Hello again. Been working on my carbs. 2 holley 600s Added metering blocks to the back. Went with 66 jets on front and 74 in back with no power valve. Problem is since they are inline wanted to use jet extentions in back but they wont let the float drop. Do they make a side hung float for use with jet extentions. Car 60fts in the 1.40s. Do I need them?

You don't really need jet extensions on those bowls, but they are never a bad thing. Not sure if they are even make floats for extensions with that bowl.

You absolutely need power valves in the front. From your post, I can't tell if you have a PV in the front but you need it. By the jet split, you are jetted like you have the PV's in the front.

So the carbs actually fit on the intake end to end with metering blocks on th secondaries??? Better for you if they do.
