Dumb Q here, is their an advantage to buying a crate engine over a rebuilt one from my local Napa guy? Is there some sort of difference in the condition of the parts used in a crate motor?

Usually a "crate motor" refers to a new engine. A rebuilt engine is used. One big difference if we use these definitions is; the crate motor will have standard cylinder bores and standard rod and main bearings. The rebuilt one will probably have been bored out, and the rod and main bearings turned undersized.

 

I agree, that's is what one would believe, crate engines are new, rebuilds obviously used. However that is not the case. Looking at the Ford Motorsport catalog the 600HP 514cid "crate motor" has a used block. everything else appears new. Same with the 460.

The 362 HP 351 appears to have a new block, as well as the 385HP version. The 270/320/345HP 302s are new assemblies.

One advantage going with a Ford Motorsports crate motor is that you know the company you are dealing with. They list what parts are used and it comes with a warranty.

Food for thought....

Here's another site that might help you in your quest for a crate motor. autoengines.com/460_506carbureted.htm I am planning on going with this engine this spring. I feel the CJ heads don't really help much in the lower RPMs. The Edelbrock heads appear to work great thru out the entire RPM range. I will scrap the carb and put either a holley or Barry Grant on also. Hope this helps.

 

The contradictory posts are exactly why I am curious about this. You guys are thinking a little more muscle than I am. I simply comparing the costs of: 1)having my engine rebuilt 2) buying a "rebuilt" and just plug it in 3) buying "crate" engine that maybe put together a little better than #2. What engine? Don't laugh - a 300. I think the 300's are no longer in production (even for industrial applications) and wonder how can a crate engine be a new long block? I've seen rebuilt 300's range from $800 (some site in Texas) to $1500 (local state rebuilder - includes core) to $1600 for a crate (includes core @crate engines.com). I have a couple of factors here - 1) never rebuilt a motor (but have good friends that have) 2) My truck is a daily driver 3) Want to put some performance items in the botttom end for future build up. Time isn't too much of a concern - I'd prefer the best replacement motor. My 300 is a little tired, lifters and valves are making noise and I believe the bearings are quite worn(200K mi). I'm thinking of finding a decent looking long block at the junkyard and starting from the ground up with a shop doing the cleaning, magnaflux, and machining.....or do you guys personally know of a good engine source and I just skip the hassle?

Just one more site for you to look like, they say they have at least one of every american made motor. some like 350's they have thousands. you have them rebuild it anyway you want from bone stock to hi po. You can probably e-mail them and get a quote. I took a tour of there plant once, it was pretty impresive that they could make enough money rebuilding engines to have a facility like that. just thought i'd give ya another option.

 

First of all a 300 I-6 is nothing to laugh at. It was designed for low end torque and longevity. It serves the purpose with excellence. You may want to consider chaging your oil change intervals if your 300 is worn out at 200,000. My dad took terrible care of his and it still ran pretty descent at 322,000. Every 300 I have ever seen gets a slight knock at around 100,000 miles that doesn't really get worse so I don't worry about it. I have heard good things about jasper. I don't know if I would dump a bunch of money into a crate motor. A good rebuild can last as long as a new motor. It's finding a GOOD rebuild that can be a problem but they are out there. You can buy short blocks out there for 600 bucks but what are you getting. I'm willing to bet they hone them out slap new rings & bearings on an ship them out the door. I personally would rebuild it myself but if that was not my cup of tea I would research a lot of different builders. Download the video from jaspers website.

 

Went to the Jasper site. That's the most through engine rebuilder site I've seen yet - with even a video (runs kinda blocky with 56K). Got me all amped up other than the fact they want $2000 and who knows how much for shipping - I'll have to call and ask, anyway thanks for the link. Appeared they know what they're doing there, with a good empasis on QC.
