Do you have the cam card?

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?

See, and my blower motor has .566/.566 218/218 114*

How would you explain?

Its an OEM LS9 cam

Full LS9 cam specs:

.004 duration 277/295

.050 duration 211/230

lift .562/.558

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.

Its funny that we're so similar with our taste in cars, but we argue so much. Hah

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.
