I've decided (aka been wishy washy) on what to do with my 2 trucks. I'm going to focus on tearing apart my F250 and going through it in the best body on rebuild as possible. In the mean time, I'll need a truck to do my weekly truck duties, so I'm going to give the 460 more love. So far I've rebuilt the carb and bumped ignition timing into the 12-14 BTDC range. It is chuffing out the exhaust, and the old dollar bill trick tells me that it has a burnt valve or two. So I'm pulling the heads this weekend and will have them sent out. I have a gasket kit ordered up, along with a straight up timing set. I'm thinking about getting a mild (and cheap) cam since I will have this thing apart anyways. Summit sells this K3500 cam with the following specs: Basic Operating RPM Range:1,200-5,000 Intake Duration at 050 inch Lift:204 Exhaust Duration at 050 inch Lift:214 Duration at 050 inch Lift:204 int./214 exh. Advertised Intake Duration:282 Advertised Exhaust Duration:292 Advertised Duration:282 int./292 exh. Intake Valve Lift with Factory Rocker Arm Ratio:0.486 in. Exhaust Valve Lift with Factory Rocker Arm Ratio:0.512 in. Valve Lift with Factory Rocker Arm Ratio:0.486 int./0.512 exh. Lobe Separation (degrees):112 After the heads are gone through I'm thinking I'll try my hand at giving them a mild port job. This motor is extremely low compression, so its never going to be a tire fryer, but that's alright. I'm going to ditch the air injection system, and delete the EGR functionality as well. If anybody has any suggestions on cam's for this build I'm open to hearing. Low RPM, high idle vacuum is what I would like.
