Cruez Posted January 12, 2008 Share Posted January 12, 2008 Ok, I a possibly looking at replacing the cam in my L18 in the wagon project car, since I added the dual SU's. Now, this engine has very little mileage on the engine.. couple of thousand.. Can I safely replace the cam and reuse all the existing components?

JMortensen Posted January 12, 2008 Share Posted January 12, 2008 With the exception of the lash pads, yes. Quote Link to comment Share on other sites More sharing options...
jerryb Posted January 12, 2008 Share Posted January 12, 2008 All do respect to Jon..I have reused lash pads. Its not best practice but its done and I've never had a problem. Quote Link to comment Share on other sites More sharing options...

My point was that they'll need to be changed because of the different cam, not that they can't be reused in general. Quote Link to comment Share on other sites More sharing options...
TimZ Posted January 12, 2008 Share Posted January 12, 2008 All do respect to Jon..I have reused lash pads. Its not best practice but its done and I've never had a problem. I'm pretty sure Jon knows that - I believe he's saying that if your new cam's base circle is different you will need lash pads that keep the wipe pattern on the rocker pad. It might work out that you can re-use, it might not, but you should NOT assume re-use without checking first. Quote Link to comment Share on other sites More sharing options...

Cruez Posted January 13, 2008 Author Share Posted January 13, 2008 Thanks for the info guys, I'll check the wipe pattern... Since putting the the Twin SU's and opening the head a little, I think a upgraded cam should help the little L18 quite a bit. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted January 13, 2008 Share Posted January 13, 2008 The one thing I don't like about the twin SU's is the tiny air cleaners. They seem very restrictive. I wonder if the Z K&N's might fit. They would fit if you bolted up Z SU's. Had a friend do that years back. Ported the crap out of the manifold and the head and ran an L20B off of Z SU's. Worked pretty good too! Quote Link to comment Share on other sites More sharing options...
Tony D Posted January 14, 2008 Share Posted January 14, 2008 The stock air cleaner (if you have it, or can fit it in a LHD car) works pretty well, and K&N does have a filter to use with it. Also, using a stock 240/260Z replacement K&N filter sandwiched between a couple of aluminum plates makes for a NICE SSS SU Aircleaner Setup. (Think like the early roadster air cleaners. A beadroller and sheetmetal can look damn stock sometimes!) I'm helping my son put the very same setup on his 70 510 Wagon, and this is the same spot we are at...which aircleaner do we want to run? I don't like the small units either, and having to remove the entire intake to access the aircleaner element is a royal PITA. If I wasn't so hardheaded on making the boy live with points and carburettors for a couple of years before moving into EFI this would be SOOOOO much easier!

Cruez Posted January 14, 2008 Author Share Posted January 14, 2008 I have the "rare" SSS type air cleaner... If you decide that you want to run this one... its a VERY tight fit on a LHD car.. I have about 1/4" from the master cylinder.. I'll be able to tell better when I get the tranny installed. I could half the bakelite insulators and gain a little more...
