Postman has been with some goodies

[Jonny69]

The postman shoved these goodies through my letterbox on Friday.

1200 block and some steel mains:

Lightened rods:

Lotus pistons:

Lightened flywheel (so I can stick with an Escort style clutch):

Stock cam on the right, new high-lift long-duration one on the left:

Hopefully, with the nice weather we're having, I'll get it screwed back together and maybe back and running before I disappear off to Bonneville. Famous last words, should know better by now etc etc.

Look forward to seeing how you get on!

Big letterbox you have there..

Should have seen the size of the postman's arms

And a strong postman.

Curses, beaten

How long will this one last?

It's nearly 50 years old, there are 3 bearings in the crank and I'm keen for well over 8000rpm... NOT VERY LONG

Right, where is the thread i am obviously missing?

 

[Jonny69]

All my pics are long-dead Rybo, so the old thread isn't worth dragging up. It's going in my Anglia:

How many horsies?

 

[Janesy B]

I'm guessing 85bhp

 

[Jonny69]

I'm aiming for 100

Cam profile is good for 4500-8500rpm. I was going to go for the old Cosworth A6 grind, but it's a bit peaky and 9000rpm might be a bit much to ask from a 3-bearing cast crank. Assuming the head can let enough air in, and it'll be wearing twin Webers and a big 4-into-1 manifold, I shouldn't be too far off that. Hopefully

I could get 100hp out of it with something like the Kent 244 or 254 cam, maybe more, but I didn't want to use a modern grind. I'm looking for that 'old engine' sound that you can only get with loads of duration and lots of overlap, but the older grinds never made as big numbers as the new ones do.
