I Hate Porting Heads!!

Yeah, I already thought about the VG's but I figured enough was enough for this particular build. It's Jeep 4.0 HO I6 with MPFI (that explains the weird bump in the top of the intake port for the injector). It's really limited to about 5200 rpm anyway and my biggest concern was low lift flow. It's rated at 190 from the factory but I'd be thrilled to see 210 to 220.

yea u could get those numbers easily if u have the parts. when me and an "old timer" friend built my SL6 taught me alot! so now with a heavily ported head and a .510 cam... endless list! after some break in miles we put it on the chassis dyno for some light pulls. it was running lean on the primaries and only spun it to 5K and it pulled 180hp and 240tq! my compression isn't where i want it (9.2:1 vs 10:1) and im looking at 1.6 rockers(340 lobe, ~1.35 stock rockers=.459 vs 1.6 rollers~.544!).

so im trying to get a SL6 to 300hp as a daily driver! i get 18mpg right now!
