What about regs on fuel ?

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.

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

everything else if free.

What are the regs on engines in this class ?

You should be fine with 7000 or 7500.

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.

What sort of rpm does the full spec L20b pull???

hey the rods are strong arent they??? and the 16v volvo head only fits unto the american 2300 pinto engine. that head conversion isn't all that either, cause a 2300 can achieve 300n/a hp and 760hp turbo charged.

back to the datsun talk now....cause thats the car i have now.....

D, where does one aquire a z20 or z24 series motor.
