  • Isky E-4 camshaft

    Hi
    I just picked up a load of 289 blocks and misc parts from an old guy who said that his dad had some quick Studebakers, well in this load was a new never used Isky e-4 full race cam kit anyone ever use one? or hear one idle? Im building a 289/4 speed combo for my 59 Lark hardtop I want a nice thumpy cam for the cruise night crowd to get confused over it being a Stude engine and not a SBC! hoping this will fit the bill

    Thanks
    Jerry

    Hey Jerry
    I,ve been running an Isky cam for years. I ended up with two of them back in the mid 80's. I can't remember the Isky number off the top of my head. They were both the same re-grind. I sent them a core and they reground it. The cam I run has a 448 lift and a 268 duration lash .018. [8D] The cam was a 2500 to 5500 rpm range. They also offered a 425 lift and a 260 duration. I put the 448/268 in a 57 289 4V out of a Silver Hawk in my 61 Lark, auto trans with 3:31 gears. The Lark ran a best time of 15.85 @ 85 mph with an auto trans that was slipping a little bit in between shifts. After a nitrous explosion that took out the rings and distorted the pistons, I put it in a rebuilt 259. It ran really strong too. I never raced the 259 at the strip but I did run it to South Bend in 88 and raced it there in the museum parking lot.
    The way I got the second was when my brother started to have an engine rebuilt for his 60 Lark wagon. I sent out a core for him to Isky for a re-grind through a local machine shop. Well he lost interest in the wagon and the rebuild while I was out of town working for a couple of years. The next time I went to the machine shop for some work to be done the guy said I still have that Isky cam on the shelf for you. Needless to say I payed for it and laughed all the way home. I didn't put the Isky in until 2002. I put it in my 64 Cruiser. The Cruiser had a 1960 259 4V in it that ran a consistant 18.25 in the 1/4 mile. Well when I put the 289 with the Isky cam in the crusier it ran a best time of 15.85 @ 89 mph. That is with an auto trans & 3:31 TT. The 289 does have flat top pistons . Other than that it has factory valves, ports, & manifolds. The same set up put in my 63 2Dr sedan ran a 15.06 @ 89mph. And yes its love with first sound with the right exhaust set up. People ask what do you have in that thing. With a four speed car set up right would be even faster.

      I got one of these E4 Stude cams in a "deal" I bought about 10 years ago. In fact, I've got the spec card that was in the box with it, right here on my desk.

      The specs are hand-written into the appropriate spaces on the card.
      Cam Lift: 283 Valve Lift: 425 Valve Lash: 015 hot.

        That's the cam I have in my 52 ragtop, and Isky E-4, a "little" bit of a rough idle, but, good pull and power.

          Ran one in a '62 GT Hawk with R3 valves in HEAVILY reworked heads and R3 headers--4 speed with 3.73 TT rear end. It was pretty quick, but the R1 4 Spd Lark was WAAAAAY faster . . .

          The E4 idled pretty smoothly--smoother than the R1 cam, actually.

              I would run that cam hard. I fell in love with mine. I don't have a lot of money. I'm on the bottom of the scale when it comes to building a performance Stude motor. Here are a couple of my secrets. Ok, no one is listening now right. Here is my secret. Be there every race day. Do all your tuning before you get to the strip. You shouldn't have to even even lift the hood unless you have a problem because its bracket racing. And remember the golden rule! DRIVE IT LIKE YOU STOLE IT!!!! Very seldom does a Stude engine ever fail. Don't be afraid to run your Stude motors hard or easy. What ever it takes to to get er done....
