I built my 468 with Edelbrock RPM performer (oval ports) for a street strip application.would i have been better off with rectangle port heads
Because he's a moron.Ed , why do ya' always have to come along and kill a thread.
Did they have a race at Cecil associated with the Eastern Mid-atlantice Chevelle show?Bob, the "idiocyncracies" of each combo will tend to make generalizations like " ovals are always better" a bit too trite and very inaccurate.
BTW, since we're speaking of fast street/strip AND I;m always thinking of red 68's, let me please introduce the car I gave an award to at the MCC show:
Now, suppose these awards are always car AND driver, or, what the design criteria of the driver is...
Y'alll see that 11.55 in the second pic? This 68 DRIVES 1200 miles at a pop, lays down 11's, and drives home.
:thumbsup: :thumbsup: :thumbsup:
That is exactly why Mr. Bob Wilcox, of the great state of Marlyland, got the Can Am best of show award at the 20th MCC/ACES show, dubbed the ROAD KING award! You might have seen Bob's ad in Chevelle World.
Not taking anything away from any other red 68 Chevelle! This, to me, epitomizes street/strip. No power adders, no fancy efi/electronics. A very well engineered car whose owner is both a drag racer and master mechanic. If you're a fan of " Two Lane Blacktop ", and reckon this is exactly what muscle cars meant back in the day.... xcross country jaunts stopping at dragstrips/street races along the way, man o man, did Bob hit on a combo!
Wonder what heads Bob uses on his 68 bbc ride?
For the record...So Ed, seeing as how your zinging the thing to 6800 for the 2-3 shift and I go back and read your old posts about keeping Rpms to a safe BBC zone are you willing to change heads to low chamber sized rectangles and see it find that 9 you have been chasing for ten years? Ovals or rectangles----- the simple thing is that it comes down to flow and its direct relation to port velocity... if you wanna play on the flow bench in the shop come on up-- Math is a pretty solid theory to test with.
for the record, I had to slow mine down this winter because I dont want to cage it-- but still run 11.50 on the hottest day of the summer on pump gas. And yes, I do that with a little 461 with rectangles and all around your 6800 shift point...
So not every one on the boards wants to limit their parts to meet your criteria.. Ovals ARE great---- but that doesnt mean rectangles are the junk you stopped playing with ten years ago.. Go back and read your master recipe---LOTS of changes since some of your original posts-- seems its okay for you to try stuff and then use it but your bored with everyone else that does it...
My agenda isnt to start a fight-- Only to point out that thinking outside of the box is WHY ours cars are better today then they were 30 years ago.. Additionally, if we encourage guys to think outside our box they will make them better again.
