Vortech 3.12 or 3.33
Not sure I would agree here..The full kit is designed for the 3.33 pulley..Going with the 2.87 will as a minimum take all the OEM injectors could flow while putting the engine at risk...Personally, I would get rid of the Vortech FMU/fuel pump and all the hoses that go with it and replace them with a larger fuel pump larger injectors and a RFS using the OEM rails...No more worries about A/F ratio and ease of tuning..But thats just me..Belt and suspenders...
