GM Crate numbers ? Can't work out what I have bought?
 

I bought a crate motor with this part number and specs
GM12486041-1

CRATE MOTOR SBC VORTEC 330HP
H/ROLLER

Small Block Chev 350 c.i.d 330 Horsepower Crate Engine

But when I put that number in google search I get 350HO come up which is a flat tappet cam motor?
Does the -1 at the end of the part number mean its a roller cam motor
or is this listing incorrect ?

Are you wondering if your motor has a roller cam? You could pull the distributor to verify

Re: GM Crate numbers ? Can't work out what I have bought?
 

Mine does not have roller cam.

Re: GM Crate numbers ? Can't work out what I have bought?
 

Have paid for it but it has not been shipped yet and if it is not a roller cam I don't want it.

Re: GM Crate numbers ? Can't work out what I have bought?
 

does your part number have -1 after it.
i thought -1 was just a marker for long motor.

Re: GM Crate numbers ? Can't work out what I have bought?
 

No. I bought mine from Jegs, and they have their own part number system. Plus, I got the "turn key" motor, with carb, intake, started, serpentine system, etc.

I think either your supplier has a typo on their website, or it is an Australia only thing...

I found this...

Your supplier is the only reference I can find that specifies a roller in that motor. I find that unlikely.

Why do you want a roller cam?

read this!. It didn't have the one after it but the same number and is a GM Performance engine. Flat tappet cam. http://www.summitracing.com/parts/nal-12486041

Why wouldn't you? They are better in every way except initial cost. If you can get one at a price you can afford, it is the way to go.

Re: GM Crate numbers ? Can't work out what I have bought?
 

When spending alot of money, its a good idea to make a phone call to ask questions before hitting the buy it now button.

Re: GM Crate numbers ? Can't work out what I have bought?
 

I did call and asked them to double check the cam specs which he said is H/Roller.It was only when i entered the part number from the invoice in google to get full specs that I realized something was not right.

Re: GM Crate numbers ? Can't work out what I have bought?
 

because in a thread 3 days ago all he wanted was a mild 350 to now 330hp isnt enough :lol:

Re: GM Crate numbers ? Can't work out what I have bought?
 

Yeah true but I bought this motor for $2900 which is the same price as a 260hp crate here and on top of that I thought I was getting a roller cam which all seemed too good to true which it was!

But hey 70 hp and 76 ftlbs of torque free I should still be happy.

Re: GM Crate numbers ? Can't work out what I have bought?
 

Oh I agree you made a great choice, that's a nice engine you bought. Maybe it has roller tip rockers and that's what that means

Turned out the part number was wrong because it is in fact a roller cam motor.
The supplier made the mistake and has agreed to live with it.
Lucky me.:lol:

Heck of a deal...congrats :metal:

Re: GM Crate numbers ? Can't work out what I have bought?
 

You will love that motor

Re: GM Crate numbers ? Can't work out what I have bought?
 

Congrats! That's the same engine my dad bought for his 85.

Re: GM Crate numbers ? Can't work out what I have bought?
 

post pic of it since now..it's thought to be a zz4..either way..you got a strong mouse..

Re: GM Crate numbers ? Can't work out what I have bought?
 

What ever it is I won't need to dyno it because it has more than enough even at this stage (400 miles on it) to power my old truck way too fast.
I took it easy for the first hundred miles around town.Just reasonable load not much past 3000rpm and varied engine speed.After that I have been increasing the load but not going past 4000rpm for more than a few seconds.I will now change the oil and filter and then give it a few full throttle runs.Getting 12.5 miles to the gallon at he moment which I think is pretty good on a new motor and me getting into the throttle a bit?;)
