Nice!!! Now pull the frisbe, set the initial timg to 8 degrees, cut the airlid, K and N filter, de-screen the mass air meter,add underdrive pulleys and add full synthetic oils. It will still look and sound bone stock, but you'll be amazed!!!

Sounds about right to me. That's just about where I expect an 89 ZF to land. You might have 10hp/10tq still left in the tank if everything's not completely tuned up.

If you do move it, it is less of a blockage for the path of airflow in the plenum

Pull the frisbee, install March #4425 U D pulleys, cut the air lid, remove the precats if you can. Go to dual outlet OEM style mufflers. Pickup @ 30 more HP.

IAT isnt used except for EGR on MAF systems...
1.6 rockers showed a decent gain on my L98. I was in the 230whp range with exhaust bolt ons and then with stealth ram/1.6 rockers i jumped to 254whp/315wtq but was running abit lean. Probably had 260/325 or so in it.
