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. I think the head casting number is
62426.
Best Regards,
Jim
