Re: Chevy TBI tuning help
I have had good luck on several vehicles with using the Innovate WBO2 devices, such as the MTX-L gauge and LC-2 WBO2 controller, which have an analog voltage output that can be programed to mimic the narrow band O2 signal to the ECU, but set it to do so at between 16 to 17 / 1 AFR. The leaner A/F d...

Re: Chevy TBI tuning help
Hiya Trucked, I need pictures of ECM and connectors to determine which one you have. Is the TBI from the v6 or v8? I can do the eprom chip work to get you close, nothing like being there with my emulator to dial it in 100% though. I was told by the seller the ecm and TBI are from the 4.3 engine...I...

No butchery to be seen...The seller said 350 was not modified ...So it's...

Re: First big block Chevy
Just wondering from a limited knowledge of BBC.....It's been said to use the smallest chamber with the flatest top pistons for the fastest burn...Of course port design and forced induction is a whole nother factor....

I'm one of the very few still running junk like this....two 360 degree twins, front left cylinder fires 5 degrees before the right rear .......like a big twin and the least amount of chain drive harmonics..
