Y Block Question

Thanks Riley, I think the debate over original color will rage on forever. I researched this site and others on correct color and found a multitude of answers, so I admit it, I took the easy way out. Now all I need is my hull back so I can put it back in. I'm afraid I may have made a mistake with the shop that has it, he has yet to start any body work. But yet I cannot imagine why, it was 111 degrees here today and his shop is not air-conditioned. Thanks again.

Real nice Job Jeff

I don't care what color it is that is a very nice job of detailing. Your should be proud.

Pete, I painted the Hemi yesterday but I'm going to make you wait for pictures.

Actually it's a different make, I posted about it in the "off topic" section a few weeks ago, Glastron Saberflite.

Jeff, Fresh info from the Boat Dr, be careful as if the wrong pigment combo is used on a Y Blocks over time will weaken the metallurgy and course major failure but even with this damage was able to chug back 6 miles to the dock, always keep it original like Pete said

I want to know what Billy did with the center main cap. I didn't see if he found it in the pan or not. It's got to be there!!! I can sure see why the crank snapped with it missing!

Pete, the main cap was removed to show the extent of the damage .
Bruce, the engine is a 312 in my Starflite.

Ugh! What caused that? We ran ours hard yesterday for the first time and I had my fingers crossed the whole time hoping it was going to stay together. That sucks.

I guess the next one will be red.

What would cause such a failure. Too much power for an old crank?

There are "Y"'s running with blowers without problems but, according to John, there was a era when Mercury {who was building the 292's at the time} did have casting problems. Billy correct me if I'm wrong but didn't you tell me you used a 292 crank that did come from the Mercury crank problem era?

You would think they would have all broke by now. I didn't realize 312's and 292's used the same cranks. Aren't the strokes different?

It appears there was a new short block purchased in 1964 for this boat, original motor puked #7 rod , damaging the alum. oil pan .There is a small repair on the flange. It is indeed a 312, w/ FoMoCo std. rods and mains. There were some issues, I was told, with the older castings, so maybe this unit being new in '64 could well be in that time frame.
There are only about 40 hours on this engine,very pleased with the power and performace the 215 hp provides.
I am building a 292 to swap for the rest of the summer,this is a parts and pieces motor, a little time and we will see if it will live,

This wooden boat stuff sometimes sucks,,,,,,,,

Pete the 312 block is a one off, as is the crank.The compression increase is a result of the shorter deck height, and increas in bore and stroke.
Also found there are as many hidden ponies in a 292 as in a 312, over bore to .125 safely......lets see what happens come winter,
