i was wondering if a 55 shot would be safe on an internally stock b18c1. other motor mods include i/h/e,ngk plugs & wires. should i have to change plugs or retard the timimg at all? what kind of times could i expect?

thanks for any help

 

you can do a 125 shot on stock internals. just watch the fuel , timing and dist to the cylinders.
it can be done though
