Does anyone no the h.p. ratings for the d3ve 460 engines and valve sizes,and head chambers thanks.

 

According to this source book, the 1973 460 engine had a horsepower rating of 219 net@4,400 rpm.Compression ratio listed as 8.0:1,91.4cc heads,2.084" diameter intake valves,and 1.653" diameter exhaust valves.Curiously,it doesn't list any engine torque ratings in this specific book,but if I remember correctly, I saw a torque rating for the '70s era 460 engine that was 357 lb./ft.@2,400-2,600 rpm.

 

Thanks for the info.,bro on the 70's 460 i had read something close to that and was hoping it was correct.,hoping to get about 300h.p. out of it with change of intake,headers,camshaft,and better carb. thanks.
