Hi everyone,

First time poster here - I've been working on a Glen-L rampage for a few years now and am finally ready to get some iron in it! Apologies if you see this exact same post on similar forums...I'm trying to cover my bases, of course. I have also done some extensive searching on this forum and others to get an idea of everything, but I'd rather get some specific feedback on my application / thoughts before I pull the trigger, if that makes sense.

Some quick background - it's a 20', 1000lb hull, with an SD-309, performance intake (shoe/ride plate), and AA impeller. See below pics on current progress. I'm pretty committed to a 454/496 - I know, I know, a ford or olds will be better to half of you, but I'm a chevy guy and already own chevy mounts / accessories. Lightning water jacketed headers as I can't run twisties on my lake, and I'd like the build to spin my pump at 5k for the next ten years on pump gas without worry...so a dead nuts reliable 550 hp is what I'm looking for. Experience wise this is my first V8 build, but not my first engine and as a mechanical engineer by training I should be a pretty quick learner.

Here's what I'm thinking so far:

-454 block, 4 bolt mains, junkyard.
-Eagle or Scat stroker kit - scat only offers a 489 but if they're head and shoulders over eagle I don't mind loosing 7 ci.
-AFR or Brodix aluminium oval port heads, ~275 cc runner volume, with chamber matched to above pistons to get me around 9.5 - 10:1 CR
-Victor Jr or RPM Air Gap intake
-Holley 850 Double Pumper - likely the marine version as it's a wooden boat and I'd rather be safe than sorry, though the engine is definitely sitting loud and proud in the open.

Notably absent of course is my cam choice...I'm pretty dead set on a hydraulic roller and I need to worry about reversion from the wet exhaust (water *jacketed*, not injected, but the water ends up in the pipe down stream anyways)...otherwise I am all ears!

Please tear me to shreds and tell me I'm out to lunch - I'm not here to feel good about myself, I'm here to learn. And of course, if you guys have any questions or want to see more pics, just ask - and otherwise thank you all very much for the help!

Cheers,

Denon


Overall hull, sanded and waiting for another coat of epoxy / varnish. That's a fake / foam block for mocking things in place.


View from the rear.



The camera does a terrible job of picking it up, but the boat's not black at all - it's just stained mahagony that the camera can't pick up.
