Default I'm ported.

I am planning the install of my ported plenum,manifold and long tube runners. Any hints as to what I should expect installing, Any suprises that aren't in the book? After that I,m pulling the dash for restore.

Right off the top of my head, you might want to be conservative with the walls closest to where the intake mates with the head at the ports that feed #5 & 7 cylinders. I guess you didn't see my posts awhile back about me ruining my stock intake by too much porting. I will be back later with pics......


*edit* oh, wait, you already did the porting work on the intake?*edit*

My bet is that with that exhaust and ported intakd and stock FPR you will be luckey to see 800mV on the O2 sensor at WOT on a scan tool. You realy need to tune your FP.

Expect .1-.2 sec off your ET or more properly 1-2mph gain in trap speed.
