This is sold...Heres one for you 273 guys.This is an Offenhauser Dual port intake manifold that fits the 273 engines with the earlier bolt angle. There are limited choices of intakes for thes older motors and finding one thats made to fit gets harder every day.If your not familiar with this design, it seperates the primaries and secondaries all the way to the head.The small primary ports offer good velocity to give you low end power.The secondaries are larger and they are on top so they are insulated from the engine heat giving you a good cool dense blast of air when the secondaries open up.Believe it or not these things work pretty well and they even offered some milage increases aver a stock 273 HiPo manifold.I am asking $125 plus actual shipping cost.
