how much more compression? im aiming for 9.0-9.5. What is necessary to make the intake work? This is my first engine (obviously), and my dads not a car guy, but he is into woodworking.
Iron magnums are good for a max of 10:1 on pump gas. Because of a double quench chamber and a fast flame front they like lots of quench.About .034 should do it They also like a single pattern cam as the exhaust really needs no extra help from the cam.It's almost too good. In many cases guys run stock 1.6 ratio rocker on the intake and a 1.5 on the exhaust to try to maintain flow balance at 75%. I would use a magnum pattern eddy air gap as the magnum has no heat crossover and the intake will run very cool.The other option is to drill and tap the mags for la intakes.Then you have the best of both worlds available.
