Scimitar Project
 
 

The inside is all done, and I got the motor back from the machine shop ... Finally,  I'll get started on it tomorrow,  ain't it Purdy !

It's been a while since I built a motor with all new parts,  this one is a 2000 350 Chevy vortec, four bolt main block,  bored .060 over and micro-honed, forged pistons,  good rods, the heads are 64cc vortec heads milled .010, stainless steel 1.94 valves, teflon seals,  the identical cam as I had in the other one, but I'll be running the 600 cfm Edlebrock performer carb this time on the alumimum performer dual plane intake manifold, and the same ThunderBolt ignition.

The hull mod is done,  I raised the drive 2 1/2 inches, and moved the transom back 5 inches and changed the angle of the transom from 12 degre's to 8.  I'm suposed to get the new drive back this week ... we'll see,  he's said that for two other weeks, it's a Gen II also but a 1.47 ratio.

Hp ... ?  who knows,  the motor was 340hp stock with an 8 to 1 compression ratio and fuel injected, I've raised the compression to 10 to 1 at least with the flat pistons and the bore, maybe 10.5 to 1, the cam added 135hp to a stock 350 Chevy carborated engine on a dyno.  The guy's at the machine shop said if it's set up to spec's the motor should produce 400 to 425 hp easily @ 5000 rpm.

Will it require a Pilots license to operate it?

That sounds great. Have you got a plan for your prop yet, or are you going to feel it out?

Hey Glen,  no license required,  this sucker is stayin in the water this time.

Hi David,  I think I'll be able to run the same prop,  I Hope, that thing cost $470.  But I got a buddy that owns the prop shop here in Okc.  The prop I've been running with the 1.84 ratio is a 15 1/8 X 27 pitch Solas and turning 5000 rpm with it,  it's identical to the Enertia design,  I was running one when I first got the boat with a 1.47 ratio Alpha,  it was a 13 3/4 X 22 and I was turning 5200 rpm with it,  but I got about a hundred more horse now,  we'll see.

Power steering? Where's the ac compressor?
That's a great looking motor.

Looking like you've been a busy man! REAL interested in what results in the changes you made to the transom and angle of the drive. Incredible work Red. So, that man cave is proving it's worth huh?

Thanky Mark, it has been quite a project,  I'm glad it's winding down.  I got the coupler milled down today to fit into the crank, and the motor back in the boat and bolted down,  it's gonna stay in this time,  I'll start dressing it out for the start-up tomorrow.  I got held up a little today trying to find a machine shop that that had a lathe that would swing  the coupler, the tri-angle mount on it is 14" across,    but when I found one they were able to get right to it.

Glenn is coming up Thursday for the lake test,  thats  exciting,  we're gonna have a christening for it.  We'll get a couple video's,  you're welcome to come join us.

OH Red. Thanks for the invitation to join in the fun. Work schedule won't allow that, but I'd love to be there. I hope all goes well!
