PRC 260 PTV clearance with huge solid roller cam? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

WHAMMO · 10-21-2019, 12:24 PM

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.

Thanks
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?

My stock heads were 64.5 cc with Manley valves.

Soo stock LS3 heads milled and what cam? Not PRC custom?

..or just a solid roller ?

Stock LS3, not milled.

I flycut the pistons .100" just because
I run pump 93 but keep timing at 24*

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?

Blakester · 01-16-2020, 10:59 PM

What fly cutters are guys using?

Bo White · 01-17-2020, 11:33 AM

Fly cutting isnt hard just time consuming

Blakester · 01-19-2020, 05:41 PM

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.

CFD · 01-19-2020, 07:55 PM

I use cutters from Lindy Tools.

Bo White · 01-20-2020, 06:14 AM
