I am rebuilding my sbc and after reading Dennis Moores book I am considering using an intake gasket that would block off the exhaust crossover. How much of an effect on cold starts will this have? How much performance will I gain? My 350 has been bored to .30 over, balanced & blueprinted, 441 heads 202 & 160 valves
polished, might be ported? comp cam 270H, Performer intake, Edelbrock 600 marine carb, Msd ignition box. Stock exhaust.
I boat in Northern Indiana & normally boat in 70 to 90 degree weather.
The sbc goes in a 1986 22' sea ray pachanga.
Thank You
Scott

yes sir seeya use one of thier dual pattern cams with a larger exhaust profile and slightly larger intake profile the 270 is on the small side ..
Also in a boat the cross over is 50/50 leave it or take it out I've never seen any improvement or loss due to it..
hope this helps you fly
