Which intake to run, I have two intakes, vic jr. or holley strip dom.
406 chevy 10.2.1 comp. scat 6'' i beam rods, brodix 210 runner heads, sm solid roller 244-255 577-600 110lc 750hp carb, 1''3/4 headers, 68 nova 3400lbs 5sp 3.73 gears, street strip car. what intake would work best with this combo? Thanx Darren

A 5 speed means it has a ton of low gear with the 3.73 the motor is not going to wind up real high the air gap will pull to 6500 and you have no stall to cheat the single plane up with, I might trim the divider on it. Hey its my choice for what you have with a good 4150 on top.

The Victor Jr. can be a very good intake with some porting help. Here is one I did for a Friends 406

Factor that in with how many guys have manual trans in their street strip car, and need to accelerate without a conveters help on the street, unless your going to clutch it and down shift all the time. Try what you have its a easy swap, if you happy run it.
