i am looking for a 13b mainly bridgeported NA dynosheet, if anyone has one please post...

the search didnt do anythign for me

 

I'll have a good dynosheet of my 12a J-bridge carb n/a next month.

I do have a dynosheet of same motor with it running rich 6-7k and real lean above 7k, won't do u much good....

 

Brad :I`am happy to see i`am not the only one running a J-bridge!

For interest`s sake :How did you go about running it in ?

 

This is for my 81 7 racecar so it's needs and noise level are a little different from a street motor. Not registered so I can't drive on street! Anyways:

Idled motor in neutral 1hr
Jacked up rear and ran the motor in 4th gear for 2 more hours.

Then Chassis Dyno breakin in 3rd gear:
40 min @ 4000
40 min @ 4500
40 min @ 5000
40 min @ 5400 (couldn't get it up another 100rm)

Then Several shots up to 9600rpm for fun and power run/tuning.

Memorial weekend it's going to the track for drivers school. Saturday max rpm 7000. Sunday max rpm 8000.

Then back on dyno and fix lean and rich condition and she'll be ready for 9600rpm!
