vortec headed 383
 

So I'm set on building a 383 for my 2001 Glastron GX205 this winter/spring. This is what I'm thinking.

Scat rotating assembly 3.75" stroke, 5.7 rods, 18cc kb d shaped pistons.
GM Iron 062 Iron Vortec Heads, may step up to the GMPP Small Port Bowtie Vortecs (not sure yet)
Crane Cam 2032 2032 Hydraulic Roller Camshaft for Chevrolet 1987-1992 V-8, 305-350
Possible Crane Cam HR-284-2S-12 IG Hydraulic Roller Camshaft for Chevrolet 1987-1999 V-8, 305-350
GMPP Vortec TBI Intake Manifold

Was originally thinking the second cam but would like to be able to run this on a GM tbi system and not sure how the efi will like the second cam.

I will be running thru hull exhaust as I 99% of the time boat on the Grand Traverse Bay, traverse city, MI so there shouldn't be an issue with noise complaints. May eventually install a captains call system depending on how loud it actually is.

Outdrive is a Volvo Penta SX 1.5:1 ratio.

I'm not really putting a budget on this build but it has to be realistic (you know what i mean)

Just looking for opinions or suggestions on my parts list.

The EFI /TBI will handle it with larger injectors and a Re-Program. If your not inclined to modify that...go with your first cam to play it safe.

Sounds like a solid hi-torque cruising build.

I know i'll have to play with the tbi system. Do you think the second cam (the larger one) will work with the tbi system and not cause water reversion?
