371 build W/Big Mouth heads

Be curious to see what that motor makes with those butchered heads.
We just modified/ rebuilt a 30 over 360 and are very happy with results thus far.
Has eddies that were ported in an evening moderately, bigger flat tappet than this motor260/264@50, that is probably too big, but was on the shelf and wanted to get it running.
Airgap that is untouched, 950 carb, dinky 1 5/8 headers, 727, and a mismatched 4500 convertor
Car weighs 3300 and has been 117 mph thus far shifting it at exactly 6 grand. Crosses at about 6150. Bone stock shortblock, heads milled and thin gasket to achieve 10.5 compression
Not sure what 117@ 3300 is but its gotta be 500ish horse, and with a 904 and correct convertor i think it will run 119-120 pretty easily.
This build in this thread should make 550-575 even with the small cam, but those heads are mighty suspect.


117@3300 is about 425-450 HP.
