I've seen A LOT of posts about making HP with a 318-So why is it so ???

One more......
I had a 9.7:1 360 with 230cfm J heads on it, small solid cam, LD340, headers, 750 Holley on the dyno.
It absolutely crushed the 8:1 360 with the SM heads and XE268 cam.

DD for this one has the TQ 17 too high, and the HP 36 too low, and peaking at a much lower rpm than it actually did.

It’s just not consistently accurate enough for me to put any faith in it.......which is why I don’t base any decisions for planning a build on it.
I am believing that the more I read. My stock 273 came out very close to the rated 235 horse. They probably used a stock 350 Chevy for a baseline and added from there. :lol:
