Cola does not make GM's new 3.800" crank
These guys make GM's new 383 crank shaft: http://www.srcreman.com/contactlist.htm
They don't have any V8 stuff listed on the website, but they do list Isuzu quite a bit so it looks right initally. If anyone needs some details on this 4340 forged crank (3.800" stroke, 1 piece rear seal, SBC 350 bearings) you may want to start with the contact list above.
I know this isn't quite "Advanced Tech" but its some good info on those looking for an unconventional stroker, and there was some confusion in previous threads here that Cola might have been the manufacturer (didn't sound right at first, but I didn't have any proof either way, so I figured I'd write a few letters

Thank you for visiting the Performance Parts website.

Thank you for your inquiry.

Thanks for the info,
Who IS listed as the vendor... maybe I can get a load rating for it from them. My 388ci LT1 build-up is borderline for some parts and I really can't afford to put in a piece that can only hold 500 to 600hp.

Comments: I was wondering if you could give me a few details on crankshaft 12489436 (forged 4340 Steel, 3.800" stroke, 1-piece main).
I was wondering if you have a hp rating for the crank? I heard a rumor that this crank is supplied by Cola Crankshafts in California... is this true? or does GMPP run it's own forging in house?

Maybe Cola sub-contracts this crank to Springfield? I'm suprised GMPP even provided the info (usually suppliers for private-label items like this aren't given out). Contacting Springfield or Cola to find out wouldn't hurt.

Just a little update on this crank. I bought one of the cranks that another member was selling. The crank comes in a Cola box and has a Cola Part number, COTS38003A1, one piece rear main seal 4340 crank, 350 x 3.800 x 5.7. Pretty nice looking piece main journals are highly polished and all oil holes have been nicely chamfered.
Now for the down side. I'll be looking for custom pistons because my block has already been decked. If your block is square and ready to go at 9.025 block height, you can find off the shelf pistons all day long, as long as your wanting to do a zero deck.

Re: Cola does not make GM's new 3.800" crank
very cool. 
Do you know off have what the target bobweight is for this crank?
It would definitely help me decide what rods to go with (prices are fairly close, but I definitely don't want to waste money on a heavy piece that will put me WAY off on the mallory).
Also, isn't Cola now called "Titan" crankshafts? I'd heard you were still "the man" there but had a heck of a time getting though to the main number. (http://www.titancranks.com)
I'll send you mail at support@titancranks.com as well as I'm not sure if you'll be checking back here later.

Re: Cola does not make GM's new 3.800" crank
I did some research on that crank last year and I was told that it was manufactured by Cola. I called cola and they confirmed the contract. Maybe they are sub-contracting out and it's their design, who knows? Nobody seemed to have any more info on them. And as far as connecting rod availability, forget it... I went with Scat 4340's but I do have the matching studded rods for these. I've been told the matching rods are no longer available since the manufacturer is having some sort of problem, but GM still sells the pistons all day long.
93ZM6Tally, you have one too? you know you can use most any off the shelf 383 piston there is...you just come close to zero deck and have to make most of your quench with the head gasket. I'm using the stock HT383 pistons for now with my crank since I'm running LT1 heads, which put me .026 down in the hole...but it depends on how much your block was decked and if you choose 1.420 or 1.425 compression height pistons. I've done some looking into this too...
These cranks are nice as hell! Id use mine in my LT1 if I could but I built mine to be used in place of my L98 in my other camaro using converted LT1 heads. Should be nice!

Re: Cola does not make GM's new 3.800" crank
Yes, Cola does, and they made every crankshaft for the ZZ383 engine to date. Cola made over 3000 of these crankshafts and they were shipped to SRC. Cola has the forging die and does make these parts.
