APRIL HOT ROD; 360 Magnums

Pretty informative article on (their opinion) low-dollar hop-up of a 360 Magnum 300HP crate motor in the April 2008 issue of Hot Rod.

Basically, they flow-tested stock heads vs. Edelbrock alum. heads, and then dyno-tested a 300HP crate 360, and then replaced the cam with a .565" (!)-lift Comp cams modeaate-duration bumpstick, and installed an M-1 single plane manifold and a 750 Holley-style carb (Demon?), adding Edelbrock aluminum heads, since the stock heads will run into trouble at valve lifts much over .500" (valve giude boss interference.) My cam lifts .525" and works okay with those heads, but I think it's at the limit.

They picked it up 125 HP with those 3 items (cam, heads and intake/carb.)

Interesting article. The flow information on the two differeng heads was particularly interesting, I thought. The stock-type cast iron heads were assembly-line items, not the R/T. Intake flow was only a shade over 200 cfm... I think the aluminim version from Edelbrock beat the stock heads by somehing like 50 cfm., which is about 25 persent.... Impressive, I thought.

Now, I have to start saving for some... damn....
