I am selling these brand spanking new patriot LS6 stage 3's because they will not fit my stock bore ls1 which i did not know at the time!! These are 4" bore, 68cc, 2.08 and 1.60 valves.
Asking $1100 Shipped OBO

 

i need these gone fellas

 

too bad they won't fit a stock ls1

 

I know that really sux!!!! but they are so beautiful!!!

 

So these will fit a 6.0? Also what springs do they have and what lift are they good to? Do you have any flow numbers?

I-2.08"/ E-1.60"
225cc Intake Runner Volume
68cc (PN - 2035) chambers

Lift 2.08" IN/1.60" EX

.100" 78 / 66

.200" 147 / 124

.300" 209 / 164

.400" 255 / 206

.500" 296 / 229

.550" 312 / 232

.600" 322 / 237

 

Why don't they fit an ls1?

 

They dont fit because the LS1 has a 3.900" bore and these heads have a 4" bore, also the valves are to big and could possibly scrap the cylinder walls. These are designed for bigger cube motors like a 408 etc.

 

Oh, Thanks
