Hi All, Quick question: After modifying the ignition system, is there any logical method or rule of thumb for changing the factory-recommended spark plug gap? Engine in question is an '86 Corvette 350cid V8 engine with [305 heads] TPI, HEI ignition, headers, high voltage coil, "performance" 8mm plug wires. If anyone can shed more light on the effects of the 305 V8 on the 350 block, I'd appreciate that as well. Best Regards, Jim

Burgerman will be along to tell you shortly :)
Unlikely, as this is a UK group !
I'd be very surprised if the stock gap for the 305 or 350 wouldn't be sufficient to give decent ignition.
and we dont get chevrolet engines over here do we nom?
Not '86 V8's in common places, no.
In article , snipped-for-privacy@gnt.net spouted forth into uk.rec.cars.modifications...
The general response you might is "if it isn't an Alfa/Toyota/Rover/Turbo/Straight 6/4x4" it's s*it then innit.
And only Fords with V6's and at least one Turbo (oops that will upset Dervy) and RWD or 4X4 need apply.
Aaaaaaaaaaaaany minute now :)
V8s ? Not that I know of ?
