Porting 460 exhaust ports- how far can we go ?
As can be seen from article at FM front page, 460 passenger car intake ports flow very respectable amount of air even in stock,unported form.Near to 300 cfm translates into roughly 600 hp potential.And this unported.
But the exhaust ports are the real problem here. How much can the shortside radius and the roof( the area around the valve guide)be worked on without the danger of making a hole to water jacket?
I am building a street 460 for a buddy´s 65 Galaxie( 10:1 compression, CC 292 Magnum hydraulic cam , Weiand Stealth intake and 1973 pass car heads (decked, new guides, adjustable valve train,guide plates)larger stainless exhaust valves).
By the way are the exhaust port plates still widely used ?
