I'm Awesome
As stated earlier although I used Hooker long tubes, the 94 G10 with the 305 TBI was making 15 ft/lbs more torque and only 7 hp less than my L31 350 made stock. Headers, dual inlet cat, 3" single exhaust with a Magnaflow. The TBI stock exhaust especially with the pellet cat was a cork to any resemblence of power.IMHO, shorty headers alone may add some TQ/HP but, in conjunction with other free flowing components you'll see a marked improvement. Things like a mandrel bent Y pipe, which helps in scavenging, to a 3" High Flow CAT, especially as apposed to the OE pellet ones, and a 3" straight through muffler, like the Borla Pro XS. YMMV
This 87 is like someone added a small shot of nitrous now compared to even the Hooker manifolds.
