Update: So started the engine this week ran Great, didn't have my rev limited set right ran the motor up to 6400 rpm, got that fix set it at 5500 so all good now. O2 sensors seem to be staying dry and no problems so far. Do have a video but not sure how to upload it, Holley Sniper is working as it should still need to do final tune but started 1st time.

Will be on the water Saturday and hope to down load the logs after a test run then get with Alex to final tune the rest. It ran really well and with Eddie Young extending the inner pipe I think all is good, didn't go with a big cam, but still made 586hp.

Nice setup there!
We've run them in several builds (cars), they work great, only had one issue with one of them and it was the screen was glitching on us, but holley has a good warranty, they replaced the handheld with no problems...with a marine setup i would say the only concern is keeping that 02 dry, otherwise your good.

Dyno'd my engine yesterday afternoon very happy with it
They broke it in prior to me heading down
We made a couple pulls, ran very well
Did not have time (small mom and pops shop and had three engines lined up to dyno) to do comparisons with carburetor, should be able to do that on the next one this winter when he slows down
668 ft/lbs at 3600
616 hp at 5500
incredibly flat torque curve 640ft/lbs at 2700
ran on 100 octane
454 -60 over, 188 heads, Howards roller cam, 8.5 static comp
177 blower with 3" pulley on top and 7" on the bottom
Teague chillers too
Single Holley Sniper
Dyno headers with magnaflow mufflers
I'll probably de tune it a bit for installation
Sniper worked excellent, the digital dash is an awesome tool
I'm looking forward to next summer!

Well weather was not great last weekend but tomorrow it goes in the water for a test run, will take some video and data log the results. I did run it for about 30 min on the muffs no problems.
PS: almost 70 today in Texas, 65 on Saturday.......
