Build it!I've actually thought about using a Holley 2bbl myself on one of my builds,but I have so many things to build and so many ideas. The reason for the Holley 2bbl would be adapt it to a factory TBI manifold. I think it would be very effecient,I'm betting GM did their homework on torque and efficiency on the TBI manifold. For my 86 I've often thought, 90 Burb exhaust,700r4,stone stock TBI 350, knock sensor HEI and Holley 2BBL. I bet it would get surprising mpg and still be a good work truck
