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.

You should be fine with 7000 or 7500.

What are the regs on engines in this class ?

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.

What about regs on fuel ?

anything goes really......dont think u can use methanol tho.

Anymore tips/trick on tuning this engine????

l20 block, z24rods, z20pistons, l20 head ported valves double valvesprings cam depends on valve sizes. twin 48 or mechanical injection
cant go wrong
