318 with 360 crank-another peeing contest
damnimcooltom i do understand that i have 4 of the 302 casting heads in my garage. i just curious why this 318 head is such important ? what can i do with it
There the best flowing 318 head and the best when ported. There the last head to be produced until the Magnum head came out. The "302" head can be ported out to approx. 240 cfm intake. with a good balance possible on the exhaust side.
For a 318 to have this much air flow on a small port is excellent and it will make for a great street strip possibilty. The problem arises when people want to use a 360 head on a 318. There comes the catch 22 of the big ports abilty to move more air as cast vs a as cast 318 head. The problem with a 360 head is the large port window moves air slowly and ineffectivly for a smaller engine and doesn't show itself well until the RPM's are twisted up high.
This is fine for a heavy breathing street striper or light drag car, but for a heavy street car it can make for a sluggish and poor running engine down low where the street car spends it's time running.
The draw for the 360 head is "Cheap Performance" (High RPM) vs. the heavy expense of porting the 302 head, which is far superior to use over a 360 head. The problem is getting people to beileve this and/or understand this.
(Even though MoPar proved it years ago)
They just see dollor signs in there eyes and throw common sense out the window and pick up the flag of "Frugal-ness" (AKA Cheap ***) and then try and wave the flag of "I spent less, WTF is wrong with you?" Crap.
Magna flux the bear and cleaned up head, proceed from there. PM if need be.
Now, back to the topic on hand.
