hello i just installed the 48 ida webers on my 347 stroker, 205 cc afr heads , MSD, 514 hp.
i had a set of autolite app 3924 but they look low quality and rather fouled .Should i run a hotter or colder plug..? looks like it need a hotter plug.
Any one out there have a great plug for a high performance small block with webers..?
cheers paul.
