think in the low end it might seeing as the dellorto is a big 2 barrel and the holley is a 4 barrel but in the high end I think the dellorto has more.

 

Remember you could always ditch the OMP and pre-mix if you wanted.

 

I have heard that because of the way the Holley's float bowl is set up, they are best for drag racing only. The Dell'orto would work better on a road course and on the street.



Perhaps someone could confirm/deny this?

The holleys racing beat sell are made for all purpose use but I haven't had any problems with my Dellorto tho.I guess it's just a matter of personal preference when it comes to carbs.
