quadrajet gurus.....need help
Are the power pistons from 4MV's interchangeable with other 4MV's? My carb # is 7043507 if needed. Thank You in advance.

Re: quadrajet gurus.....need help
They should be the same for all MV series carbs, The difference is the piston spring tension and of course metering rod size per the application.

Re: quadrajet gurus.....need help
I would think so because I changed the power valve in my 4MV to one from a M4MC without any issues
