I have owned a 1974 K-10 for over 30 years. The other day I took a starter back to auto zone and they showed the recite around the store it was so old. I have had a couple Bonded Motors in it. I could always count on a good build from these guys out of L.A. I heard they went bankrupt I guess it's true the good die young. The next time I next time I needed an engine it was 5 Star Engine in Glendale Arizona. What could go wrong with a 600 and some change rebuilt. It took 3 tries to get it emission tested and then only passed by the skin of the teeth I was told it was Drop and Go. But that was my fault I took it as being Drop and Go and it would have the valves bench adjusted.

My third day driving home from work it over heated. I pulled over put water in it and waited an hour then drove it on home. I had called Chris with issues on the engine 3 times but this time and tired of hearing his excuses. I set it up to run a compression test. I never got to run the test because water was squirting out of 5 and 7 cylinder.

Blown head gasket, easy. I pull the head and find a grove cut in the block 3/8 " wide and .650 of an inch deep. Chris said he could fix it but would have to charge me parts and labor. He told me it was caused by a lean mixture on an engine with less than 100 miles. I think it was more caused to JB Weld failure. Am I wrong when I say maybe on an engine with 20,000 miles but not 100?

At this stage I knew Chris is one not to be trusted and warranty was as worth as much as the ink that printed it. I tried the BBB but you join the BBB and it all just vanishes. He also got me for a 4 bolt main and I got a paper weight and a long memory. I wrote the first rip off report on Chris way back then.

Of course now there are many rip off reports on Chris owner of 5 Star Engine and Heads, criminal charges are pending of him and his wife taking all the custom parts off some guys car he worked on and replacing those parts with junk.

I found a 94 350 2 bolt I throw a piston in, some rings, and bearings in and got ten years out of. Last Summer it was time for a fresh engine and I went through O'Reilly Auto and I'm glad I did. With about 300 miles I ran a compression check. The right bank was OK but the Left readings were 70 lbs. on 7 with zero on 5. The other 2 were both 40 lbs.lower than the right bank. I got a hold of O'Reilly's who gave me the name Gearhead Motors out of Texas. a phone number and the name Jason. My first and only talk to Jason was first thing he told me his warranty only included parts but no labor. I told him not counting zero in number 5 a 70 pound difference in pressure is not close to being near satisfactory. He replied "Well you know how those 350 small blocks are". Getting to be a real pro on these BBB certified engine as good as new rebuilders I found a hold in the top of number 5 and the cylinders 5 and 7 scared. I took a photo of the problem and took it to O'Reilly's the manager said it was a bad build and he would have his supervisor give Jason a call.

My wife called Jason the second time. It must of been a different Jason and not related to the one I talked to because he told my wife the motor had been ordered and should be shipped any day now.

Right now I have a couple hours before I start it. I found out the damper bolt in the crank had a Helicoil in it I ripped out when putting on the damper. The other issue is something I have never seen before, the manual fuel pump the hole for the rod had been welded or plugged. Anybody know what's up with that? I'm scared to turn the thing over. One thing I know being a half wit week end grease monkey with a butter knife and a pair of pliers that knows how to use them, you should do your own engine rebuilding and buyer beware.

Wow! Someone was just asking about 5 star engines in another post. Sounds like a good engine to avoid!

Yup, reasons I went with a ZZ4 crate motor. Used but it checked out good. It had 10k miles out of wrecked Vette. GM performance and broken in good.

The 350 vortec in my 97 Express van died at 57K miles and its replacement, the Hecho en Mexico "Goodwrench" L31 engine that many of the performance crate engines are based off was the absolute worst Chevy engine I have ever owned. Garbage from day 1 to be honest. Had $$$$ problems that showed up around 40K miles. Like crank journals that were not round.

Crate motors are not assembly line built. Internals are different too. Yea, stock rebuilds and so are not up to good standards. The ZZ4 has has had one major problem. The rock arm nuts get loose over time. I replaced them with adjustable lock nuts. If I don't push the RPMs above 5600 RPMs too long, the push rods will hold up. I plan to drive the ZZ4 hard. It did blow a semi stock 700R4. The current one I can beat on all day and not worry about it.

Must be some of that "silly putty" metallurgy we've been hearing about!

Joking aside, I had an old GM Target Master 350 and TH400 in my '63 Suburban decades ago. Later, I swapped it into a '61 Apache 10. Got a lot of miles out of that engine. When it was time to reconfig the truck again I sold the engine to a friend that knew its history with me, and he installed it into someone's car. Later it spit the balancer off, sheared the key off in the crank. He took the engine apart and discovered it had a whole bunch of mismatched parts including not even close to the same cylinder head on each side, and both heads had small cracks - though no signs of them from how it ran. Go figure.. it ran OK for me for tens of thousands of miles in two different trucks.

The L31 is identical in construction and components to the GM 330 HP 350 HO and the 357 HP SPO357 as well as the 300 hp marine engine. Camshaft and lifters is the only change between them. GM also used thicker head gaskets on the performance engines to drop the compression ratio. ZZx is a little different breed, but those were also based off the L98 Corvette engines.

No matter what you do to a 700r4 short of submerging it as a boat anchor and swapping it for a TH400 will make it reliable.

It was nothing to do with the metallurgy. Everything to do with the crap machining, faulty assembly and tolerances being out to lunch. A rod journal that was out of round on the crank. Then when I opened it up to gap the rings, found compression rings as tight as 0.008" ring gap in 2 cylinders and another cylinder that had more than 0.030" gap. One cam bearing was also installed wrong. I ended up swapping the crank, rods and pistons. Crank is out of a marine 305 that was freeze cracked with 50 hours on it. I used a set of low mileage Mahle flat top LT1 pistons from an early LT1 that still had "X" rods in it. Very minimal work needed to balance them together. Had the block machine honed, new cam bearings and built it correctly myself.

That is on top of the fact the hecho en mexico 062 heads both cracked more than 6 years ago. The hecho en mexico heads did not even flow 220 cfm at peak at 0.400 lift and fell to 210 cfm @.450. The valve springs on them only had 45# seat pressure, which explained to me why the engine would not even rev well to the stock shift points. It has chibese aluminum head castings on it that were assembled with decent parts. Far better than the GM mexican junk that came on it.

It was a yoke.
