I found this info posted on a different site, its power curve is rather impressive for a 468 CID big block with 10:1 compression and a fairly mild cam
a .060 over 454 with AFR 265 heads,
with a 228/238 @ .050 hyd roller, 111/106 .549 lift,
10.1 compression,
Performer RPM air gap with a AED 950,
1 inch open spacer.
While the 630 HP at 6400 RPM is truly impressive,
if I'm reading the sheet right you're making
570 TQ at only 3800 RPM
At 900 rpm idle, 12-13" vacuum. I installed the AED 950 HO Modified as Mark ran it, just with the mixture screws and idle screws baselined ( primary set at square slots, secondary so the slots we right on the verge of being exposed). Engine fired up as soon as the carb filled with fuel, and sat and idled without holding the throttle, which I couldn't believe as it does not have a choke.
I had to close the secondary idle 1/4 turn to bring the idle from 950.
So I finally made it to the track Saturday. My new wheels are not in yet, so I had to run my 245/45-17 NT555R drag radials. I knew they wouldn't hook very well, but they were worse than I thought!! I also forgot to adjust the brake proportioning valve so I could do a proper burnout.
I'm running the engine as Mark dynoed it, except for no 1" spacer. Headers are 2" American racing, magnaflow 3" system with x pipe.
The track elevation is 1654 ft. Day was miserable, rain in the morning, then cold and windy. 8-20 mph headwind, temps 55 to 46 F.
My very first run with the car ever, actually my first run at a track ever! 12.891 @ 118.59, with a miserable .269 reaction, and a 2.55 60ft! Shifting the car at 6000, engine temps 155-160 all the way down the track.
My best run was my 4th, second round of bracket racing. Dialed a 12.42. Ran a 12.495 @ 118.99. .188 light, 2.273 60 ft.
ade it out to the track again yesterday, for the street car day. Needless to say there were numerous delays from fluid leaks, and more than one diff/driveshaft/u joint bit the dust! Funny thing was only one chev product, a new GTO leaked some antifreeze from the overflow on the track, every other car with issues was a FORD!!
Temps were 68F, and slight headwind of 2 mph. Track elevation 1650 ft.
I put my new Hoosier dot drag radials on, 245/45-17 size. I had to trim the fender lips by 1/4", as these are wider than the 245/45-17 Nitto NT555R I had before. The only other change was to inflate the front tires to their maximum, and put a switch in to turn the fan off.
I only put 3 runs in. My first run it rich bogged badly off the line, and I was manually shifting at 6000, which I then hit the rev limiter on each shift before the trans actually grabbed the next gear. So I decided to leave it in drive and let it shift on its own at 59-6000.
My 2nd run was my new best, 1.845 60', 11.779 @ 118.18.
The 3rd run started off good, but then half way through first gear it acted like it vapour locked? Sputtered suddenly and wouldn't gain rpm, then recovered?
Here are the time slips, left to right, left lane, right lane, left lane.
now your average nova with a tank of gas and a drivers going to weight in at about 3650 lbs
if we calculate a 20% drive train loss from the 630 flywheel hp we should have near 504 hp
throw the weight and trap speed in the calculator and it shows near 590hp so thats damn close considering we don,t know the gearing , tires or trans details nor the drivings skills or suspension mods
