Mykk's BMW V8 T-bucket, version 1.5:

[Mykk]

I was expecting some tolerance differences and not fretting over 0.5 degree discrepancy. I would love to see perfect marks, but variables happen. I did my best to try to align the angle of the dial indicator with the angle of the lifter in the head so they moved equally but the discrepancy could even be in the angle of the dangle. The bank 2 cams have a longer snout on them to compensate for the B1 to B2 offset.

This engine family finds it's way into various performance markets; Alpina, Dinan, AC Schnitzer... Even saw a video of one in a De Tomaso Pantera. Any camshaft variances would have been long picked over 20 years ago.

And that's okay, I knew what I was getting into.

Mykk - It has to be a kick to know that your power train is unique in a T-bucket. I bet you never tire of the question, "What engine is that???"

And that's okay, I knew what I was getting into.

With the power output they are getting out of much smaller packages these days and the weight of the typical T, any V8 is more presence than requirement. Just like an old musical genre, you can follow the 'rules' and make a new tune in that style.
I'm kind of amazed there hasn't been a Track T that follows the style of the 40s with a modern 4 cylinder. I'd guess the DOHC would be too tall.

Got the cams timed today. I swear the Car Gods were messing with me on this one. If a cam was one degree off, I'd adjust it the one degree then somehow it was 3 degrees off in the opposite direction. X 4 cams

Continued to paint stuffs. Painted a valve cover silver. I like it so much more in person I'll run with silver valve covers for now. I can always change them later.

I told myself I wasn't going to do this entire engine in black oxide socket cap bolts. That didn't last very long.







The black oxide bolts tend to eventually rust. So I soaked each bolt in oil for a bit then cleaned off, we'll see if that prolongs the inevitable.

It took me a minute to figure out the motor was not in the car! I thought it was huge! Your builds are so cool!

Progress has stagnated a bit as life just keeps happening.


Had an out of town gig at a motorcycle rally for Az Bike Week. Loaded up Bucket #1 on the trailer, along with the music equipment and headed south for a few days.





Once back home the weather was about perfect and couldn't resist a cruise out to nowhere and back.





Now back in the warehouse, it's time to keep moving forward.











I've had another set of velocity stacks for the throttles; bigger, taller, prettier. The port sizes are good however the bolt patterns aren't.



It'll take some foolery, drilling & tapping extra holes to get there but I think it'll look good once together.

I think I may be painting myself into a corner here, I'm not sure how I'm going to lift this engine with the cherry picker. Burn that bridge when we get to it.

A man of many talents! I recognize those locations!
I found an issue with mine, hopefully it's just the small problem and not deeper.

What did you find?

Broken valve spring. This is my first SBC after a lifetime of being a Mopar guy.
I think I've got away from further damage. Pumped up the cylinder and very little leakdown. No big whoosh out the exhaust. Popped the retainer and keepers loose and got it all off. New spring is coming up from PHX, be here in the PM. They have a spring compressor to borrow/rent.
Then if all is well, back to getting the new intake and carb sorted. We shall see.
