Thanks for help and one more question

I thank you guys for the fast help.
I couldnīt imagine that there are so many parts to consider.
After your helpful opinions i think youīre right and itīs the best decision to look for an other carburetor.
I really prefere the Autolite 1.08, but if i donīt find one, is there any other carburetor you can recommend?

For example Holley.... which model is the best for street use with power at low RPM?

I donīt think that an Edelbrock is the right choice.....

Do you prefere 4bbl or 2bbl?
There are a lot of different opinions about that and iīm far from expert!
Some say that a 2bbl (for example the Holley 2300 500cfm) has more power at low RPM instead the 4bbl....
What do you think about this?
