Hello, I am attempting to complete this rebuild for the engine in my 72 C10 the eng is 350+30, performer intake,202 heads,224/230/110 cam. I know I need the idle tubes,secondary jets, rods and hanger and the rebuild kit. The jets that were in it were 74s. If I should use a different size include them. I think I should use new rods here also. I am not sure whats in the kit as far as screws and springs.
Some of the measurements are: Idle down channel .051
Upper idle air bleed .046
Lower idle air bleed .076
Main air bleed in air horn .086
Mixture screw holes .0625
Thanks for the help.
