Are the GU 4.5L Engines good or not.

[jay see]

Thanks, Plassy. Next question is if I got either a 4.5 or 4.8 port and polished and fit headers, would the electronic fuel injection be able to handle it?

I know that Carby engines benefit greatly from those three mods.

Don't know about the port and polish, but I've put a full manta exhaust system on without any efi issues.

Haven't done any fuel consumption comparison as yet.
