Hey guys,

I’ve got a freshly built motor to put into my MH, and i need a few pieces:
Intake
Oil Pan
Front motor mount
Variety of vacuum valves/fittings on top of the intake
Possibly a PS pump stud, I think I may still have mine
Probably a torque converter

I can see a few choices for new aluminum 455 manifolds on eBay for around $400, though I suspect they’re not really quite the right thing. Some of them do lack a crossover. Most of them are single plane. There was also a manifold off a ‘72 car for $350 + $50 shipping, but i don’t know much about it, and I think it’s gone now

What is the tallest an intake can be without requiring a doghouse?

—Story below—

As you may (or may not) recall, I’m putting a rebuilt motor into my MH, as the old one was knocking. I pulled the old one almost two years ago now, and found a guy on Craigslist who said all the right things to make me think he would be a good choice.

Apparently not.

Anyway, Grant Schaffer loaned me his hoist, and I pulled the motor.
(Curiously, it was blue, with a ‘74 Passenger Car sticker on the valve cover. My rig is of course a ‘73)
I sent it off with my Craigslist contact, and he never came through. he did, apparently, pull it apart, and discovered a trashed thrust bearing, and recommended I replace the torque converter.

More recently, Grant put me in contact with the guy who built his last motor, Greg Landes of Millenium Motorsports in Temecula, and I picked a motor up from him almost six weeks ago now. It came with a pan, but it’s cracked. My old intake is with the craigslist guy, also cracked (allegedly)

Got any leads? I want to get Grant his hoist back sooner than later.

Sounds like you need four parts off somebody’s trashed engine. Try the vendors.

Here's the best intake manifold:

A bit spendy though. You might be able to find a stocker from somewhere, in fact I have one, but it has the usual crack between the secondary ports. Not bad, but it's there. If you want to make a trip to Tucson sometime we can work something out.

P.S. We're leaving Monday for a six week trip. Barring all that, find a Toronado in a wrecking yard and strip the needed parts off of that.
