This is Al Corda's car. I just spent 3.5hrs talking to Brian Ebert who built this LS1. I saw the car in person, and saw the heads from the motor. Why is this car not included in the fastest f-body list? Another question: how they hell does this guy get around 450RWHP out of a 346 with a cam limited to .500 lift and unported heads. His technical knowledge of what it takes to make an LS1 fast is unreal. For one, he discussed how the engine makes best power with less duration on the exhaust, and less porting on the exhaust. His 409 LS1 will make 700 HP on pump gas. Any one heard of HiTech Performance in Minneapolis? Call this guy at 763-712-9088 if you want any tech info, or questions about any aspect of the LS1!!

stock eliminator. Can be driven on the street with legal tires. Whats the difference.... Still, how does he get this HP out of this car... I might have my heads ported from this guy for MUCH cheaper than MTI, ARE, or GTP. He was saying not to go with bigger valves on stock bore. He says I can get around 420 RWHP and torque with good idle.

driven on the street? PLEASE tell him to take it out and take as many pics as possible (or tape it). What to they run like 5000+ stalls? What kid of trans? 5.13's or something right? PLEASE take some pics!
Hey can you get some hard info/prices for me. Im always looking to try something new if the price is right. <img src="gr_images/icons/wink.gif" border="0">

Modified metric 200 transmission with Dynamic converter, GM 12 bolt with aluminum spool and rifle drilled axles, 9" radial slicks mounted on Bogart wheels. Aluminum block and heads, .500" hydraulic roller cam, Holley computer controlled fuel injection and ignition. Pistons, heads, intake, block, rods, and crankshaft are all stock. Thats right, heads are unported. For about $1500 he will give me heads that will get me to trap 117-120mph in the 1/4. Call him for all the technical info, or to ask questions. He's pretty nice. Brian Ebert 763-712-9088. He could go into way more detail than I can. Heck, I spent 4 hours listening to him talk about the ls1 today.

Not much. Both Pro Stock cars and Stock Eliminator cars (the competitive ones) are purpose-built race cars with purpose built, maxed-out race engines. They are not street cars in any way, shape, or form.
Very impressive, never-the-less.

id love to call, but i dont have long distance. <img src="gr_sad.gif" border="0">
arent the heads decked to raise compression? "unported" can go a long way.

Well if they are unported and using stock valves, then why would you pay him $1500.00 for a bone stock set of heads?

no,,,, $1500-1600 for ported heads with titanium retainers, my choice of valve springs (I told him comp 918's, or a dual spring, stainless valves, bronze( I think its valve seals or retainers to prevent the valves from sticking) That will produce more power under the curve, and equal or better the flow rate of any other head out there.

about Brian
Some of Brian's racing highlights include the involvement with the winning and top placing cars in the SCCA World Challenge from 1992 - 1998. He also handled engine management at the 24 Hours of Lemans in 1995, and has performed various services for Saleen, SMG Motorsports, Pirate Racing and Leighton Reese (now in Trans-Am).
More about the owner:
Brian Ebert began "playing" with cars at the age of 14. Whether it was his cars, or those belonging to his friends, he was continually trying to improve their performance. At age 16, he started drag racing and a whole new world opened up to him. By the end of high school Brian was working as a mechanic, which enabled him to learn about every aspect and system in an automobile.
Then, in 1990, Brian got into the high performance field with a job at Tuned Port Induction Specialties. While there, his duties included installation, Dyno operation and R & D. Finally, in 1991, he went to work for Doug Rippie Motorsports (DRM) where he remained until he started his own company. While there, Brian was involved in almost every aspect of car constuction. His responsibilities included , parts and engine installation, differential set-up, engineering and construction of race cars, and then moved on to engine building. Starting with LT-1 engines and progressing through to LT-4's, LT-5's(ZR1's), and lastly LS-1's. From cylinder head porting and cam development to EFI programming, Brian was instrumental in making some of the best performing Corvettes in the country.

1) Our lists are for the street cars of the members of this site (or at least somewhat streetable cars).
2) He probably runs a lot of compression, a lot of rpms, a very radical cam other than the lift, and at that level of racing an "unported" head can still have thousands of dollars in preperation work. I'm not saying it has ported heads, but I'm saying there is probably a big difference in his heads and the heads on a stock Fbody.

he will port the heads to match or beat any of the heads, no matter what stage. Flow #'s arn't everything. For instance, during development of some heads that flowed 600CFM, he had 2 pair of heads with the same flow #'s across the chart, but one of the pair made 100 more horsepower. The difference is in the angle's they were ported, and some other things I didnt understand. The point was, that everyone thinks that flow #'s are the most important thing, but while they're important, they are not the only factor in a good set of heads. I challenge any of you to call him up and ask him a question he cant answer.

I told him about the board. He might register. He is really busy doing alot of projects for people. BTW, you should have seen the yellow 409 LS6 vette auto cross car. Idled smoother than the B1 cam I heard idle, yet has a 111 lsa. He had also done the total programming of a computer in either a LT4, or LT5 vette to fully computer control a dry nitrous system. The computer would recognize the nitrous, and change the timing curve, and everything nesseccary that the computer would custom tune.

I'm going to call this "Brian" guy...God.
LOL, just kiddin.
Sounds like he does AMAZING work.
I may have to give him a call to find out some stuff about a cam.
Thanks for the info!
