Mindgame exactly its combo and tuning...it all has to come together its not one part or the other its the whole package and how one compliments the other... I'm glad somebody realizes peak flow doesnt hold a candle to lowlift and port velocity..

Looks like everything I know(little that it may be) about LT1's or SBC's for that matter could be totally wrong if you were able to accomplish that!

Congrats Gary! That is awesome! Just make sure you keep your vert top up when you cruise around, you got enough power now to blow that hair off your old noggin.

Cant wait to see you and James running at the track.

Congrats on the numbers. I'm getting my H&C package dyno tuned in a couple of weeks and I'm shooting for similar numbers.

I usually don't disagree with much you say, but where does that come from? Hell, if my car dropped 700 lbs, I'd be running almost 120 in the 1/4 with a stock motor and headers. My friend's stang ran 135 mph in the 1/4 with 420 rwhp. How? The car only weighs 2600 lbs! Weight plays a huge role. How do you think those 250 hp hondas run 118 - 120? They weigh in at 1800 - 2000 lbs.

That is one stripped Honda for them to lose 800-1000 pounds. I have seen little cars try to run the 1/4, and in general most people can't get them to hook. Since I live in the land of 2000-2300 pound RWD cars, I feel I can say that quite safey. Some guys hook, some dont. If his car lost 250-300 pounds to bring it down to a lightened hardtop, he's not goin to lose even .4 which is not going to be a massive MPH difference. Of course we can get into gearing as a possible reason too.

Joe,

Like I said before you should post here a bit more cause you are right on the money.
My take on it is this..... everyone just has to have a head that flows 280 cfm. They don't care if that's what the motor needs, they just want the big numbers. The lift is the other thing. The "higher the lift the better" crowd has more members than a fire-ant colony. Yet I haven't seen it to mean as much as they seem to believe it does. Like I said before, look at this Engine Masters Challenge that took place last year. God knows there were alot of high velocity cams in that contest, yet the guy who won the whole shabang won it on an old Isky grind with the same lobe on the intake and exhaust. Go figure.

-Mindgame
I think that Joe gets a kick out of reading more than posting. We joke all of the time about the flow #s tossed back and fourth on here. I think that some of the "experts" on here seem to know everything so why add his 2cents? After all, he's just a country boy from the stix I've really got to thank Joe, almost everything that I thought I knew about LT1s was wrong. The internet is a very dangerous thing.

Mindgame- you seem like a class act

Say LT1/LT4. Im just wondering if they are rediculous low lift numbers or just better than what is usually done. Seems from what he says they would stall around .550 or so lift...

never said they stalled , they carry on up to .650-.700 depending on what heads you working with they just dont fall off or get turbulent above .550 my personal heads stop climbing at .650 BUT, i can bottom the valve on the seat and it doesnt fall off either flow stays the same and not turbulent..about .900 lift if you wondering...ideal flow would be pure speculation on what it should be. intake,and header will hender the best flwoing head if not mated properly to the application..purely duplicating of certain numbers at lifts wouldnt make it as good or equal to another head....

Eric has a badass whittling stick he uses on his heads, and Joes uses special pressure treated lumber for his cam cores, rotating mass reduction is his key to power. Lose the BS, and go faster

When yall gonna be ready fr this set of LS1 heads sittin here?
