48 IDF jetting.
Hi.
There are currently lot's of posts on the 48 IDA jetting, but few on the IDF. The first question is then: will the "ultimate" jettings for the IDA also apply to the IDF?
I'm running a 347 stroker and will reach 8000 rpm. According to the charts, the main venturi in my IDF's should be around 45 mm+ for max power. This is not happening.
Is the 37mm main venturi the way to go (driveability + top end power) or should it be let out to 41 + mm?
What's bugging me right now is that the jetting chart for my carbs have gone missing (I was SURE I saved a copy in this computer..).I'll have to look through my books and find it!
Regards
Rune
