I've no idea what all of that is, but damn, it sounds sexy. ;)

Porting the Kadron manifolds too? :p

CC fot CC a T1 will be more exiting than a T4, I now others may have their views on this one but the T1 will put a bigger smile on your face.
T4 head design can't flow as well as T1 head, simple as that.

Sounds like a bundle of fun engine with good reliability worked into it.
Odd size I must admit, would love to see how it runs.

This should be an interesting engine.

My first 1776 redlined at 8000rpm with stock rods and a scat c65 cam. Was fun to drive and everyone thought it was a rotary with the noise at high rpm.

Crazy rpm :shock: :shock:

Would love to modify a 1700/1800 Type 4 engine to spin so high :twisted:

Something like that. I ran a counterweighted 69mm crank with a 3kg flywheel, all balanced off course. Twin 40mm idf carbs. Ran like an absolute dream and made 70kw on the wheels in JHB.

parkarised = surface hardening
OEM = original German part

Hey cal,

How do I go about doing that? and who would be able to do it?

And what implications would this have on the push rods? Would you need to upgrade to Chro-Mo push rods or will the originals suffice??

Happy building!! :mrgreen:

for an original engine, origianl parts will work fine.

I suspect you need to go to this section of the site and do some reading...

Hey 4agedub, 3 kg flywheel, how did you get it that light was it a aly. item? Shit that is light, must have gone from 1000 to 8000rpm in the blink of an eye.
I had a FW done that looked like swiss cheese and it was 4.7 kg's not much more could be done, I think.
