I am setting up my L18 with twin 40 dellortos I am match porting the head to the manifold . Can any one tell me what lift cam would be best for this setup .

Try Wade Cams in melbourne, i'll find the link for you. I found them really helpful.

There is another mob in ferntree gully. A couple of blokes who left Wade. The old school guys. Clive Cams. I don't know the number though. They are the guys who will do My cam.

Also Crow Cams do new cams to suit from blanks.

Fcty 4/ 35 -37 Clyde St Ferntree Gully 3156
clive is your man he does our a12 racecar cams
and my mates 372/410 sprintcar
LOTS of knowledge

Definatly use a Wade cam. They do a works 72 cam that is great for a hot street l series. Good strong power from 4000 through to 7000. This is probably the hottest cam you want on the street. Think the identification tag is M12.
Crow cams are best left for two stroke lawnmowers not l series

thanks fellas for the advice Ill do a bit of homework on it

You can add Tighe cams to your list too if you like.

Good work Dodgy on the link,this is why i prefer using Tighe,Dean requires ALL the information before he will reccomend a grind,and is yet to fail me.He also competes on a regular basis,as does Ivan,but he's semi retired and they both share the passion especially with older four cylinder stuff.
