Got my freshened engine on the dyno.1st time fuel was in the carbs.2 squirts and at the hit of the key it came to life and sounded great.When the dyno operator went to throttle up,it would not come off idle.After manually getting off idle,the dyno operator felt he had inproper control of the throttle.The concenses in the house was that the 11 inches of vacume under the carbs kept the dyno throttle from being able to open the carbs off idle.Ant similar experiances???

I have readings from the carb spacer & intake manifold.Both are 11 inches at idle.

i dont see a problem unless the blades are sticking in the carbs.do thay move freely when the engine is not running and just using your hand on the carb lever?

 

[blownzoom440]

by the way did you get some pulls done?results?

 

[jstahemi]

Yup,2 squirts and it lit at the hit. 4lbs,8lbs & 10 lbs resulting in making me very happy
Next week I will order a new converter

How'd those SV1's work out? Got some PSI'S I might try some on. Anyone have opinions? Thanks Bob

I've got a pair on my blown Pontiac. They've worked very well for me.

They were not used for the dyno session because the dyno throttle could not control the throttle comfortably.I was very lucky to have Steve Gill lend me his 2 Pro Systems dominators.rayer:rayer:

We have dynoed with them,sounds like you just had a throttle geomtry problem.We have a full drawer of linkage .Its amazing what it takes to get one to work sometimes.You get your a/f right you will see that torque change a bunch

Thanks Vinny for your reply!

Thanks Vinny for your reply!

I dont know your full combo but normally 11.6 to 11.9 afr at peak torque and 12.0 to 12.3 at peak hp works well.You are a bit lean .imo.

 

[Vinny V]

Thanks Vinny for your reply!

And on some combos 12.0 is getting lean.You get to the race track and get some mph involved you will be dangerously lean .Some engines wont hardly dyno at numbers i stated but the racetrack at speed >whole different deal.Sounds like your excited about outcome /have fun.
