What do you mean by "built too much"???
Is it a driveability issue??? Soft low-end throttle response?
What's been done to the mech. ignition curve??
What carb and carb tuning so far??
Typically many guys bolt on a carb and drop in the distributor, set total advance, and then the dissappointment begins when they want to street drive it.

Thing is the gas cost as I was running 100% 110 with lead for one high compression and 2 no problems with storage getting lines and carbs messed up from bad gas So wondering how low I can go with octane etc... Dist was set so it starts up fine and runs well that's all I know at this point. I know I have to do a few things to get the kinks out as they never were addressed Small oil leak at pan conner, One water pump bolt leaks antifreeze and needs sealant Intake I think is sucking oil in from galley and needs pulled and milled and reinstalled as it sat to high on the commando heads I never fooled with it as I had to rebuild a whole home ND THEN OTHER THINGS CAME UP SO CAR SAT. would like to address those issiues and drive it if gas is not a large cost

Got E-85 ?
If you can get it then run it. You can have your carbs re-worked for it or buy a single 4 set up for it or do what I do and just use it like pump gas with NO CHANGES. I have done it for years and never had any problems. It is much less picky than gasoline about the fuel curve, it does like more timing though for sure.

there's at least three things you could change to de-tune it, but i'd want to know the cranking compression on it before i suggested anything. it sounds like you want to run pump gas, right?

let me ask again if you don't mind; what is your current cranking compression?
have not checked and tools are not here for doing that at my home right now. Things are moving fast on my health issues, so looks like more test and meets with docs next week minor surgery. And Chemo soon after that so will just let the car sit more till that's over with. Was thinking i had time to pull it down mill the intake fix a few things install full exhaust and use it some first. Thanks for the responces
