benchmark jetting 4 x 48IDF on 302w

[Ron Grundy]

Hi all
I am brand new to any types of forums, so I hope what I am doing makes sense??

I am about to replace the holley carb on my gt40 with 4 x 48IDF carbs, and I was looking for a baseline jetting guide for all 48idf variable internals.

The GT40 is street driven only (hence the IDF`s) and is a mildly modified ford 302 windsor, original cast heads, engine has been cleaned up with reasonable hydraulic camshaft, 5 spd. renault transaxle with 3.88 final drive and will use 98oct. unleaded fuel. I would like the car to be sharp but very drivable.

The original components on the brand new IDF`s are : 40mm.chokes, 4.5aux, 150mains, 180air corr, F2emmulsions, 55idle, .200n/seats, .50pump jets

Any tried and tested combinations would be greatly appreciated

Best Regards Ron

 

I have a simular set-up in my Cobra Fia,Here's the specs I'm running ,seems to run pretty well.37mm chokes,Idle Jet 60,F2 Emulsion Tube,Main Jet 155,Air Cor.200,Accel Pump Valve 55,Pump Jet 50. Hope this helps.

I've got some for a 347, X303 cam, good AFR heads. Once I dig them out I'll post them.

I'll look through my info this evening for sure. I had a build sheet on the carbs and it has all the specs.
