Thanks, so reading this correctly the manifold and carb while might be not giving the performance should not be the problem
When I shorted out the entire passenger side bank leaving the car running on just 4 cylinders as compared to shorting out the drivers side there was a very noticeable difference, car would almost and would id say stall but keep running when I tried the other side
I read that as maybe whats going on with this engine.......Im busy today but I will do that compression check and a cylinder leak down if I find a low cylinder......Thanks again to you and everyone else

"Should not be" is correct. Even though small, the carburetor should run fine.....and from what you've said, IMO that's where the trouble lies. Not because it's a little small, but because there's an issue somewhere. Might have some trash in a jet or something.

Here's an old trick you can try. Get the engine up to temperature and with the choke open, run the engine up to about 3K and manually close the choke with your fingers a second or two, rinse and repeat. A lot of times that will suck some trash out of "wherever" it might be and clear it up. It doesn't work every time, but it's FREE and a lot of times it does work.
