Combo is standard bore 350cid.Older style B&M 142 blower (restripped/bearings etc).Dart Pro 1,s 200 cc intake runners,(2.02x1.60) (unported) but matched to blower intake.Camshaft is Comp special order,ADV DUR.intake 274,exhaust 282.Dur.@ .050 is 224 intake/230 exhaust.Valve lift.is,intake .538,exhaust .534. Lobe sep is 115. This is a hydralic roller.Also running comp ultra gold 1.6 roller rockers to up the lift to roughly .565/.560.or thereabout.750 cfm holley.I,m thinking or hoping that this combo will be a torquey little small block.It ran 11.60 @115 with .435"/.460"/212/222 duration flat tappet cam in 69 camaro @ 3470#. How much torque and horsepower should I pick up changing to a roller setup.Thanks
