Even though cv's allow steep angles, that doesn't mean you should, conservative driveline angles are always better and more efficient. True, but since I'm not horsepower limited, I may have better times on the Steam CEVS EVOC Monaco challenge by having the motor a few inches lower, even though it results in less efficient driveline angle. That doesn't do me any good though, if the CV wears out before I can complete the course. I'm thinking "low enough to get the intake to fit with a few inches to spare", and not "as low as possible while maintaining oil pan clearance to road". I was looking through this thread of yellowbullet "post some nova pics" www.yellowbullet.com/forum/showthread.php?p=7595963#post7595963And there were some absolutely beautiful motor pics in there. Crank angle seemed to be typically approx horizontal: To quite a bit nose down: second pic of that same car: I asked the owner via a visitor message if the motor was in its installed position, asking about the angle, and he said that it was installed about 1.5 degrees nose-down. Not that it's directly related to my setup, but I thought it interesting.

I was thinking about motor plates and mounting, and had a thought about fore/aft positioning. The transmission tunnel is quite small: from bluesmobiles.proboards.com/post/3375with the motor in the stock location, using a 4L80E instead of a 727 would require enlarging the tunnel. If I moved the motor rearward and down as far as possible, it would also require enlarging the tunnel. But there's tons of room to move the motor forward: from bluesmobiles.proboards.com/post/3281Moving the motor forward wouldn't be good for handling. But if it allowed me to keep the stock trans tunnel, and stock cop rubber flooring, it might be worth it. And it might even uncomplicate the engine compartment (more room for headers between the rear of the heads and the firewall / master cylinder). It will be interesting to see, given that I can lower the motor significantly, how far forward it would need to go in order to keep the stock trans tunnel (or at least sufficiently stock that the cop rubber flooring kept the same profile).

Update on the motor:
Lifter company got the lifters and said they were stuck, and found the cause: a contaminant they think could be the black coating they apply to the lifter cup. Their tolerance is 0.0005 (and the reason why they make more power because they bleed off less than other lifters -other companies use a tolerance of 0.002 and they bleed off the oil much faster). They cleaned the lifters and cycled them in a machine.
They said the oil Muscle Motors was using was thicker that they thought it would be and may have contributed to the issue. They asked for oil sample and it was good and clean.
MM partially disassembled the engine and checked the bearings (they are good and don't look like anything went through them). They checked the in-line filter for the dry sump pump and found aluminum debris in the filter. This wasn't the same type of debris found in the lifter. The dry sump pump had a clearance problem on the ends of the shafts, and the filter caught the debris and didn't send it to the motor. MM sent the dry sump pump back to the manufacturer, and waiting for it back.
I'm pleased with the updates I'm getting from Scott, the Muscle Motor guy I spent time with on the dyno. I wish I'd asked for his e-mail earlier.

Sound like progress! It also sounds like Muscle Motors is working on trying to get it all working. I can't help but wonder if the oil pump was calibrated for a thinner oil as well? Much like the lifters, if the pump were designed for a lighter oil it would seem the tolerances would be tighter. Then when a thick oil is introduced it may cause a clearance issue on the ends of the impellers.
At least they figured all of this out n the dyno.
Is Muscle Motors the same place you sent me on the "monaco madness scavenger hunt" a couple years ago? That was a long day.....

Sound like progress! It also sounds like Muscle Motors is working on trying to get it all working. ... At least they figured all of this out n the dyno. Right on, my thoughts exactly. Is Muscle Motors the same place you sent me on the "monaco madness scavenger hunt" a couple years ago? That was a long day..... Yep, same place. I think this motor process would go a lot smoother if I could go back in time with what I know now. But I guess that's true for most everything in life.

^ That's an interesting little item for the Monaco Museum of Amazement Thanks 58HF and Steam. That is interesting. The seller "atlantatony" has 1130 vintage "style" decals for sale www.ebay.com/sch/Automobilia-/14024/m.html?item=321204202120&pt=LH_DefaultDomain_0&hash=item4ac9432a88&_ssn=atlantatony2009that all say something along the lines of: > this is a brand new peel-and-stick style vinyl sticker which appears to be a modern re-issue of an old 1950's travel/souvenir decal Surely with 1130 different style decals, he knows if they are a modern re-issue or not. That Marin decal is neat, but instead of buying a modern re-issue decal, I think I'll just print it out on my printer, and put it in the MMoA. I'll keep you posted with a pic.

They expect to dyno my motor next week. Tomorrow, Tomorrow, we'll dyno, tomorrow.

So what changes have been made for this run?

So what changes have been made for this run? I'm not sure. The e-mail I got seemed rather cryptic. Someone died, and someone took their place, and some heads didn't flow as much as they should, and they redid them. I couldn't tell whether they were saying that MY heads were redone, or if someone else's heads needed to be redone, which put my motor effort further back in the queue. I figured I'd just try to stay calm and wait until next week.
