With the recent TFS headed 390 build I was hoping to find what other 390 builds have accomplished.
The old FE forum had an updated 390 test.
"The engine is a +.030" 390 with stock crank, Scat rods, Icon flat top pistons, 10.0:1 cr, heads are un-ported C6AE-R with good valves, a good valve job and bowl blend. That's it. They have Harland Sharp rockers and shafts with their end stands, 3/8 Smith Brothers pushrods, Morel hyd. roller lifters and Straub cam. Basic performance oil mods to the block, Canton pan, nothing exotic.
Hydro Roller cam: 237/243 @ 0.050" 108 LSA 104 ICL 0.641 intake 0.621 exh lift."
results 520 hp @ 6400 rpm and 473 ft lbs torque at peak. Very impressive for old Ford iron heads!!!! Dual carb intake seems to work very well. These are corrected numbers. I did not see uncorrected numbers.
Just showing that old iron (heads) isn't as bad as we seem to think.
