Hard to believe - but Tony, I've finally seen something sexier than your avatars on these boards.

Buddy, Dale - That's ONE BEAUTIFUL ENGINE!

Like I said, it makes my man parts tingle.  You guys have built some serious  EYE CANDY. Tony

Thanks for the two-piece head education. Wow... somebody's better with a manual mill than I am! :-D :-D

The snout support will undoubtedly help. With some foresight (or glancing at well-engineered ones) though, it could help much more; not much rigidity to a "plate on pillars". Just my two cents...

We can swap the lower-upper pulleys and switch over to a 48 driving 53 pulley setup, but if we want to run a larger upper pulley during breakin, we'll need a longer belt.

Longer belt?......... what are ya gonna get , a conveyor belt?

You took the words right out of my mouth regarding the rigidity of the "plate on pillars."  You could stiffen it up by replacing the "pillars" with a rigid rectangular plate on each side with three holes for the bolts.

Regarding the rest of the build, it showpieces the talent and dedication of the members of your team.  You are to be congratulated.  Of course it has caught my attention from the very beginning, because my first car was a '37 Chevy with a '57 Pontiac motor.

It's hard for me to argue the point. I'm not fond of it in the first place-I think it looks like a spider humping the crankshaft!

Still, we felt we needed it, and I think it will do the job.

It's an off the shelf piece from Fowler Engines, for BBC's. If it appears to be letting the crankshaft move, we can plate between the 'pillars', or make a stiffer one.

The engine is very tall, but sits so low in the car, it doesn't appear as tall when installed.

Buddy,
That thing is a beast!!! Pretty, but a real beast. If it runs half as good as it looks you will make tons of HORSE POWER!!

Not much matters and the rest doesn't matter at all.

We'll see in three weeks if it qualifies as a race engine. If not, I'll see if anyone needs a trailer queen engine! :evil:

Sweet engine!  Now, if you could find a vintage Cadillac roadster to put it in!   :mrgreen:

Lateral stiffness is nearly as important as vertical. There appears to be enough elbow-room to enhance both.

  Great looking engine and work,can't wait to see and hear it at Bville.
  Is part of the breakin for the cam and solid lifters? there should be little or no boost at a steady rpm untill
you put a load on egine or blip the throttle.

Yes, I want to get the cam and lifters broke in good, before we add too much load.

Thursday Evening Update: Magical Mushrooms . . . Psychedelic Man

I've just finished the work on the 'magical mushroom' lifters. We've replaced the stock hydraulic mushroom lifters with some flathead Chrysler mushroom lifters. I got the idea from Barney Navarro about 25 years ago - to put them in flathead Fords . . . but they actually work really nice in the FlatCad. The bigger the lifter base diameter, the faster the cam opening ramp can be (which is good on a flathead - no rocker arms to multiply anything!).

1) The length is just about perfect.
2) The body diameter is smaller than the FlatCad valve lifter blocks, so Buddy had the lifter blocks bronze bushed for me.
3) We have about .0015 clearance

The cam pattern was designed for a 1.260 lifter diameter, so I had to turn the bases of all of them down on the lathe - about .023 reduction in the diameter. As you can imagine, they're harder than hell, but good ole' carbide was able to cut them . . . just took a long time.

We have 20 lifters (4 spares) . . . glad this job is over . . . boring as all hell.  

Tomorrow I'll be fitting the lifter blocks, lifter block girdle supports and hopefully finishing the valves by sometime Saturday.

Chris is coming over on Sunday to help with the plumbing - probably while I'm working on the dry-sump mount (which is a real PITA).

Here are the lifters . . .
