Well, right on!
I would love to see some honesty in a direct comparo like that, instead of the usual one sided crap.
What do you think?
the Mopar has the widest Int manifold of the 3. That makes for longer runners for higher torque levels.
There's been much discussion about rod ratio's, and that it's supposedly not a factor.. Personally, I think this is an example of convenient 'blurring the facts', cause the shivi has the worst R/S ratios out there.
In the early 90's, I took a shivi camel hump (1.94 Int), a mopar 596 smog head (1.88 Int), and a Windsor Phord head (1.84 Int which I didn't like doing cause it's so small) anyway, all got bowl porting, back cut valves, and same valve jobs. The 596 won by 5cfm, and the phord shivi basically tied.
(put these heads as a display at my buddies shop, who was doing a promotional event. it was not a favored display by most)
Cost of the build is also a huge misnomer ... I don't ever see mentioned all of the ancillary valvetrain hardware the chevy guys have to buy (larger studs and machining costs to install them, stud girdles, and guide plates) all of which the mopar guy doesn't need. that's the turd that never seems to flush.
Some of the iron used in the sbc is terrible! I've seen ridges so big., that you might as well drop a 060 over piston in it.
I'm ranting... time to stop.
