Manual Valve Body Standard Shift

Aaah yes we run a 7.50 index class with a 6.90 car . Soo we have to slow the car down , a lot of people retard timing ,use a throttle stop ,richen the jets, etc. We use a restrictor plate with interchangable venturi which vary in sizes from 1.300 1.200 1.100 and 1.000. Previously we ran 1.200 to make the car run 7.50 in the 1/8th mile when we changed the valve body with the 1.200 it ran 7.28 in the 1/8th. We ended up putting 1.000 to make the car run 7.50 in the 1/8th. This also picked up the 60ft time from 1.59 to 1.56.

We have had traction issues but hope that we now have them ironed out. Maybe we can make a wide open pass soon to see what the car will actually do.
