454 4bbl, wanting advice

[AirstreamMoho]

Hi,

I have a Chevy P30 motorhome chassis, with the 454 (7.4L) engine, 4bbl carb. Looking at ways to convert to TBI that won't break the bank.


Thanks, Derek

Use the factory 4bbl to TBI adapter, convert a 1987-1992 TBI van harness to stand alone. Finally use a marine surge tank for the EFI pump and feed it with your OEM mechanical pump and fuel system.
