  5. Well fellas, I was so anxious about this whole mess, I about fell over after the first run was made. Turns out, I don't have to light it on fire.

    The below graph is from run #3 of 4 total. First pull, right after driving the car there, it did 333 and some change. Second pull we added timing (from 14 base to 16), and it went 334.X, but went as lean as 14.0X around 6200. Third pull I added 5% fuel, and it did 336, as seen below. AFR on that pull was around 13.6high. So I added another 4% and we did a 4th pull with hardly any cooldown time and it came back down to 333ish, but AFR was at a more comfortable 13.low.

    I'd like to point out that it made over 300 HP starting at about 4900 (where I have the data line set to, below) and just carried out until the dyno operator cut it off at about 63-6400 RPM on every pull.

    So I'm beginning to think the car weighs more than I think it does, judging by my dragstrip trap speed, LOL. Time to go on a diet. (And learn how to drive.)

  6. That is phenominal, bro! Just about the best looking street 302 I've seen. Your theory paid off, and hopefully paves the way for future combos.

    I'm ****in' stoked! You built a monster. Makes me happy I went 205cc on my 331 instead of chickening out on 185s. I'm sorry I ever wasted time on AFR165s on my old 302. Just keep datalogging on the street and at the track. You might find that the AFR changes a bit while the car is actually moving and under real load. Chances are you've made a noticeable improvement.

    I hereby renounce my incorrect estimation and revert back to the one I made when I knew more about foxes ;) :

  7. That's pretty impressive man. Do you recall what your heads flowed? Congrads! Can't wait to see those things on a 351 based motor.

  8. Did you go through the build thread, joe? I think it's buried in there somewhere. I seem to recall Nik giving up the numbers at some point.
     
  9. Thanks man! That's funny that you had predicted so close before... Were you starting to lose faith? :)
     
  10. I think they were around 320ish @ .6", but that info is all in this thread somewhere...
     
  11. Lol. Yeah, I read the build thread, but it was about 2 years ago.

  12. Um... I guess so. I think the new guess was based solely off of your trap speed, but I expect that'll be coming up pretty nicely. I would be interested to know what the car weighs. Seems like you ought to be going 113-115 mph through the traps. I think those 3.73s should be fine to get you out of the hole and giving you room for more in the future.
     
  13. Congrats!! Now go get some more seat-time and show us some nice ETs to match that dyno sheet. :nice:
     
  14. That's awesome Nik! Congrats!!
     
  15. I've seen 347 combos on youtube lay down less HP than that. Great numbers!
     
  16. Very impressive, indeed. I'm glad I was way off, hahah.
     
  17. time for real gears (4.10-4.56) and traction. I think it could trap 114-115mph with a few simple things.
     
  18. Video! I'm the goober in the shorts by the antique computer monitor.

     
  19. Man, you crazy. I'm perfectly happy with my 3.73s. It already makes too much noise at highway speeds haha.

    I have been toying with the idea of putting the car on a bit of a diet by ditching the 28 lb Mach 1 wheels for some Billet Specialties Street Lites (still 17s to clear the brakes), maybe a tubular K-member and A-arms, and then maybe some long tube headers and 3" exhaust all the way back. That would put the 351 build on hold for another year, but it would be kind of fun to see how fast I can get this 302 to go. Plus, with a new exhaust setup, a switch to 1.7 rocker arms, and maybe a box upper intake, I think I could crack 350 @ the tire, which would be pretty awesome.
