78mm crank?

any recommendations on where to get a good 78mm crank. The one at
Aircooled.net is rather expensive and I'm not yet convinced that I need
to spend that much.

is your heart set on a 78?

I hear good things about DPR welded cranks...

john has the bugpack(4340 chromoly) for 300....
CBPerformance has their super race crank(4340 chromoly) for 290
CB has their 4140 chromoly in 76 and 74 for 180...

we carry 3 different 78mm cranks. The Flanged one is like $1400
(totally overpriced IMO), but we have a 4340 crank for $300, and a
precision welded crank for $450 (it specs out nuts on, that's why they
cost more).

I strongly suggest you stay away from the 4140 cranks.

to add to my own response, i've read(I.E. no personal experience) that the
4340 cranks sold by Darren at DRD are really good cranks and a heck of a
deal.... 230 bucks

John...good to hear from you... never heard too much about the 4140's
longevity or performance... can you give us some insight? there were folks
on other forums that bought them and promised reports back about quality of
machinework, performance, etc... never heard back...

good information from someone with the knowledge of parts and your
experience would be great for all of us...

78 mm is as far as I can go without too much bottom end work or I would
go 80mm. I'll have to check again but the forged cranks I saw on John's
site were all around $600. I would like to explore all my options
before spending that much...

Thanks John, I must have missed the welded crank when I was looking over
your site last night. So far this sounds like my best option. I'm
building a low RPM high torque engine and I should be able to get away
with stock con-rods.

I was also looking at that torquer Web cams you carry, do they produce
more torque than a stock cam?

BTW, it's good to see you posting again. Take care.

bugpack 4340:

my recommendation is a 82mm 4340 crank with 5.4" H-beam rods. It's
easier to build than a 78 IMO.

How so? Wouldn't the case have to be releived more for the extra 4mm of
stroke?

BTW, when you posted the link to the welded type one crank on your site
I was able to see it but I can't seem to browse to it from your home
page. Any idea what am I doing wrong?
