Seems a lot of money for what looks like an offset ground crank and a new set of rods with basic cast pistons?

On the same note, does anyone have a reccomendation for knifedged blue/black cranks?

I have someone to do the machine work, but the added cost of having it checked and straightened makes it expensive?

Has anyone had any experiences with particular shops? (I have 3 or 4 cranks, just need the work done)

Sounds like the completely custom rods are what costs, I wonder if it makes enough difference to be worthwhile

But I'm wondering if they ARE completely custom? and if so, who makes them? (otherwise they may as well be no name backyard jobbies?)

Also wondering what the rod ratio works out like?

Chris I use a knife edged blue crank and can give you someone to talk to about getting one done.
I will talk to you about it tomorrow at the drags when I come out for a look.

Straightline Performance is Mick. He has a quick 6cyl powered blue early model ute. FJ or FX - can't recall as I usually only see the back of it

have you tried prostroke (i think that's the name)
they used to do the 235 kits based on the 221 fraurd crank

to use a stroker motor you have to use a 186 block only=234cu.

As a sidenote regarding strokers, no one going fast and winning races is using one.

What he said. :spoton:

In my opinion, you are defeating the purpose of using a counter weighted crank if you machine all the weight out of it, you may as well use a red crank.

The Rods are probably SPOOL Rods I'd guess. Prescisions sell them for about $800 a set!!

IMHO - Call Ian at Crankshaft Rebuilders in Vic and have a chat.
