Rejetting QFT 950 meth to gas.

[marian212]

Hallo,

I have 440 stroker with carburator quick fuel 950 cfm orignially for E85 and runs on meth now. I need to convert to gas, but can You please let me know from which jets and power valve I should start re-jetting ? Currently I have jets 85 and 92 and power valve 3,5.

Thanks for any suggestions.
M.

Are the metering blocks Green?....If so you will probably need to swap them out also as the internal passages are enlarged for the e85

I would call QFT to see what they say
