Re: Low rpm 390 stroker advice

I don’t want to get too specific because Brent lykins custom sized it for me in order to stay with stock transmission. It pretty much follows what him and Ross have suggested in other threads. I don’t think he would be too upset for giving conceptual info and not the specific lobes or numbers...
Around 220 degrees intake duration at .05 lift,
a small split between intake and exhaust to help with scavenging,
under .5” total lift,
more overlap than 110 lsa,
and enough initial timing to almost worry about hitting valves.
The idea was to get close to the Comp XE262H but without slamming valves open and closed, without the valvetrain noise, and with more overlap and with more timing
