Ditto. Those seem like some odd specs.

What is your LSA? 122.5 center line is probably for the intake...still a little weird....who makes the cam and what part number is it?

Youve got way more lift and way less duration than me. And I have a roller cam.
Im 239/ 245 at .05 and 520/540?

Burden of proof is on you not me. I said SBCs were different than LS1s. I dont care about SBFs, not relevant. Theres an example in front of you, explain the variance.

I explained the "possible" variance, why would a 40 year old ford motor be so similar to a current tech chevy motor? Engine stuff, not brand stuff.

What was your argument again? I don't even have to look at the actual specs, part number of the cam is enough to know its close. 280 series grind on a SBC is the same as a 280 series grind on an LS which is the same as a 280 series on a sbf. For comparitive purposes both are OE hydraulic roller.
Since buying a shelf cam is RETARDED and custom grind is always the way to go, there's no argument to why what is what. These profiles were designed nearly 30 years ago.
