Good Morning all!
So I have gotten over the funk that beset me last year and I am going to
make the go-fast engine work.
At this point I would like any info or suggestions on rocker setups to use.
The engine builder used the stock early cast rockers and cross drilled
adjusters. I would like something better. Much better. And reliable.
Thanks,
Lester
Supposedly for a 1380 engine

And where would one purchase a decent roller rocker setup?
Thanks,
Lester

I can dig up the specs if you need but I must say I will NOT be able to use the
1.7:1 rockers due to spring bind. The valves open too wide and compress coils
of the valve springs against themselves. I am using heavy springs. I am not
sure what I will do about this. I hope a switch to a 1.5:1 ratio rocker will
cure the trouble. I will be putting this engine in my sprite with a 4.55:1
differential and a Datsun 5 speed gearbox.

got them through Mini Spares.

This is where I am now! After spending the money for a go-fast setup?
