Try this one, although I think it is a fax back setup, although I might be wrong!

I thought that was going to be Sarsh's engine...
Need more details before I can help you choose a cam... Give me the specs on everything:
Cyl head type,
Inlet and exhaust valve sizes
Compression ratio
Intake manifold
Carburettor
Exhaust
RPM range
Auto/Manual
Diff ratio
Vehicle weight
Fuel type
Intended use
Roller Rockers?
Valve springs?

I have a 186 (now) just finished rebuilding it, have got some hardcore internals and find that "Precision Dynotec XU-1" Cam is perfectly what you have described. Im using it in mine and it lumps over at idle, revs nicely and still drives as if you were running a standard cam (very smooth power delivery).
Ive only got 150kms on the new motor, so i havent flogged it yet (been up to 4000rpm, but no higher), but it likes to rev - it wanted more revs than what i was brave enough to give it!
I fly home from work on thursday night - ill jump on MSN messenger and send you a video clip with sound of mine running! It sounds awesome!

Looks like i need to sort the cam out last
here my list so far, not finished though
186 block
60 thou pistons flat top
Starfire rods
JP straight cut timing gears (JP 5994)
Harmonic balancer
Big end bearings Size:
Crank bearings Size:
Cam bearings Size:

Head will be a yella terra (no info on it yet) but i do want a very good highcomp one
ill have to build this engine then decide on the cam
but i do want a very tough engine for street use, even if its a bitch in peak hour traffic.
thanx guys.

For the record, in the Crow selection the 35604 is the XU1 grind, and 35616 is the 'Bathurst' XU1 spec. Both for 202s.
I'd go with 1QUICKLJ's recommendation of a 35802, you'll also need:
4823 valve springs
11707 retainers
11703 collets
I'd recommend R/Rockers Street Terras will be fine, and also get some decent pushrods, Crow part# PR9515.
Let me know if you need any of them.

i wasnted something a bit bigger, but not a cam that woudlnt kick in untill like 300rpm, as i wont be thrashing the motor! its just a nice daily!
Although a lumpy idle would be nice !
