Im in the process of going FI on my C5Z and im going to stick with the LS6 cam and 317 heads. Ive already got the double roller adjustable gear set, what do you guys think about advancing it 2* to have a bit more low end to combat the lowered compression with these heads. Do you think itll still rev solid to the stock limiter, or will i be cutting it to short?

this was just a random idea i had...i thought the was the blower will be spinning hard 52,XXX @ 6,700, so i thought maybe the blower would keeping it going strong up top... or would the advance kill it?

thanks guys...

 

What sort of FI are you getting? If you have a PD type blower on there I wouldn't think you'd have to worry about the low end loss of less compression.

 

-A&A V2 Si kit 3.4 pulley (pretty much maxing the blower out)
-ALKY progressive meth kit
-LS6 manifold
-1 3/4" LT's, no cats, Ti catback
