Well I haven't ordered the cam yet b/c my engine is still together with a smaller 248/254@50 solid roller now that runs 10.80's@127mph on motor but with the n2o converter. The mph and weight of car shows it makes about 570HP@ the flywheel now. I just bought a Victor EFI intake (fully ported) to replace my factory LT1 intake still on the engine along with a Fast DFI setup to replace the stock PCM. I still have to buy the new cam, crank trigger and MSD distributor to finish up my project. I am hoping to make close to 600HP with the new intake, camshaft, engine management and ignition system. I am also going to experiment with E85 and a 200+n2o once I get everything lined out. I will post some track times and dyno numbers sometime in the next couple months. i am shooting for low 10's on motor and deep 9's on n2o. Later

Cool, If you havent ordered the cam yet, give Harold a call. He is a really informative and cool guy to talk to..Very smart dude. He has a VERY long history of designing cams. Here is a short history

Since you asked, I'll give everyone a very very short history of me, so you'll know where I came from.
1969---Went to work for State of Mississippi as computer operator, rose to be lead operator at CDPA, Central Data Processing Agency.
1972---Began working on cam design program in my spare time.
Dec 15, 1972---Sold 310AP SBC solid to Reed Cams, Georgia, for $125.00.
1973---Made $3000 selling to Reed, Isky, Engle, Norris.
1974---Designed Reed's RxxxULX line of rollers, and a lot more, including Benny Parson's 1975 Daytona 500-winning cam. Also Shirl Greer's TF/FC NHRA National Champion Nitro Funny car cam, designed for Norris, and it was a True Chrysler flat tappet, with .438" lobe lift.
1974---Became General Kinetics' cam designer, worked with people like Bill Jenkins and Jack Roush on the cams for their ProStockers.
1976---Jenkins wins Pro Stock Natinal Championship, with GK doing large-barrel cams.
1977---I start in January with Competion Cams, as their original cam designer. Over the next 3 years, I design them hundreds of cams, including the 268 High Energy. I introduce them to the unsymmetrical cam.
1979---I write them their 1st in-house cam design program. Before that, we shared a program with Cam Dynamics.
1980---After negotiating since late 1976 for some stock ownership in Competition Cams, I leave and start UltraDyne on April 1st, 1980. The 1st month I design the 288/296F5 and the 288/296R6, the 2 most popular cams I ever made.
1981---In September, I hire my 1st employee, Mike O'Neal, who ran my shop, made all my models and masters, etc.
1982---We're running 2 shifts, from 7:00 AM to 12:00 PM. Tim Goolsby comes to work for me, he is Mike's brother-in-law. I also design UltraDyne's first hydraulic cams, such as the 272, the 276, the 288/296H.
From then on until 2000, we all just worked. UltraDyne grossed over $1.2 Million a year from 1990 to 1999.
2000---A number of independent factors began to take their toll---Federal Mogul acquiring my 2 major solid lifter core manufacturers, and their later Chapter 11, Lifter companies disappearring, tremendous cash-flow problems in the end of 2000, initially triggered by the UPS strike---We lost around $50,000 in the strike.
2001---A un-named cam company in Memphis hires 8 of my 12 employees, and 2 more just leave because they think --that's it. Only Tim and Gail are left with me.
2001-2003---UltraDyne is in the Chapter 11 'Death Spiral'. I take a $0 salary for 2002, and pump all my, and my wife's, retirment money into UltraDyne, along with all the equity I could get on my house, etc, etc, etc.
June 2003---Everything is gone, the government locks the doors.
August 2003---I go to work at Lunati, charged with completely re-doing their entire line of cams. Mike is already there, waiting for me, along with Steve Slavik, who worked for me for 13 years (Mike for 19...). Then I meet the corporate world.....
Oct 2004---Lunati introduces the VooDoo cams. And they really work good.....

This has been the line and times of a cam designer, and even with the down sides, it has been the time of my life, and I'm going to stay at it as long as I can.....

No comments are necessary, you are all a great bunch, and as that Great American, Minnie Pearl, said, "I'm just so proud to be here!"

Thanks,

UDHarold


He does free lance stuff now, and his design cams are ground at Lunati. I just got mine in yesterday. His number is 662-562-4933.

Most other heads of the same size flow that at a lower lift. Not saying Dart is a bad head but usually AFR and Brodix make more power than a Dart but not a drastic difference. I was told by my buddy who went to Joe Mondello head porting that a Dart head is a head porters dream in that there is plenty material to work with in shaping the port. He just ported a set of Dart 355's for our friend's car with a 632 BBC and the car weighs 3550 and it went 9.0 letting off. I don't think you can go wrong with any of the three heads mentioned here, you just have to know what you are looking for and do research.

dont sleep on the rhs heads either..there a good head also and know of a couple running 5 teens an up on 275 cars..

the new profilers that chad an dr j do look killer and run killer..im waiting to see what they do in a all out race engine.

you cant go wrong with dart 227s or 230s with port work

an brodix -11s and trk 1's are also killer..

i know your pump gas and now all out but i always like to look at what a head can do all out also because where all speed junkys and down the road we might just want to up the level and theres no sinse of buying parts twice.

Thats the nice thing about the Pro-Filers.., and one reason why I went with them over the CNC track 1.. If I wanted to use them on something bigger, theres TONS of meat there to to open them up.. I think they can be opened up to 250cc runner or something....Chad is a stand up guy, and he really believes in the Pro-Filer 210..

I could be wrong but with 11.0 cr I don't think you will see the absolute most potential out of any head larger than what you have. You deffinatly made a good choice especially if they saved you money.
