Has anyone seen an MPG gain from porting the exhaust housing on a 351? What about larger turbines? Any effect?
Love the way my 79 runs with it but daily driving mostly hwy id like to see better than 16 mpg. Been trying to stay under the boost and havent seen much change. Cruising egt is 750-800 and wraps out the 1600* pyro fairly easily
