Why re-use chain when there cheap i was going to go with gear drive.

Just curious at what your combo is (if you don't mind me asking)
Real performance will be gained from the heads...TFS are good but AFR's are better...Canfield, Pro-TopLine (now RHS Cylone) and Darts will all make big power...to get an honest 500hp and
streetable from only 351ci's you should go to a Roller Cam (you have one...what brand??)...Ed Curtis (FlowTech Induction cams), Jay Allen (Camshaft Innovation) and Bill Metzger (Lazer cams) have cams that would put you deep into the 11's on motor...I have used Comp/Crane/Crower...with good results but have run the fastest with Lazer cams
As well, I wouldn't run a gear drive...harmonics (vibrations) are transmitted to the valve train...stay with a double roller...a Belt drive is the best
