M28, 2-valve, for '79-82, rebuilt long block, heads by Ollies of Santa Ana, never used (intended as spare for my 928). On stand in storage. No reasonable offer refused. Frank, fzanka@gmail.com

You might want to list what was done to it. Valve grind, I assume. Guides, I hope. New rods bearing? New main bearings? New rings? New Valves? New oil pump? Which seals were replaced? A photo on the invoice might be good.
Plugs are sitting at off angles. That is a little bit off-putting.
...Just suggestions....

What Karl said.

Zero miles on a rebuild is not the same as zero miles....

Hi Frank - What are you using for an engine stand? I've been told a regular stand doesn't work on these blocks but it looks like you're using one? No modifications?

Thanks,

James Bailey

A fully dressed all accessories 928 engine especially a 4 valve is pretty heavy for the average engine stand.....you get flex and sagging and need to fit a support brace under the front of the engine. They just do not feel right

Hey Jim, so does that mean there is no problems fastening a 928 motor to the typical engine stand? I saw some heavy duty ones on Jegs capable of holding up to 1200 lbs. I assume that is more than enough for a fully dressed 928 motor?

James Bailey

correct they will work fine just do NOT try torqueing the front crank bolt while in the air be very careful when moving it around and rotating the engine turning it upside down you will find how out of balance it is !!!

Any engine stand that will hold up a Big Block Chevy will hold up a 928 engine, weight wise. However, the 928 engine seems to be longer or has more mass up front and they tend to be like "candles in the wind" on one of the generic engine stands. Most of the generic engine stands that you will find, online, are built with very thin material and flex quite a bit [because most people are comparing prices (they are cheap) and a stronger stand made of out of heavier material costs much more.] Most people who use these "economical' engine stands prefer an additional brace to support the engine.

The two upper bell housing bolts go into the "Alusil" (Reynolds 390) portion of the block. This material is very brittle, because of the added Silicon, and most people are not very "comfortable" with an "American Style" engine stand (what has four separate "post style" mounting flanges.) And when the lower "cradle" gets removed and only two of those posts are supporting the entire crankcase (with the crankshaft still installed) it gets even more exciting. The "Alusil" material has the potential to break off an entire section of the crankcase, which turns the entire crankcase into scrap metal.




By far, the best thing to do is to find one of the original 9127 engine support pieces (or hope that Hans finishes making these things, one day) and build a really heavy duty engine stand with the 313 head attached to accept the 9127 support.

The only problem....sometimes the correct way to do things is expensive.

I have a HD Princess Auto Stand (Canadian Version of Harbour Freight) and it holds a fully dressed S4 engine with no problem. Where it gets dicey is when you rotate the engine.

It is not whether the stand can withhold the weight, but whether you can withstand the off balanced nature of the motor on the stand. There is a lot of momentum when rotating the motor. I have a bent 3/4" steel pipe to show how much weight and force the engine has went it "gets away from you".

This is where a stand with a crank on it to do a controlled rotation makes sense. I know that Hans was working on a prototype a couple of years ago which I would buy in a heart beat.

Thanks Jim, that makes sense. I hadn't read the fine print to see it was a 2 valve engine. I'm about to pull the block on my '85 so I'm looking at stands (and engines, which brought me to this post, sorry for the off-topic but the pictures were compelling).

There was a fellow recently talking about making an adapter for these blocks and I got the impression the issue was bolt pattern rather than weight. I did notice the WSM recommends a brace so I'm looking around for ideas on welding up a plate for a HD stand I could bolt a brace to.

From about post 3 on, we really trashed the OP's thread. Sorry!

Maybe we should talk about engine stands somewhere else and let this tread go back to selling this guy's engine?

To the OP....I'd think for anyone to be interested, you are going to have to list details....a "valve job" is not a rebuild.

karl ruiter

I just added a 2x4 support under the front of the motor. Of course you cannot spin it in that configuration, but I don't do that very much anyway.

Pfc. Parts

Agreed on both points. Sorry to Frank, but thanks for posting the pictures.
