Beautiful boat UD, very impressive. Thanks for posting!!
Cam is Engel GHR-236/242 on 110 lobe centers (vs standard 114)
Its advanced a bit - I think 4 degrees.
Some of the younger builders like Bob Madera and Alexi seem to have even sweeter combos that make even more HP, but I don't know if id get 10 years out of them or what more I would have paid upfront.
Dick was a treasure trove of info but was as hard headed as a mule and rightfully so.
Uncle Dave
I have a pretty decent piece in my chevelle, car not boat so its a totally different world. True street car though, easy to drive and no need to pull timing or any tricks to get it to go around town. Drive over 50 miles each way to the track at 4k with the gears and am good to go.
Chevy 400 block
splayed (sp) mains and girdle
421 CID
6.2" rods
JE pistons @ 10:1
Heads: World Products sportsman II's 200cc runner, 72cc chamber (all when stock)
now has 2.05" intake and 1.64" exhaust
Bowl work and some other "stuff"
cam: solid roller
lift: 601/625 and then a 1.6 rocker on that
duration: 258/262 @ 50
lobe centers: 108 degress if memory serves me correctly
Hoping to have some dyno numbers in the winter for it finally, getting ready to run True Street in the NMCA for the experience.
Whats your estimate on what its going to make ?
UD
That would be a cool trick. 5-7% more power with only 750 rpm AND less peak torque.
When I get time I will write WHY UD's back is already pretty much up against the wall. Let me just start by saying that Dick Gazan(RIP) was no slouch when it came to spinning wrenches and he was a pump gas guru.
Guessing HP is a dangerous game where everyone will want to take a shot at you, but I am hoping for something in your neighborhood. It will be on a chassis dyno so we should know both ways. Pretty sure all the results are going to do is make me want some AFR's for it and kick the compression up since the aluminum head will be more forgiving obviously. Either way, if I build anything again, it will be LS based. Too much cool stuff and big numbers with very streetable personalities out there to not make the switch over.
GN7, I will stick with my guess... I'm assuming Uncle Daves CR isnt more than 11:1 if he is getting by on pump premium... Uncle have has a decent spec. hydraulic roller and Chevelle has a nice smallish solid roller...
5% more HP would be 25 +/- and Daves cam/heads/carb set up is done by 5600RPM...
I wager that Chevelles cam/heads are done by maybe 6300RPM +/- 100 RPM for his peak HP... With the same or maybe less torque...
Uncle Daves combo makes 510 TQ at 4400RPM :)
Hope all is well my friend...
NOTE, Chevelle: I don't mean "smallish" in a bad way at all and I would prolly pick something with the same manners if I was going to drop the $$$ for a solid roller...
Good stuff here.
Dicks mills are just a little less durable than an anvil.
I regret not meeting Dick sooner or I wouldn't have wasted money on building and re-building blown small block variants.
I never could get that shit working right, and when Dick looked at it the first time he started laughing at me.
I wish Id have had him build me a big block, but I can put ridiculous number of guys on the trailer with this setup, and its such a bargain I hate go mess with it further. The boat though can take more speed and still be stable.
This little boat has actually had a lot of press as it was the Laveys flagship Sebring for a few years before they sold it off to me.
Heres a trip down memory lane- check out Bob Nordskogs face while test driving her in 91 performance boat evaluations.

Uncle, you know I think your set up is right on...
I certainly didn't mean to come across like I was trying to give advice or say anything negative about you OR CHevelle's build...
Clearly you have to balance having something with manners, a reliable piece AND squeezing every last pony out of a mill with regard to compression ratio, running a monster solid roller cam AND/OR twin dominators... :)
Lets plan on making a trip to meet ole Joe in the near future... Just for kicks... http://www.joeshermanracing.com/
Wasn't thinking you were coming across any specific way at all. Just chatting.
I know Sherman builds a nasty award winning small block - but I've never seen one in a boat.
I think Joe is retired and the kid is building them these days.
I talked to both Sherman and Gazan at the same time early on and thought Dick had a better handle on where to go with a boat setup.

Next time you come out feel free to bring a sister or sisters friend or something. Waay to much sausage in the rig of late.
Heres the rig in Hotboats 93 calendar - The cloth interior was killer at the river, but lousy on the humid Chicago fox river.
Cant remember the models names (hard to imagine how that could happen)
