I REALLY hate to throw something else on the dead horse,BUT,after looking at my block numbers on my RA V block,I think that any test engne sent out by the factory would be a developmental engine.They all would have been DS part numbers.My block has DS-1001,under that EO-3777 and under that*5.to the right and between those lines is 98V-400RV-05.I have never seen or had a set of 400 heads that were taped for smog.I have seen and have owned 303 heads that were tapped for smog.AND as far as I know there has only been one set of GTO exhaust found for the GTO body.This further makes me think there were NO factory installed V motors to go to the public in anyway in a GTO.If any V motor was factory installed I think it would have been a 303 WITH a smog pump and castiron exhaust.IMHO,Tom
