whats the ideal weber set up?
 

Guys i have a euro 76s 2.7 with cis , i am ripping off the cis and going webers (i hope) what is the best set up i;e
- 40's or 44's
- what jetting would you recommend
- any additional information that would help?

I'd skip the Webers and go with 40mm PMO's.

40's with 34 vents is perfect for me

are you running std cams the compression (cis set up on carbs?)

40 Zeniths would be cheaper......

a 2.7 per rpm needs a fixed amount of airflow that 34 vents satisfy

i am using e-cams and 8.5:1 pistons

There are some great posts in the engine rebuilding forum of guys going through this exactly and a lot of advice from others. You should check them out. If I was on my computer instead of my iPad this evening I would send you some links.

Carbs will work great on this engine. I'd use any of the set-ups you find on here to start with. You really will want to dyno for fine tuning, or buy a wide band O2 meter. I have a cheap WB O2 meter in my car and it is a Godsend for tuning.

I'll second that. I put a AEM wideband analog gauge in my racecar and it's a great tool for tuning and monitoring fuel delivery behavior. It pays for itself very quickly. It's like having your own dyno at home before you take it to the dyno.
