Out of a total of six runs only three was worth talking about. 13.62 @104.24 13.45@ 104.94 and my last at 13.02@105.26 All was run on255-60-r15 so I had no traction I rolled out of first real slow and floored in second still spinning and shifting at about 5800 did not bring the motor up to 6400 were I was told to shift. My reaction times were in the1.01rang but I didn't care so her it is also could someone Give me a guess were my time could be with good traction Thanks jethro81z-28

1.94-----60
5.41-----330
8.35-----1/8
83.77----1/8
10.89----1000
13.02----1/4
105.26---1/4

Wow, you got six runs in!!! I'm lucky if I get three. :rolleyes: I think you could easily shave 2 tenths off your 60ft. And with 105mph trap speed and shifting when you did, I'd say mid 12's...easy.

Also, I wouldn't shift at 6400rpm either...at least not with a 6200rpm chip in the rev limiter. Just kidding. graemlins/thumbsup.gif

I bought the pack 6000 to 7000 but mid 12s sounds good to me.

Mike,
I had a great time hanging with you guys last night. That 13 flat is a very good time for your first time out w/ your new motor. I think you're motor is "on the money". You'll be in the 12's just by dropping your tire pressure and getting familiar w/ shift points and launching. You could also spray some VHT on your tires to help w/ the launch. Trap speed, not ET, is the best indicator of HP and your trap speed was very good. I looked at the BFG radial TA's on my '67 and I think they'bolt up on the '79. They're 265 50 R15. The wheels have a 7 in offset, which may be a problem. Maybe at least I can hook up enough so I'll need my helmet graemlins/clonk.gif

Thanks guys In about three to four weeks I`ll be back with a set of D.O.T.looking for traction and mid-12s. I`ll be glad just to say I have a 12 sec. car but any way total timing is set at 36* and all in by 2800. Holley 800DP Front jets our 72 and back 76, car seemed to run stong whin I got traction so I hope some good rubber will help.
So Mike be ready and lets go play.

With good traction 12.6 - 12.7's are doable with 105 MPH. You'll need to get your 60' times down into the 1.7x range though . . . isn't lack of traction a fun problem to have :D

jethro i run nearly the same engine combo except for cam its in a 67 nova and runs 7.os to 7.teens depending on weather in the 1/8 mile and is a little lighter i know but here is a starting point for you to try .you know though that every combo is a little different 74 /81 jets shift at at 6gran to 6200 reving them higher dont make them run faster always .i shift at 6400 with mine now with the roller . when i ran a solid i shifted at 6 to 6200 no sense pushing the motor if the results arent any better . now get that thing to hook and you might be suprised at what you run

Thanks guys for input all the help is appreciated Thanks Eric68 for the advice you gave me 6 months ago on the build up of this motor
