I do a warm up on the trailer at home so I can just drop and go. Very busy ramp with no dock.

Same here. Always nice to drop and roll and with no surprises. I've seen a lot of some pretty messed up chit go on at ramps. Shovel fights, golf clubs, you name it. Years ago I'd get into it now I just crack another beer.

Overall visual check and a couple times a season the timing light comes out for a quick check (how I found out my old MSD distributor was corroded beyond belief )
I like to dunk and go!
It is quite a bit of fun to watch a public boat launch on a busy day. (Especially jet ski owners)

A lot of myths with aluminum heads... we did a swap in the past but tested by MPH and ET... engine was in car. Everything being fairly equal we actually ran the same MPH but a bit better ET... long story short the engine did take another 2 degrees of timing until MPH flattened out. Result was 2mph and .15. Was on a 10.50's car. So this shows the weight savings was worth more than the power. We feel overall it's making about same amount of power but took another 2 degrees timing to get there.
