Like the German engineer says on that TV comercial, "THIS CHANGES EVERYTHING!"
I thought that it was the RED machine! He was at the mid 12's at US 131. Wonder what he did to get 11.9's. A diet of late? Yes, it was the LAST year B body and the 64's can move if done right! He is weak in the carb/cam/gear area. Other than that.....nice hardware!
I'll bet your squirming for 11.9 second barrier answers Dana! The REAL question is Dana......ARE YOU GONNA BREAK THE 11 SECOND MARK? Tony P.

It soitanly does! I shoulda looked up the specs for wheelbase & weight before guessin......forgot about that car being a "B"....if you figure in say, the 4200lbs Clair mentioned, then my prediction would have been closer.....12.85-12.95.

Yep, low to mid 11's....and I will tell you exactly how! Go to a 825 to 850 CFM demon or Holley carb. Double pumper mech. secondaries preferred. Up the compression to at least 11 to 1. Up the cam's lift and duration to the next level! Up the gear to a MIN. of a 4.10 to 1 ratio. Drop a few hundread pounds.
His cubes, intake, heads, headers, and the MSD ignition are great parts to his 470 size. His stall speed is perfect! He lacks more gear to shove that "heavy" B body. Drop to about 3,500 to 3,600 lbs RACE weight. No NoS needed here to hit low 11's! We are talking about people here who KNOW how to build and match drivelines WITHOUT that cheater gas!
The car is an areo-dynamic "BRICK" to push at 113 MPH and up. He is good now for high 11's indeed! I'm running M/T drag radials pulling the same 1.73 60'. They work aired down. Make these changes and see him down in the low 11's! Tony P.

Time for "healthy" debate! I have ta' disagree with you 496 on a few things!
The "RPM" intake is about used up by the high 11's as Dana and I can clearly see! The RPM is more of a Street/Strip intake. If you want LOW 11's, the Dominator may get it there, but the RPM DUAL PLANE was not made for that area.
Actually, that stall is great and a 4.30 gear would be even better for LOW 11's.
Eddy heads can get you in the low 11's, but with some mods. His cubes (as you get closer to 500 ci and up) require way more cam and head/intake to breath.
His header size is perfect for big cubes....go fast power!
I say....stick to my plan!
It would be COOL if you and I could add our ideas to his car, one at a time, and see who gets to the low 11's better! Don't cha' think? Tony P.
These heads are great,only need to shave them to up the compression. Junk the cam.Roller only,cam manufactuer recomendation only! Indy heads?why not Indy intake?.850 cfm yes,but why not throw on a TQ modified by Demonsizzler.com.Dare to be different.Tony hit it right on about header size and i would agree the 4:30gear is the way to go.Actually with the setup he has now and the power he's making,I would concentrate on the 0-60 times.As they say"If you're slippin' in pig s...rap,You'll never catch the pig".Don't let that .509 cam fool ya though,it's one of the best budget cam's out there,but not for those heads!Glen

If the motor TRULY makes 547 hp @ 5400 rpm, he does not need to make more power, just needs to match it to the combination.
Is the converter truly stalling @ 4000 rpm? Even 4000 rpm is low in my opinion.
The 113 mph is telling me that the motor is not making anywhere near 547 hp.............
The biggest thing I see is a mismatch of cam to heads. The velocity with those really big 440-1 heads is WAY too slow with a .509 cam............
Yes - - the .509 cam is a good cam (at least the old ones were). I went 11.70's with similar weight, maybe a tad bit lighter with the .509 cam and poorly home ported 906 heads.
Would be nice to have a bigger carb, but that should not be the limiting factor at this time.

Oh boy! Where do I begin! Glen and Bode make some good points, but I do not agree with everything said. Let's try to clear this all up.
According to the "Mopar Performance Bible" I have, to get a Mopar in the 11's, you will need (for an RB engine) a 3,500 lbs MAX car, a 4.30 gear and some stout engine parts. SS springs are called for also. The book does not give a specific BHP number, just the parts needed.
The book says to go 10.90, your car must have a MAX weight of 3,300 lbs, a 4.56 gear, an M1 single plane intake, and 11 to 1 compression MIN.! Now they still say a 750 Holley. A 750 may work on 440 cubes, but get towards 500 cubes, the 750 is hurting you. Big cubes require more air. An engine, after all, is an "overglorified" air pump. More cubes, more air moved. A stroker requires a bigger cam and carb with bigger headers to move air.
Bode, look at the "fastest C body" list. Look at Joe Schmall's Fury running low 11's. Look at SportFury440 (Dana) and TONYPRO (MY car). What BHP do you think we are running? He is 111 MPH and I am 110.5 MPH. My engine builder (Muscle Motors) claimed 550+/- BHP. I highly do NOT think 550 BHP will get you low 11's no matter what driveline you conjure up with a 3,800 lbs "RACE WEIGHT" that the 64' has.
His 60' at 1.73? Not bad at all. If you are running low 11's, that 60' will be a tad lower or you have wheel spin issues! That or your making up time at 1/2 track and up to get LOW 11's! I believe his DYNO numbers are legit.
The guy said currently 12.20's regularly with a best of 11.90. What was he running at temp wise? 50* air temp. Heck, at that temp, I could shave a few 10's too if my rubber stuck! That part has me curious! Tony P.
