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 330 Horsepower, 380 ft. lbs Torque (Hydraulic Cam, Cast Iron Vortec Heads) * Hp: 330 @ 5000 Rpm * Torqu e: 380 @ 3800 Rpm * Late-s tyle Block With One-piece Rear Main Seal * 4-bolt Main C aps * Cast Iron Vortec Cyl inder Heads With Centre Bolt V alve Covers. * Hydraulic "d ual Pattern" Camshaft * 9.1 :1 Compression Ratio camshaft lift: .435" in / .460 exh duration : .212" in / .222" exh 1.00 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 ? http://www.outlawspeed.com.au/shop/i...c77e8970452d77 |

Re: GM Crate numbers ? Can't work out what I have bought?
Are you wondering if your motor has a roller cam? You could pull the distributor to verify

I think either your supplier has a typo on their website, or it is an Australia only thing... I found this... Posted via Mobile Device Your supplier is the only reference I can find that specifies a roller in that motor. I find that unlikely.

Re: GM Crate numbers ? Can't work out what I have bought?
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?
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. ![]() |

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? ![]() |
