Have decided to go with hyd flat tappet cam because i allready have all the valvetrain parts for that, what you think about comp xe274 0.050 230/236, lobe 110. It is almost identical to the old merc 454 440hp cyclone cam. My heads flow better than those cyclones and i have 10 to 1 compression against the cyclones 8.5 to 1. My dynamic compression would be 8.37 with the xe274. Hoping to get in 470-500hp.

what your trying to do,,you can use the timing cover(need to drill and tap for extra bolt holes) and for the pan,you need to get a gen5 oil pan.cam may need a shim up by the gear to align chain and need a cam button.prety sure thats what I did on my gen 6 blocks.its been since 2004 when I did it.
