The ZZ4 has a lot of bang for the buck. Nice aluminum heads, roller cam, and a pump gas friendly compression ratio. You can put the original on a stand or rebuild it for when you sell the car.

Crazyhorse,
Did you forget to add the URL to your message? I didn't get who you got the info from.

OK 61 maybe I don't know what I'm talking about , but how would adding a few squirts of oil into the cyl and then repeating the compression test fix a leaky valve? Remember I said that the compression then held at 170 psi after the oil. From the books I have been reading, when you do what I have done by adding the oil, its classic case of bad rings. The same diagnosis was also done a several weeks earlier by a local Corvette R & R place and they also did a leak test to confirm.

396 RAT,
BIG thanks for the info. The GM site I was at earlier didn't have the same info as this one. All I could find on the crates were the part numbers for all of the parts used on ZZ1-ZZ4's and no $$. Well that ZZ4 looks like one heck of a nice motor! It looks to be just a little out of my range tho. Wonder if I'd be happy with the 330HP? My local dealer wants $2200 for this one. If I don't have to pay the sales tax on the Ca dealer then they would be the cheaper.

I do like the idea of looking for a 327 block and parts to do an original on a long term project while driving the crate. I was already thinking of getting a 327 block to do the rebuild but afraid of getting junk and having to start all over again. More money and more time wasted.

I have not heard anyone say to use the Performance Motor Rebuilders. Mostly say use the crate or do rebuild myself. :confused: Hmmm........ thats not exactly what I expected. To many bad experiences with these guys or just not enough responses ??

Crazyhorse,
This is a great source of info and seem to have good $ on engines and parts. I just spent over an hour looking and reading the site. Looks like they know what their talking about. Do you know anyone who has bought any of their engines? I plan on calling them tomorrow. A BIG THANKS ! :chevy :yesnod:

I usually don't get involved in these, as soon as guys mention slow *** 383 crate motors.

My suggestion involves doing it yourself.

Thus buy like the ZZ Short block and do the top end stuff yourself.

Avoiding sales taxes in California!

Anyways, I hate when a guy is shopping, but doesn't even know anything about the engine in the car, except for a code, and running condition, or tests done, not running.

You should already have that thing plucked out, before starting a rebuild discussion. 2 or 4 bolt main, what slugs, crank, rods, etc.??????? Condition of the heads, how are the heads built. Etc. If you aren't prone to take that oil pan off and start looking, you should either buy a crate, or spend money to find someone to do it all for you!

And it only took 20 years to answer this question. As they say, better late than never.

If you have a place to work, and a little time, building a Chevy engine is easy and fun. Take it out (free), disassemble (free), have a machine shop do their magic ($700-$1,000), new parts ($300-$600), assemble and install (free). You will have $1,000 to $1,800 at most in it. It doesn't take a genius to build one, I'm proof of that.

Another option is to buy a 90s vintage 350 roller cam motor. They're a cheap rebuild and they last forever. The RV can that was mentioned will give good street performance.
