I thought about picking up the Griffin at that price, but I do not need it currently, and decided to hold off since I'm focusing on the valvetrain this winter.



It doesn't matter how many times we repeat ourselves.... Some people never want to learn
Going for more horsepower and revs than torque?

2.4 or 2.0? Off nitrous I've never seen a sc'd ecotec make almost peak Trq at 2200 rpm.

From my own experience, fuel and timing play a huge role in how smooth your graph ends up looking. How well your head/cams flow plays a big role too; but that's just icing on the cake.

Something very peculiar about your graph to say the least.

Yes sir!

The S1 cams will still provide a fairly decent torque curve, but the extra power up top should be nice.

This.

Almost looks like an LNF graph....

The horsepower peak too early as well.

Poor injectors. There should be a law against beating 60's that hard.

Even if the links worked, Tim's car should be in the le5 section.

I wouldn't be so sure. Depends on the place you get your e from. Find a "blend at the pump" station if you can.
Stations where it comes already blended can legally use "any hydrocarbon in the same flash (flammability) range as gasoline. Which means they can use the leftover junk gas as the 30%
Blend-at-pump stations mix it right there with 87.

Quality e70 "should" still be able to give you nearly max power depending how hard you push the tune.

Not to mention the graph does not show an LSJ's powerband....

That's def an LNF's graph. Unless the tune or dyno is that screwed up....
