Thunderbolt IV V-6 Module
Would installing a V-6 module help with low rpm running issues?
I have a 30 over Mark IV with AFR 305 cyl. heads, Edelbrock Victor Jr intake, Gil wet exhaust, Holley 850 and my cam is
231/235 @050
578/618 lift
112 LS
Base timing set to 10 deg.
Idle vacuum is 5ish and bouncy
I changed the power valve to a 2.5 from a 6.5 and that helped.
Once out on the water the boat runs great.
Thanks

I had an issue with a SBC I was working on. The idle was all over the place and I was chasing my tail. An old school hot rod guy said plug up the breather openings, one with your hand. I revved up the engine and could feel my hand suck in. It was a slipped intake gasket by a previous owner. I now use Gasgasinch to glue the gasket to the intake before installation. I've not had a leak since.
