And Pishta wants to compare a 170 horsepower 318 to a 210 horsepower 273 Commando thinking they are equal as the published numbers would suggest.
just because an engine can rev to 6K, does not mean it pulls to 6K.
.
it will if it uses the same cam as the heads were the same,and the valves are not so small as to choke it off which is not the case here.
"...The power ratings of the new LA-series 318 (1967) were exactly the same as those for the old polyspherical-head design, 230 hp and 340 lb-ft." Allpar
This jives with published 1967 273/4 hp figures...
1967 273 V8 4 barrel
Gross hp 235 @ 5,200
Torque 260 @ 4,000
If its published.....it must be true. :lol:
>>>>Disclaimer...all these figures are for a blueprinted motor. How many 67 318's has a 0.02 in the hole piston? How many 273/4 had a true 10.50 compression? I can tell you no 273 running today in this forum has a .010 embosses head gasket in it unless it has never been opened, likewise no 318 has a 4.00 bore head gasket as they as well as the embossed head gaskets are long gone. There was also never a 67 318 4bbl..imagine where that power level would have been compared to a like cammed 273. <<<<
