PRC 260 PTV clearance with huge solid roller cam?
Anyone got a huge cam with PRC heads 255-260 heads?
I'd get them with 67-66 cc chambers. I want to run a solid roller llsr like 244 / 257 with around 670 lift. I was planning to run ported LS3 heads and flycut but I might want to not flycut so looking at custom heads and looking for 11.0-11.2:1 compression.

Mine were 65cc. Milled them .035" to get around 60cc for 12:1
I run a 243/255 hyd. and had to flycut. |

Did you flycut much? A solid would be like 240 253 and I wouldn't mill cause I run on 91oct... Any update on your times?

I have a question for you. What’s harder fly cutting the pistons or a full cam install on a LS3 down to the oil pump?

Bo care to share which cutters you used? I've looked at the isky ones and they dont appear too have proper sizes. Unless I'm looking wrong.
