Okay guys doing a swap for the 80 getting ready for some N2O passes but before going and chaning cams and installing the n2o i would like to make some NA passes on the 80, also i already got rid of the 102Fast and going to be running the victor JR just to see how much differnce it makes....



Best NA has been a 12.0 in 80+ degree weather this was with a billet 65 and the fast...how much slower do u think it will run with the 80 and a vic jr

note gears are still the same and stall is a little tighter now but still launghing over 4k

 

I'm curious to see what you run! Yeah the 4l80 Will slow you down, you have a converter for it?
And where did you pick it up?

 

I'm going to guess 12.25 at 107 mph with a 1.64 sixty...

 

running a 44 pi ill be going out on th 25th to make a couple of passes if truck is ready on motor and start spraing it with a little small shot like a 150 and work u from there
