I tightened the fitting on the filter relocator and that fixed the leak.

I am really really happy with how this has turned out.

Sounds good does the Air cleaner and Filter clear the hood when closed?

Well, it does because I have a 68 Hemi Dart scoop on the hood. Very Happy

Took it for it's first few laps around the parking lot. Oh boy, she's rowdy. Started to do a burnout, but it almost ran out of gas. I was lucky to get it back in the shop. Really reminds me of the original 545. Throttle response is NOW.

The oil filter adapter continues to drip, so I gotta take it off and fix it right.

like the motor mount setup you used instead of a full block plate i might do something similar . did you do a mid one as well.? also how did you attach the bent tubing to the aluinum plate behind the water pump? i should put some pics of as i am doing twin turbos in my maverick right now , almost done the turbo stuff just 4 bolted a dover block and getting ready to awap all my internals over to a 4 bolt block than i can put engine back in and get things hooked up .

I looked at a bunch of 460 alternator mounts last night and It seems like every one of them was flat and used a bunch of spacers to move the bracket out to the alternator's mounting plane. I didn't particularly like any of them.

After I made the cardboard version, I cut this one out of a piece of flat steel with my bandsaw. Then I bent it in the vise with a big hammer. Kapow.

This one is not finished and I'm not sure if I'm going to leave the adjustment arm in that position, but you get the idea.

I didn't make a mid mount.
The plate bolts to the bar with 5 bolts. There is also 1 bolt on each side that goes into the heads. Those two are really there so I can remove the plate and timing cover without having to support the engine some other way.

I drove it on it's longest drive today. The tune is still garbage, but I data logged it and will be making changes. I am going to turn the target AFR table off because I believe it is jacking with me. I drove it long enough to get it out of warmup enrichments.

It's mostly garbage, but when you whack it and it hits a happy spot, it totally rips. REALLY excited about this version of this engine.
