My mistress needed some engine compartment height so I through bolted an aluminum I beam around each hatch and re hinged the top. I put electric actuators on them to open close.

You can see the I beam in the picture if you look the engine. I needed that with the Flame arrestors and when I thought I was going to run carb spacers.

Yes, I believe Texas. It went to LOTO from me originally. And got lots of use, I believe 600 hrs. And then was sold to a guy in texas, he is a member of offshoreonly, I can't quite remember his screen name.....maybe he will chime in

When I sold that boat the economy was failing and I had a Top Gun I wanted to buy. That was a fantastic deal when I sold it. The guy in LOTO like I said ran the piss out of it. Konrads and 700s. Just changed the oil and it went. For the price that it cost to get a mistress to that level, it was a steal.

I am a few weeks away from my 540's being finished. similar to Tim, Bob M. spec the cams and heads. afr 325 114 cc the cams are 242.2 664 on intake 247.1 656 on exhaust flat top JE pistons, merlin 3 blocks zero deck and the head gasket he set me up with from cometic is .027. I am running Nickerson 4150 on merlin single plane intakes. carbs flow 994 CFM. as soon as the engines are complete they are going to Nickerson for dyno and tune. I will be happy to provide the results here. I can find out from my builder what the final comp. ended up, our target was 9.8 :1. will post more info as I get it.
