I am getting things done slowly.

First, Here are some pictures of Block #2 - This one lasted from about 2010 or so til 2017.
It had no Block fill etc.

It developed cracks at the bottom of the cylinder barrels which let coolant into the oil.
#6 Had 2 Cracks and #5 had one crack - The #5 crack also was shared by adjacent #6.

Lesson here stay away from crack etc.
Old block - Served me well. .104 overbore.
Image

Crack between #5 and #6
Image

Crack on #6 Only
Image

More #6 Crack - Hard to see.
Image

Between #5 & #6
Image

Next I am going to try a "Peanut" Head from Mr. Jeffery:
Image

Maybe it will be better than my old head..
Image

Image

While I had stuff apart and my Glyptal out why not glyptal the inside of the Oil pan too?
Image


Image

Almost Done painting Inside and out.
Image

Image

Image

Image

Image

A few more nooks and crannies to get to with the glyptal then its Assembly and install time YAY!

Cool. There is hope for M-D, eh? I am surprised to see those cracks. I guess the blocks do have weak points...

Maybe I am pushing the boundaries of slant sickness?

No not really... As doc / Seymour say big overbores have their disadvantages - I also dont have an unlimited supply of blocks, so I build what I have.

Well Engine build #3 is done. Its surprising how far off factory keyways are off from one crank to another.

I also had to order 12 pushrod adjuster screws for the 1.6 roller rockers.. the old ones were 0.25" too short with this head. One screw arrived without going through the threadform operation. I called smith brothers and they are sending another.

Here's some pics.. drop and bolt tomorrow.

Everything is Bolted in, fluids are in. Oil pump was run to build over 50PSI.

I had to order Longer Pushrod Adjustment screws from Smith Brothers to work with New head. Ordered 12 screws - 11 arrived with threads and 1 was a dud that missed the thread forming operation. They are sending another soon.

I also noticed that my DIY Autotune 36-1 Trigger wheel was cracked. I run it on a 1" mandrel drive with an 1/8" keyway - I tried to repair it but it warped it pretty bad so it's junk.

I ordred another one (this one is a Holley 60-2 Wheel) it is already 1" hole in the middle without other mounting slots - Hopefully it will be more robust.

I Just need to notch it for keyway and reset the Trigger wheel offset and wheel settings in tunerstdio so After all of that is done it should be good to fire.(hopefully this week)

This has to be the worst Build I have ever done - I must be getting senile as I tried to fire the thing up over a week ago.. Lots of crankity crankity crankity but it would only pop and wheeze..

I got to thinking about the problem and realized that I centerlined the Cam on #1 Exhaust rather than intake.

Well that will cause your engine not to fire.

Other things that went wrong..

-Massive Oil leak on Pan rail / Scraper
-Water Pump Leak
- Smith Brothers sent 11 out of 12 screws with threads
- Discovered 36-1 trigger wheel was cracked and wiggily; tried to weld it - Turned it into scrap, so I bought a Holley 60-2 Wheel and futz'd with some settings in tuner studio.. got that working.

Old DIYAutotune 36-1 6 3/4" Wheel - They start with 1/2" center hole - enlarged it to 1" with a notch for keyway. - it cracked along the egde where it was clamped by spacers. Tried to weld it which made it garbage.
Image

Comparison of New and old wheel - Holley 60-2 already had a 1" center hole - perfect for my Moroso SBC Mandrel drive which uses 1" Mandrel with keyway.

It's nice to have access to the Cam Gear and chain when you cant time the cam correclty on the engine stand :-o
Image


Image

We'll See if engine build #3 with new Head, Block, Crank will be any better then Engine #1 or #2.

We all go through cycles of doofyness. You got it goin', which is the important part! Persistence solves almost everything.
