OK just started out on this got my engine together I hav a 355 with vortec heads, flat top pistons, mild cam 1.6 rockers, air gap intake, 3" oval air intake, dual exhaust with no cats. I hve seen where the 454 TBI puts out around 260 hp will the 454 TBI fit without changing fuel pump and fuel pressure regulator.

 

The 454 TB with the right injectors, should be able to handle at least twice that power if set up correctly.

The FPR is on the injector pod, pump depends on fuel demand and fuel pressure.

You will need a tune, this is the best way http://dynamicefi.com/

 

Man thanks I will do some research on it. I couldnt find a price on it. By chance would any one know the price on thid and does it come with everything I need?
