Yes I agree don't waist money on crate motors. Get something an exp builder has put together. Both of my motors came from the same guy and never had minutes problem out of them. 40 years of exp is way better than a bunch of mexicans putting the crate motors together. Lol
When I go to the track I know my motor will stay together. That crate motor might last 2 passes or 200 you never know. Anything made in mass production like that is not taken into detail like a custom job so your taken a gamble especially if its never been on a dyno. As far as the warranty goes what the hell good does that do when your stuck on the side of the road? Not to mention the fact you have to pull it all back out to send it back. Its just not worth the risk especially for the prices they sell for.

Other than the 454HO upside rings/no torque plate honed problems, the GMPP motors are pretty successful for the most part from reading the forums. I have no experience other than the two GM crates Ive had. If I did it again on a budget I'd get one of Marks motors though, just wondering.

Frank, the problem with GM crate engines, as well as World, and just about every other mass produced crate engines, is that the guys building them will never have any contact with you the customer no matter what happens, and so it's completely impersonal. They will never have to answer to you as the end user of that engine they build, nor will their supervisors either.

But with Mark and Mike, ("Vortecpro", and "Wolfplace") if you're one of their customers, even if you live clear across the other side of the country, they will be communicating with you directly over the telephone, as well as through this board if you frequent here as much as most of us do, and so they will be in direct contact with you before, during, and after the engine sale and delivery. And it's they themselves who will be building your engine. They will be the hands-on guys.

If for instance there's something not quite right with the heads or the block, both Mike and Mark will see to it that it will be taken care of, BEFORE the engine is built. Do you really think that same care and concern for you the customer will go into ANY GM crate engine, or any other mass produced crate engine? NO WAY. So when it comes to GM's or other companies' mass produced crate engines, it's a matter of Clint Eastwood's "Dirty 'Harry's" words: "Do ya feel lucky punk?"...because you'll have to be one of the lucky ones to get what you pay for.

$10,000 for a bicycle me do not even knew there was custom bikes, lol.

Listen to these guys and have a good shop build you the motor. This way it will be "custom" built to fit your needs and likes. You need to know little, that is the shop job to advise and guild you along. You may even learn a bit more than you do now.

I suspect you're wrong as hell. Stock type motors go together like a wet dream compared to race engines, and are fun to build every once in awhile. You may well make a builders day if you ask.

Exactly.

Why would you pay twice the price for a mass produced engine that makes less horsepower and torque than either of Mark or Mike's engines?

HERE is one of Mark's engine that has 27 cubes less, but makes 69 hp and 21 lbs tq more than the ZZ502.

If that is not enough for you, then get one of Mike Lewis's engines.

And again, you know it will be done right the first time.
