I'd say 35-45 extra ponies over stock with what you have set up.

I was under the impression you should stick to a modified nikki or with a holly if you didnt have any porting done to your engine. does the deltro add that kind of power with out having the driveability drawbacks of the webbers?

Dellortos are suposed to be more "streetable" yes.



the combo of a full exhaust and carb upgrade is what'll net you 30-40hp over STOCK. not just a carb upgrade.

Looks just like mine. Nice buy. Robs a great guy.

I have yet to get mine running. Watch your fuel pressure (4 psi, no more otherwise you may take out your needle valve) and make sure you have a good gasket between the lower intake manifold and the upper. Those are some of the issues I have just ran into when installing mine.

Good Luck.
