Re: 69 marcos lead vs. unleaded

2002-11-10 by Don Lattimer

Hal,

We haven't had leaded gas in California for many many years!  I 
drove my Jensen-Healey for 120K miles on the unleaded with no 
problems.  I've put 14K or so on the Marcos (V6) and just use 
unleaded with no additives.  There has been a lot of discussion over 
the years about conversion from leaded to unleaded valves, etc.  
Both pros and cons.  If I ever have to rebuild the engine I'll 
convert then.

The US shocks are HAL shocks.  www.halshocks.com They aren't cheap 
either.  Can be purchased thru HAL or Summit Racing.  Dave Barton 
has purchased HAL shocks for his.  The problem I found was that they 
are 2 1/2" ID springs vs. the 2.25" springs.  The 2.5" springs 
wouldn't fit my rear shock mounts without modification.  They have a 
few different kinds so don't get confused.  One type of coil-overs 
has soft compression (for hot rods).  Let me know if you need help 
with them.  I talked to the HAL folks and did a lot of research.

Hope the schematics helped.

Hurry up with those pics!!
