Question about adding a cam, headers, and intake Hi there recently I dropped a freshly rebuilt 1992 350 TBI with a roller cam into my car, I added an open element intake and headman headers and removed the cat. I was wondering roughly how much horsepower and torque id be pushing? A couple buddies have asked me and I don't even have a rough estimate. Any answers are much appreciated |
Re: Question about adding a cam, headers, and intake What did you do ECM tuning wise? What the the specs of the cam? Without chip tuning, you're going to be leaving a ton of power off the table. |
Re: Question about adding a cam, headers, and intake Dyno it, without any specs it’s hard to say if it’s 190hp or what. |

What heads? Also the ECM in it now is from the old 5.0 the car had originally |
Re: Question about adding a cam, headers, and intake Several ways to tackle the tuning. A wideband gauge is a good investment to see how it’s running. or do a plug read. If lean might want to get larger injectors from a 350 truck. ANLU or ATJP prom chip if automatic. Or instead of doing chips and refining the tune dynamic efi has the ebl. |

Re: Question about adding a cam, headers, and intake eBay, junk yard get a burned copy. There plug and play was used on 89 caprice 350 tbi same ecm though. hard to say how it’s running now but might be worth experimenting. |
