...The 'Torquer' single plane, I use to run, can have a fuel distribution problem, concerning cylinder #8. Also idles more rough.

On the street, Idling at a red light, the driver behind you, will be severely tearing-up.

My opinion...take the jets out of the 600, Install them on the 750 and you'll be Dead-On.

Thank you MJ!
The motor currently has an aluminum dual plane that looks similar to the edelbrock performer but with no logo in the casting. I was hoping to the single plane would yield some more top end. The cylinder 8 fueling problems you experienced sound concerning, is this a common issue with the Torker?
I guess I will be buying a jet kit to avoid committing chemical warfare against drivers behind me
