110lsa is definitely risking reversion on wet exhaust.

There you go. Side by side.

To me that 110 lobe center starts getting interesting because even though the Comp cam appears smaller its actually a rougher idle with a mid range power band .

Normally aspirated as I stated low idle reversion could be and issue. It is super charged now and that will change the reversion pulses at idle (Low Low idle are still a issue)

I think it will be Fine but you may want to check back in with Mild Thunder whom your original set up was with and confirm. He's been down this road with his experience.

Engine warranty ?? Just curious

Not sure about the cam "he picked" but feel you would have a high likely hood with the 134561. I used that cam in a 454 after it being recommended by a very well know person in the industry. It was to much for the exhaust I had and I did have a reversion issue.

Is he paid in full? If not hold a $1000 in a escrow, if you have no reversion and makes 600+ hp you release the money.

How about telling us who it is so no one else has to go down the same path?
