I have a 351c in my XY fairmont that I'm working on getting back on the road. I don't know the full details of the engine as it was built before I bought it. But it is a mild 351 clevo, with a high lift cam, and rather high compression.

I have just rebuilt the 750 vac sec Holley and got it going again. I noticed the jets were 72's while it was in pieces. I remember the previous owner saying he jetted it down for better economy before selling it. I know tiral and error is probably the best method for determining the optimum jet size for this engine, but can any one out there give me any ideas on what jets to try, or a range of sizes that I should be looking at?

Cheers

if you can let me know what model holley your running, ill let you know what size jets and power valves that came in it originally. the number is stamped on the air horn after the worn LIST or the letter L

Hrm the carby is now 160km away on the car, but its a 3310 from memory..
