I'm trying to find out the best (IYO)flowing factory iron oval port head with a gasket match-clean up the pockets and 2.19&1.88 valves, cam lift in the ..500 to .600 range,nothing special (open or closed chamber). It's for a 6000 rpm 454 street engine in a 3500lb car. Thanks Mario.

FYI, through the end of the 2007 season when I retired my 468, there wasn't one 468 with 049/781 heads installed in a similar weight Chevelle, competing in Division 1 brackets that could run on par with my ride no mind quicker.

Matter of fact, my Chevelle ran quicker than EVERY n/a 454, 496, 502, GM's 720HP 572 and most 540's regardless of which head they ran, in a similar Chevelle here in Division 1 brackets, just saying.

BTW, the devil is in the details and the performance that HP Hunter speaks of also comes by way of a $6,000 Coan XLT 350 trans backing up that 496.;)

Just saying.:D

I didn't forget anything, you forgot to be truthfull AGAIN in another post whose sole intent is to solicit business.

FYI, that trans sells for $4,000 - $5,000 USED...

That said, don't know, don't care who your customer is, "what is full weight" and "I think" is meaningless speculation, besides it appears no one in your area has ever seen your car run, no mind back up your claims...

Per Mark Guthrie, a guy that first met HP Hunter aka Mark Jones in 2007, knows him well, and "helped him in his shops for months", "Mark has talked about his "3600 lb. Chevelle" dozens of times. I have never seen him run any of his cars, ever and I am just saying none of the locals have seen it."


Meanwhile, Bob's Chevelle runs good, it should, it's nearly 300 lbs. lighter than my '68 and has nearly 40 more cubes and I've been advising him for over a decade.;)

Again, nice to see that after 5 years, some have caught up and some have surpassed my former Chevelle's performance as is the case with the car HP Hunter speaks of, even if it took 30+ more cubes, a light weight, low drag transmission in a car that weighs nearly 300 lbs. less and last but not least a -1600' DA to do it!

Just saying.;)

BTW, the compression ratio of this 496 is at least 10.8 not the 10.7 you stated.

Just keeping it real.:D

You ain't much faster and again, it's YOU that is trying to prove something, chasing the performance of a car that I sold 4 years ago...

http://i381.photobucket.com/albums/o...r/p1010004.jpg


that never was built to run in the 9's, hence no rollcage, though it did, with a restrictor plate having 1 1/4" bores under it's 4150 carb...

http://www.youtube.com/watch?v=rbKYio6OvKM

it also ran 137 MPH.;)

meanwhile let me know when you and team cluless run in the 8's, run 150+MPH and 60 foot 1 teens no mind a 1.17.;)

Save your claims and sales pitches for team clueless. I ain't impressed and could easily out run team clueless's mascot with the same cubes, backed too with a $6,000 trans, at the same weight and in -1600DA air.

yea, we always have negative 2000' air in June at ETown.:rolleyes:

Like I already stated, misinformation, half truths and LIES is what your posts are all about.

here you go, 2 months earlier than the ETown run on June 15(video) at Island dragway whose actual elevation is nearly 500 feet above sea level. Note as well the weather stats, DA, fresh oil and that I had 8 turns in my restrictor plate with each turn being worth .04 in ET. FYI that run like all my runs in competition was DEEP staged too. .09 quicker in all the incrementals shallow staged meaning it's a 9.80 pass. Now open up the restrictor plate and it's at least a 9.50 pass at 3870 lbs, with 26 more cubes backed by a nothing special $1,100 turbo400 and in 2,700' air!:p

Mr.Lee, the op asked a question of a group he believes knows best yet you want it dismiss his question and relegate it to "The Lounge" because you deemed it doesn't even remotely relate to Class Racing. Way to go, another example of that elitest attitude that some, thankfully not all class racers demonstrate..:rolleyes:

I ran these heads on a pump gas 468 from '95 to 2007 and each time the engine was freshened, the heads were massaged a little more. Ultimately going from a 2.19/1.88 valves to a 2.25 intake valve. Best numbers in my 3880 lb. footbrake launched Chevelle were 1.28 60 foot and 10.07 @ 131.
