Are these are good alternative to a new cam and new rockers. I'm looking at doing this with an L series cam and rockers, has anyone had experience with re-ground cams and re-surfaced rockers on an L series engine, or re-ground cams and re-surfaced rockers in general ?

I've used a wide range of L6 re-ground cams (Wade and Crow for example) as well as re-ground rockers to match (Wade) and never had a problem.
Getting the geometry right is absolutely essential in any L6 engine, and this can get expensive given the added cost of lash pads.
A new cam + rockers is going to be pretty exy, and not really worth it, IMHO. -
Kalium, have you got the book How to Hotrod & Race Your Datsun, Bob Waar, Steve Smiths Autosports Publication? It has heaps On the L series boat anc.., errr, engines.
Tarting up L series engines can get very expensive, as lambs indicated. You are doing a turbo aren't you. Just get the basics right and you will have a quick car anyway, IMHO.Richard's DatsunZ lappin LakesidZ http://www.youtube.com/watch?v=47OSh...&feature=g-upl

OK, Alan Stean from the Zcar workshop may have something or check with John Siddons on the Gold Coast. Do you know of John? It is just that I have seen people throw money at L series engines with little result, which is not to say that you cannot get reasonable power at a reasonable price from them.Richard's DatsunZ lappin LakesidZ http://www.youtube.com/watch?v=47OSh...&feature=g-upl

No I haven't heard of John, do you have any contact details ?
Im planning on not throwing any more than $1000 at the engine (that includes a rebuild), and I'm doing all of the work myself.
Not sure if I posted the planned mods somewhere else, but this is what Im in the process of doing
Flattop pistons (10:1)
New Fuel rail
Injectors
RB30 ECU
70mm MAF sensor
64mm TB
2.5inch exhaust
valve job
re-ground cam
slight work on the ports
...and thats about it I think

Don't suppose that JS would mind the publication of 5537 4977 as the phone number for his Gold Coast car mechanical repair business. Maybe mates rates
