How long do you want it to last ?


A full racing season.......which will be no more than about 20-24 hrs, all out.

And once in a while a regular drive on weekends.

i asked that question because the rod ratio of that engine is really low. 1.5 or sumtin so.

engines from 1800cc to 2000cc? Standard cylinder blocks must be used(i.e no aftermarket alloy blocks etc)

everything else if free.

was cleaning and found some 35mm exhaust valves i had 4 my fiat TC engine but they are 4.25" compared to the Lseries 4.57" in lenght.

Is there anyway i can get these to work in the Lseries head.

ps.They fit into the valve quides correctly too.
