How would stock Opel 1975 fuel injection compare performance wise to a good Weber 32 36 on a redone 1.9 liter with 9;1 pistons, mild cam and maybe just upgrading the valves to 2.0 intakes and exhausts? It would be in a 1975 Manta so the efi hook up etc should not be a problem. How tempermental was the efi, because I've never had a 75 Manta before.
I picked up this Manta with 26,000 original miles, original paint (not perfect) and egads! original tires! The efi is in the trunk. The car was in heated storage for 30 years and they put a carb on it to get it to run...at all.
