I may or may not have posted this previously but in any case I am the current owner of ELVA MKIV/86L, having purchased it from Tom Grudovich in approximately 2012. It was powered by an FWE when I bought it and now has an FWB (1460). I race it frequently in eastern-US vintage events with good results.
From what I know the "L" in the serial number refers to "Long" and reportedly there are four additional inches between the firewalls than in non-L cars. The cockpit is certainly roomy but I merely seek verification of this fact (if it is a fact).
I also wish to announce that I have a full set of high-quality MK IV body molds and if any MK IV owner needs replacement body parts please make contact at:
michael.oritt@gmail.com. They are
NOT available for the building up of a "new" car--only for repairing an existing and original IV.
