[QUOTE="SpookSVT, post: 3780498, member: 34120"] [b]Cams and revving past 7500RPM[/b] I'm giving up on the team contour guys so I'm just going to ask around here. This engine seems to be of F1 design, short stroke, oversquare (3L), DOHC heads, and likes to rev. So this is basicly what I want to do; high compression pistons, headwork, cams, and rev the motor. My questions are, how high can you reliably rev this motor and can you make any improvements over the SVT cams for more power up top? This car has to still be reliable and drivable as it is my DD. I'm keeping the secondaries and going to lighten the flywheel another 2 pounds and If I have money go back to the stock 4.06 FD ratio. All this to keep it drivable. The only things I see holding this motor back is a nice set of cams and the intake manifold. The cams just need to hold the TQ curve a little higher and longer than the SVT's. The thing is I need specs. DemonSVT, I know you know a little bit about cam math, could you possibly help me out? The manifold while good for making good lowend TQ and such a flat TQ curve is holding the car back up top IMO. I'm willing to sacrifice a little drivability to make some crazy highend power, where all the fun is at. I was looking at the SHO designs and thought they would really work well on the duratec. A single plane oval/tubular upper. The heads would be converted oval ports to accept split port manifolds. If anyone can help me out here I'd greatly appreciate it. [/QUOTE]
