Hello

I have a 2276cc motor with FK46 and CB 1.4:1 rocker arms. The heads are CB ultrawedgeport 46x38 and the carbs are 51.5IDA with 46 vents. CR is 11:1.
The manifold are big beef ported with the heads by CB. The track is at 1500meters above the sea.
The gearbox 3.55/2.21/1.58/1.21 - 3.875 with a quaife inside.
I would like to have a ballpark for the jetting ?
The goal is to achieve a mid to high eleven. The car is a 64 bug.

i have also a FK89 but i put the FK46 this time.

Thanks for your answers and feel free to tell me if something is wrong in my combo.

I recently had my 2332 cc on the Dynojet, IDA's with 44 Raptor venturies, MS230 heads 48 x 38, Raptor cam (similar to FK47), 1100 metres elevation.

I ended up with this jetting:

F2
180 main
210 air
65-120 idle

Combo looks good for a hard running street car.
11s are possible with this combo if the car is light enough and on slicks.
If it is going to be just a racecar then more compression-13:1
