Hey Guys, just wanted to let you guys know what I have been building/piecing together, as of late. Kinda strayed away from Diesels, actually land in general.

Well here it is.

New GMPP 4 bolt 350
Lunati forged 3.800 stroke crankshaft
Howards Forged I beam rods 5.7 inch full floating
Keith Black pistons
Comp Cams XM270HR camshaft
Comp Gold roller rockers 1.6 intake, 1.5 exhaust
AFR 180 Street head SS intake valve, inconel Exhaust Valve
Edelbrock air gap intake
Clevite H rod and main bearings
Canton 9qt oil pan
and finally some form of Marine(water jacketed and injected) header
Trying to build a 450ish hp motor that will last a long time.

I have not bought the intake manifold yet, still trying to decide on EFI or stick with the carb. Does anybody have a set of CMI SBC headers they are willing to part with?

Nicely done...once it's up and running be sure and post a video. What is it going in? Funny that the subject is brought up as I've been looking at building a SBC to go in an S-10 :woott: I may have to give you a shout if I run into any trouble building the motor.

Sounds like a good reliable combo! I went a little overboard with the sbc that I built for my camaro lol 675hp to the tires was fun but not really driveable

Going in a boat. It's an older wellcraft scarab, my old man gave it to me. Thought I would fix it up, hopefully still have her when I have kids.

With stock 5.7l merc 260hp engine it would run 50mph at 5000rpm. Looking for 65mph at 5500rpm with the new engine.

This motor is for sale 6000. Never been run. Has crower rods. Everything else's is accurate in the OP.

Can arrange shipping.
