Default Almost ready for the break-in

So, it's a carb setup, but I thought you guys might still like a pic. I'll have more as it approaches break-in (this weekend if all goes well). Breakin it in through open headers/turn downs for now. Then it's coated-headers, X-pipe, chambered mufflers, and Side Effects

Engine:
http://s86.photobucket.com/albums/k1...rojects006.jpg

BG 650 Double Pumper w/ electric choke
Weiand Stealth manifold
383, 4340 forged crank, Hyper pistons, polished stock rods machined for full-floating pistons
224/234 @.050, .465/.488 lift (want more, but heads won't take it yet)
Ported 462 Heads, 2.02/1.60 valves, bowl work, minor polishing
9.6:1 Static CR
Hedman Elite coated LTs
RAM 3200# PP and RAM clutch disc

Can't wait...

Oh, yeah, almost forgot. The air-pump and AC compressor are gone. The water pump is standard rotation now instead of reverse. The alternator bracket is custom machined (by myself) and slotted for tightening. Belted it up tonight and it works great.

Same cam im running in my 355 blower motor. Sounds nice but could rump more. Has a 114LSA for good idle quality and pulls to 6k rpms. The heads aren't junk either. The cam and heads are fine,heck its a street car! I think it will scream and run hard.

I thought you'd never finish! I've been waiting for this at the crossfire forum.

Why'd you switch from reverse rotation WP to standard? I didn't know that could be done because of the impeller.

My serpentine belt now goes over the WP pulley instead of under it. It used to go under the WP, then around the AC compressor, then the air pump, and finally the Alternator. Mine now goes over the WP pulley and straight to the alternator. THis turns the WP the other direction, so I switched to an 82 WP which is standard rotation.

I did a similar thing (removing the A/C and AIR pump). I ended up just installing a standard rotation impeller in the stock pump, and modifying the P/S bracket to accept the tensioner. Cleaned things up a bunch.
Keep us updated on your progress!

I'm trying to visualize what you guys have done. How changing the belt from the bottom to the top of the water pump makes the pump turn in the opposite direction.

Think I need another cup of coffee and chew on this a while. I've got to be missing something.
