fiatslug87 Posted December 30, 2010 Share Posted December 30, 2010 Wasn't one advantage of the HO the new head design? Link to comment Share on other sites More sharing options...
Geonovast Posted December 30, 2010 Share Posted December 30, 2010 Wasn't one advantage of the HO the new head design? Yes, but the HO intake ports don't line up with the Renix manifold, so you really don't gain anything. Link to comment Share on other sites More sharing options...
fiatslug87 Posted December 30, 2010 Share Posted December 30, 2010 I thought he was using all HO except for the head, my mistake. Is an HO block any different than the RENIX block? Link to comment Share on other sites More sharing options...
Geonovast Posted December 30, 2010 Share Posted December 30, 2010 I don't know if he is or not. Bore and stroke is different by a few thousandths between Renix and HO. Casting material is also different, but for the most part, they should be the same. Link to comment Share on other sites More sharing options...
mark.deady Posted December 31, 2010 Author Share Posted December 31, 2010 right now it is a full ho block with renix intake and fuel injection with distro from the renix block. the plan is to put the renix head on the ho bottom end with new cam. sorry for the confusion. and thanks for looking. mark Link to comment Share on other sites More sharing options...
