Separate names with a comma.
Comp ratio works out to roughly 11.5. Can't divulge cam specs. Small AVS. 9" x 30 tire.
Holy shite! That's awesome!
You can't or won't divulge cam specs? That info is what the thread is about. Helping other guys get it done.
It's a stock eliminator car...
I wont. Not trying to be an azz but we spend a ton of money and dyno time testing cams for every few HP and really do not want to help another stock racer out. We have to keep stock lift, .462/.473, but can change the event timing and duration around. Typically duration @ .050 can be anywhere from 256 to 278. I use split duration on both the high comp and low comp engines. Low comp engines use more duration and different event timings. The piston to valve in the above deck high comp engines makes cam fitting a real challenge. Also helping these engines out are hydraulic valve trains that allow us to RPM these things over 7200. The transmissions are ultra trick and have custom gears to make use of the power bands we employ. Typical 60' for the high comp car is 1.32 to 1.34. The low comp car goes 1.37 to 1.39. For stockers 60' is everything.
bingo, most have no idea what it takes to make a stocker go fast. you're right, no ones business!!!! thanks
I didn't know it was that kind of car. And I understand keeping cam and other specs a secret. These kind of engine/cars have been listed here before under the hush hush rule. I do not pick up this kind of engine car build when it is posted and constantly get this answer which I pretty cool with. No doubt about it. We're good. Good luck in the races and thanks for posting. While most are not going to go this route, it still helps out.

Been a few years and a few more dollars since I first posted about my 318'd 72 Dart. It used to run 15.74, that was before the tired ol gal was torn apart, and given the rebuild it deserved. Block was boiled and de-burred, cylinder walls were just honed, crank was turned to remove grooves and high volume pump was installed. Keeping stock bore and stroke and adding a comp cams .454/.454 cam, 714 heads, 625 Street demon, keeping the Offenhauser intake and adding a 2000 stall converter. It now runs 14.52@93 MPH with the same 3.23 gears and 27 inch tires. Still haven't have her all the timing it wants and there is a nice set of slicks to be put on as well. Should be fun. Stay tuned.....
Wow! Awesome! Have any pictures of the ride and mill? Keep at it!
Here you go
OK I'll throw mine in here. Been a while and no longer have this car but I remember what I did. 68 Barracuda fastback. 360 balanced rotating assembly from Huhges engines 0.30 over hyper pistons with 10:1 compression.

just to rock the boat, and don`t get me wrong, I`m all mopar. ---- 1955 chevy, 265 plus .030, aftermarket 3 speed, oldsmobile rear end, 12" slicks, legal nhra superstocker, 11.39 when all is clicking right. not mine, belongs to one of my best friends, and my head man . 18 time national ex record holder. use to be neat to stand beside him when he dropped the hammer on it at 8400 to 9400----jfyi and a grins.
Thanks Bob but no thanks since this thread is to help the mopar guys with mopar builds. But still a good example.
this car rocks!
YEAH, but I like to let the guys know what fast is some times, SOMETHING FOR LITTLE ENGINE GUYS TO SHOOT FOR "
I’ll add one to the list.

That would have been in 90/91.
