Decent gains, useually Ported Fast 90/90 does that alone, or close to it, has the car been retuned? Or working on the old SD tune.

It was retuned. I Have run both of these cams. The 228cam on 112lsa peak torque is about 400 rpm sooner. They are within 5hp of each other.

I'd be happy with 11.6-11.70's. I have a GTO event at Atco NJ Oct 28. Thanks

Matter's if the car needs a ported 90mm. I've seen cars lose hp with them.Rarely happens but does happen.

Too bad the new Cam didn't fit.Hopefully this winter the pistons will get cut.

It's called letting off the gas.

Don...

Cut Vettenuts some slack....if you let off the gas why would you get back in it for a few hundred RPM.

I was thinking valve control issues as well to be honest with you.

Nice results by the way....I especially like the TQ gain.

Regards,
Tony

My new ported fast from XXX Motorsport will be on next week. I`m wondering what I`m going to make power wise from my LME ported 90! Will know next week!

I have the old man flinch sometimes when trying to watch 3-4 gauges at once,

After that run I backed it up to 6900rpm which had no dip.

I'm just playin with Vettenut's, he know's I love him

nice gains, you'll have no probs hitting mid 11's and maybe a bit better. I like when people post dyno comparisons, it really helps to justify a particular mod and not jsut taking peoples's word on them.

I wouldnt port the 90TB,I have seen some idle issues with them along with power loss.I beleive this other cam was worth maybe 5RW like I said on GTO tech and the intake was worth at least 20RW....Pretty good gain,and like Mamo said the TQ looks great,I love the FAST but its just too much money for me,I'm porting my LS2 myself and hope to net 5 to 7RW out of it.....

Your setup is impressive

Thanks, I can really feel a SOTP difference with these mods. I'm still amazed by this little 346ci motor. Feels like my old 462ci big block Monte Carlo.

Just to be clear.. Were these gains going from stock LS1 intake, LS6 intake, or unported FAST to the Mamo ported FAST?

It's not clear what you started with. Thanks.
