Thinking about my plans for the LT1 intake. Yeah it will gain me some RPMs and hp up there, but the loss of torque is looking too great. Here are Dyno numbers from the Popular Hotrodding article: If I had similar results, I think I would be angry. I'm not sure why I thought the LT1 intake was a good idea, looking at these results. So here is my thought, what about a "custom" intake? Say taking a low rise single plane and drilling it for injectors, slap a 454 Throttle body(minus the injectors of course) on top of it and call it good. Now that is where the sensor question comes in. Do you guys think the TPS and IAC(bigger of the two hurdles I bet) would be compatible? TPS sensor, as long as the wiring is the same, I can't see an issue(and even then repinning a connector so it is the same, not difficult). Also, would this be enough airflow for a TPI motor? I think 454 is something like 650 with the injectors, so figure like 680 maybe... I think stock TPI is what, 700? A Holley 4bbl throttle body would be nice, but $$$ Mainly my goal is to make RPMs with a TPI setup and still have torque. I'm not saying, the exact same torque as the stock TPI setup, but not 50ft-lbs less.
