I am looking to buy a crate motor for my 67 Chevy II sedan. My only experience with crate engines is a GM H/O 350 I bought awhile back for an old jeep I had. I want to stick with a small block and am thinking about a fuel injected 383. I have looked at the Smeding 370hp fuel injected set up which looks nice. I have also looked at the Gm Performance Ram Jet set up.

Does anyone have any experience with either of these or with any other crate engines? I am not opposed to a carburator set up but like the ease of fuel injection. Thoughts are appreciated.

I put a zz4 in my 67 and im happy, but if you want a fuel injection crate, why not go with a gmpp ls327 crate

I looked into the LS motors and truthfully, I don't like the way they look under the hood. I probably will offend someone by saying that but to me a 350 small block looks awesome under a hotrod hood. The ZZ4 looks like a good motor.

Thanks for the heads up. I guess I could have done a google search as well. I think going the gmpp route is the best way. Any thoughts about that Ramjet set up? I might just get a short block and add a Holley stealth fuel injection set up also. So many choices, he he he!

Gm crate

I got a GM Crate Engine ZZ383/425HP Is GREAT Engine





























ZZ383 Crate Engine 425HP 12498772



SKU: 12498772



RETAIL: $6,632.50



YOUR PRICE: $5,384.00





ZZ383 Crate Engine 425HP 12498772 Description



With GM's legendary Fast Burn cylinder heads and 383 cubic inches, the ZZ383/425 delivers incredible torque with smooth, linear delivery.

If your're looking for a small-block package that delivers big-block power, then you've found it.
425 horsepower at in incredibly low 5400 RPM, and 460 ft.lbs of torque at 4500 RPM make this the ideal hot street engine.

The excellent air handling and combustion characteristics of the Fast Burn cylinder heads combined with the ZZ383/425's 3.800" stroke, make this engine the benchmark against which all other 383 inch small-blocks should be measured. And its tough, too.

The 4340 nitrided and induction hardened crank and unique forged PM rods see to that.
The 9.6 to 1 compression ratio ensures that the ZZ383/425 is 92 octane pump gas friendly.

The ZZ383/425 gets a stout .509/.528 lift steel camshaft with 222/230 duration at .050 lift. Hydraulic roller lifters and GM's time tested 1.5 to 1 roller rocker arms round ou the valve train.
And, of course, it has the Fast Burn head's lightweight stainless steel valves and retainers for reliable performance at extended RPM.

GM's testing was completed using a GM single plane intake, P/N 12496822 and a 750 CFM Demon carburetor with mechanical secondaries.
Test header specs are: 1 3/4" primairies,33 inches long with a 4-inch collectors.

GM dual plane intake P/N 12366573 may be used for hood clearance on the ZZ383/425, but it results in a decrease in peak horsepower of approximately 15-20 horsepower.

Roid I am liking that engine!!! Are you running it with a carb or fuel injection? The first engine I thought of was a 383 way back when I started this project.
