1987 Ford F-250 460ci spark plug gap?

[some guy s]

Hi, we just bought a 1987 Ford F-250 XLT Lariat 4X4 extended cab 8 foot bed. it has a Holley 650 carbureted 460 engine with a 10.5:1 compression ratio, an RV cam, and flowmaster exhaust.

does anybody think they know what the spark plug gap would be on this truck? i know it's far from stock, but i can't even find the stock spark plug gap on google. let alone this configuration. it's got a few tweaks but overall in good shape. any help would be very much appreciated!

.042-.046 stock hotter cam go .046-.050 and make sure ignition is in good shape. preferrably aftermarket coil at least or ign box set up.

I agree with Martinmm, the spark plugs (gap) should be set at 0.044.
