Did the old list make it over to the new board? I cant seem to find it. I am searching for an LS1 346 with STOCK Unported heads and a hydro roller cam running 9.99 NA. Does such an animal exist? I would like to see the list make a comeback soon. Thanks for the Help. Bear

 

9.99 NA? I dont think so.

 

Yes such an animal does exist,its the car of AL Corda and it went 9.97 I believe. It has stock unported heads and an Ls1 intake I believe. Its also a NHRA stock elimanator car,the record holder for A/FIA. The car is tuned by a place called High-tech motorsports.

 

What casting head? Surely not off the rack GM LS1 casting. If so, Please sign me up for his combo!!

 

yes its a gm casting. you should check out the rules for those stock and super stock classes. very interesting. and i thought Al tuned his own car. i do know he runs the Accel dfi. i saw the write up on him in national dragster after he made the record run

 

Those are awesome times no doubt but if you think those heads have had ZERO work done to them...

There are tricks done to the valvetrain to make those "hydraulic" cams function pretty much like solid lift cams too. JFYI

 

I don't know for sure, but I heard they are $30,000 dollar motors that have been gone over with a fine tooth comb. Al set that record the first race of the year,but haven't really heard anymore about him this year. Is he still competing in the NHRA series,or is he sitting out ? Anybody have any info on him ?

 

Good greif, are you joking? I would NOT call anything on Al Corda's car stock for anything but NHRA's class designation.

 

I see it's time again to dispell some myths about Al's car.....
for starters, Al went 9.97 @ 131.84 MPH at the '03 Winternationals in A/FIA (2925 lbs w/driver @ 342 NHRA factored hp). The cost to build one of these engines from scratch is about $12,000 including the EFI and ignition system. Al is currently using a Holley Commander 950 EFI and Annhilator DIS ignition system but that may change in the future. The cam is a .500" lift hydraulic roller but duration and LSA are open..... don't ask what the numbers are because I won't tell...... however, we cannot put valve reliefs in the replacement flat top pistons so piston/valve clearance IS an issue. We have to use 1.25" valve springs and steel retainers, stock rockers and adjustable pushrods. We have used both stock hydraulic roller lifters and Schubeck modified lifters but have found very little performance difference between the two.
Colonel... the heads are out of the box 853 castings with bronze guide inserts, a good 3 angle valve job and the surface milled to minimum chamber volume by rule. They have NO cheater/hidden porting done to them whatsoever. They have gone through teardown and this fact was obvious to the tech officials who examined them.
The car DOES use an LS6 intake as came stock in '02.
The car gets it's performance because of many lightweight/ low drag components and more R&D time than I care to remember.

BTW - Al's car COULD run on pump gas but NHRA only allows specific fuels so Al uses VP C-11.

Brian,

I saw the car at the Memphis race. No doubt the car runs well, it's very impressive!



Great job at showing the world what the LS1 based engine is capable of! But it is far from what most of us here call stock.

 

Did no one get that Bear was attempting to talk ****...a carry over from the last thread.

 

Well, I guess you can say that's a judgement call, but how many guys here with fast 'street/stock' cars have a 12 bolt diff? A turbo 400? I'm sure those aren't 'stock' parts. Fact is.... while we may have a trick lightweight turbo 200 trans w/ a 5000 rpm+ stall non-lockup converter and lightweight diff parts, the modified 'street' cars on this forum have way more exotic components in the engine than we are allowed to run (i.e. - C5R blocks, stroker cranks, light rods and pistons, oversize valves in CNC ported heads, .600" lift cams, ported throttle bodies, etc.). The only 'real' things that differ between Al's car and a 'street' car are: no mufflers, no heater-A/C, no radio, no wipers and no legal tires (which I'm sure most fast guys here change to racing tires when they go to the track anyway too).
Not trying to get pissy.... just trying to say that these Stock Eliminator cars are a lot closer to street cars than you may know.

Y, Because I asked How a 346 LT1 ran 9's NA? I was not the one who said that stock headed cars are in the 9's, now did I? I wouldnt call Als car in the same class/catergory as ours. THAT WAS MY POINT!! If U want to believe deep down inside that they are, well thats just fine with me. Thanks
