Similar but not the same, as you know.

So while the lobes look very similar to a 5 year old lobe carried by somebody else, it's doesn't necessarily mean they're the same. But like I said Ed, you know this. But not everybody else on the board knows this.

Within the specs noted, I'd bet there would be minimal delta in power one way or the other between these lobes and the ESP lobes, if used with the identical timing events and application. There just isn't enough QC in manufacturing to get them to split the lobe specs "that" perfectly. At least from what my Cam Pro shows.
No matter, it's good to know Geoff is going in this direction. Makes me think it was worth all the expense on our end too! Especially since you guys are seeing great results.

Mike emailed me back and told me cars coming from other SAE dynos are very close with his STD dyno.
And as far as injector duty cycle, they were maxed out, but it could be the fuel pressure dropping. I would need to install a fuel pressure gauge and see what the pressure does on a long 4th gear pull. If the pressure drops, it is the fuel pump or delivery related. If it holds steady in the 55-60 PSI area, it is the injectors.

After reading this thread I feel disapointed in the power my H/C combo is making. My cam is very similar in duration, different lobes, and lsa. Wondering if I did a swap, would this cam produce more power? I have a Futral F6 226/230 .575/.595 with TEA stage 1 241 heads, the heads are milled 0.030, and I run 0.040 cometic gaskets.

Different day, motor, weather, dyno..... Not all H/C cars are going to have 440+ hp. Hell I have a pat g cam in my car and I only make 386/360. Could be a low reading dyno, gears robbing power or some shitty air quality. But my car runs its *** off! I would be into the 11s if I had a 9" or 12-bolt.

I was looking at EPS cams. I wanted something smaller like 222/226 to stay in negative overlap territory. On EPS website it is offered on a 113. What LSA and advance/retard would work best? Probably going to match it up with LS6 heads(should I get them milled?). Already have LS6 intake and going to get LTs before cam. Just need help picking the right valve events.
