    Camshaft selection for Mild 440?

    if you want high rpms cams over 5500 rpms making power why would anyone mess with a hydraulic cam anyways. Big Joe also said hydraulic cams are for sissies. lol.

    Camshaft selection for Mild 440?

    yes your right a small cam with a low lift is not going to pick up rpms. he said he wants to go stop light to stop light 4000 rpms and will never see over 4500 rpms. the stock 440 Hp cams were on a 115 LSA never turned on. I guess BIG JOE Joe Sherman two times engine master winner and David...

    Camshaft selection for Mild 440?

    not even close. comp is on a 110 LSA and 6401 is on a lazy 114 LSA. 6401 has more exhaust duration which also hurts bottom end and more advertised duration hurts bottom end and a 114 LSA hurts bottom end and the slow ramp speed of the 6401 also hurts bottom end.

    they must be good for more than 510 lift.

    Camshaft selection for Mild 440?

    high lift is good for any rpms there is no downside if your heads flow and most stock heads are good to 500 lift. on one of my 440 with stock heads and a 217-221 cam it pulls from off idle to 5200 rpms.

    Camshaft selection for Mild 440?

    yes that is why I said if I had to use it. A Hughes cam like a 220-224 cam or even a 216-220 would be better both have a lot more lift if not going to go over 5000 rpms.

    not very much lift. if I had to use it I would use 1.6 rockers.

    Camshaft selection for Mild 440?

    if you read about the 440 HP in the 67 article when it came out they talked about the small ports in the 915 heads and small valves compared to the big block Chevy heads. they said how much torque it made 480 lbs and coming in at a low 3200 rpms and peak HP at a low 4800 rpms. made a great...

    in 1967 the pin height was 1.99 and in 1968 on the piston pin height was 2.030 to make up for the 906 open chamber heads with more cc's. so yes 80-85 in 67 and 50-55 in 1969 in the hole. yes your right never what the factory said they were.

    Camshaft selection for Mild 440?

    don't want to get into a big camshaft discussion on what camshaft to use. 222-234 is almost 2 sizes bigger than stock. 12 degree spread hurts low end power compared to 4-6 degree spread. a bigger spread on exhaust will keep your power from dropping off after peak horsepower. so if your peak HP...

    yes my 67 383 was 75-80 that I measured fast with feeler gauges. what does that have to do with my quote on a 1969 440 deck height ?

    Camshaft selection for Mild 440?

    just think how good it would run with the right cam. you can always spin the tires what matters is what power it makes after that. why would you run a cam with a 12 degree spread on a 114 or 115 LSA ?

    Camshaft selection for Mild 440?

    had the crane in a 67 RT years ago in a rebuilt engine when I bought the car. stock exhaust manifolds 3.23 gears. no bottom end. it would pull somewhat in the upper rpms. it ruined the torque of the 440. stock HP cams were 212-221 duration @50. yes 10 degrees more than stock. the crane cam is on...

    the stock piston is about .051 in the hole plus .020 steel head gasket = .071. adding a .039 head gasket plus .051=.090 in the hole. does it really matter for quench if it's .071 or .090 ? I am thinking if it's more than .055 in the hole does .071 or .090 really matter ? what I heard more than...

    the stock cam has a wide LSA from the factory so if you change cams you would need more duration. keep the stock cam with the stock motor.
