Has anyone heard of a JET crankshaft for a small block chevy? Seen a crank today with JET molded into it and never have seen one before.

i have one...jet was some how affiliated with lunati. all of the older lunati cranks have "jet" on them. they are good cranks.

Yes, the "Jet" cranks were originally made in Japan back in the early 80's. Haven't heard that name in a while.....lol

I bought a Lunati kit in 1985 that had a jet crank by LA billit.(fully counter weighted job) I don't think it was foreign though

Yeah, LA Billet was importing the raw forging's from Japan at that time, and finishing them here. They were very good cranks, and we used a lot of them in those day's. After LA stopped importing the Jet forging's and they became extinct, we switch to Tennessee Engine Works (BRC) for several years until they sold out, and their quality went in the toilet.

Thanks guys for your input. I found out this week that the guys that refreshened our engine traded us crankshafts without us knowing it. We now have a 10-10 ground 15 year old crankshaft instead of a std lightweight shaft in our possesion. Needlss to say he's not getting any of our business from now on. I guess a fellow should mark all of his parts, but in a honest world you really should not have to do that.

I'd be taking that engine to another builder and having it checked. If your current builder is swapping parts on you who knows if he's not putting something together right so it'll blow up and you'll be going back to him to have another engine built.........

I gave up on other people building my engines for just that reason. I had a 365 ci Chevy in the shop for a refresh and got it back in the car and after about 10-15 warm up laps I started to get into it and it came apart at about 3600. When we got back we called the builder and he wanted us to bring it right back. We pulled the head and pan and found a 400 ci block, Stock 350 cast crank and cast pistons, Not exactly our Lunati crank kit we had. He offered no reason for it and after about 2 weeks and a lawer phone call we got our stuff and money back.

On the subject of cranks, can anyone tell me if 305 cranks and rods will work in a 350? And is a 327 crank and rods the same as a 350?

hey flat,

the 305 rods and crank and rods are the same but weighted different, (lighter). I run a 305 crank with my light weight rods and pistons and dont have to balance as much. the 327 crank has different stroke cant remember what i think 3.25?? have to look for sure.

I always stamp or engrave ALL my parts before taking them to the machine shop. Another good thing to do is let the shop know that you want to look at the assembled engine before they put the oil pan on.

A 305 is balanced different than a 350 it wil work but you have to get the motor rebalanced.
