solid roller 383 dcr question I'm just about done with my iron 5.3 block based 383 ls build and im probably overthinking the wee out of this,
ok im running the comp 235-240 .646-.641 113+3 solid roller cam and if this was a hyd roller the advertised duration would be around 284-286 @ .006 which I could easily run 11.5:1 static compression and have a 8.5:1 dcr but since it's a solid it has a lash ramp and only 270 degrees at the standard .020 solid cam checking point which brings my dcr to 8.9:1 ,
I have an awesome tuner and this is a 4000lb truck engine but I have nice polished then thermally coated pistons, chambers, and valves, I will be running 92 octane, will I be ok? Thanks
