    Do you know the size of the valve. Did you have any issues with the length and did they also use the matching guides.

  2. I did know at one time but it has been a couple of years so I would not trust the "old" memory as to the specs. You could give Dave a pm or I can contact him if you don't get a response.

    I'm also looking for info on a cam. What's a good grind. Who carries new blanks.

  4. Tony has new cams and can offer ideas on grinds for your particular application. Paul may chime in here as he has had Delta regrind some cams for him on a few of his builds.

    I have a set of adjustable rockers that I pulled off an Olds 303, is there a way to check what ratio they are by measuring?

    Is this the the measurement you're referring to or are you just playing hard to get?

    On my 1.8s the shaft has a clearance notch for the large bolt.

    yes of course a rocker ratio can be measured.

    divide the distance from the center of shaft bore to valve tip contact patch by the distance from center of shaft bore to center of push rod cup.

    One thing to consider. There's lots of reports about guys breaking old school 1.8 adjustable rockers, my hunch is this is down to running them on modern cam lobes with aggressive hydraulic intensity numbers. I haven't cam doctored my E-3, but I have cam doctored an E-2, it had a hydraulic intensity number of 48. That's pretty gentle by modern standards, For comparison, the modern Comp Cam lobe in my truck has a hydraulic intensity number of 32, and the most aggressive flat tappet lobes can be down in the high 20's.

    I'm not sure I would even bother running them, I was mostly just curious. If needed I'll buy a set of adjustable pushrods and use my stock rocker arms. I still need to strip the motor and send the block out to the machine shop to see if it's salvageable. I turns halfway then gets stuck. I've had the heads and pan off and cleaned out some of the rust that was in the cylinders but it still needs a little persuading. Thing might be a boat anchor.

    Here's a couple pictures. Pretty grimy still but you get the idea.

  18. those headers look like Belond from CA. Looks like they may have been modified a bit. Still a nice find. Just sold my NOS ones to Jim (fedcospeed) for his Olds build.

    I believe you are correct, although I think only the left side has been modified. These belong to a friend of mine, he bought them at a swap meet years ago and isn't willing to part with them.

  20. yes, the ds has had the 3 bolt flange removed. PS looks stock. Sandy Belond and his Equalflow product was bought out by some guy named Hedman!

    A few months back I paid 400 for a 55, 324, primarily for the heads and rocker assy. I know the #10 heads are the most sought after ,but with putting new hardend seats in I figured I'd also put in the bigger exhaust valves. With this motor I was also given a offy 3-2 manifold, a stock 4 barrel, and stock 2 barrel intake. I'm letting you know that I'm looking to get rid of all the leftover parts. That includes the intakes, crank, rods, timing chain cover, block, ect, ect. This stuff takes up too much space and is too heavy to keep moving around. So if your needing any missing part pm me and I know we can work something out. I'm not posting this to make a quick buck but to let you know that I have parts available.

    Glad I found this, I have a Hilborn FI unit that has 303 stamped on it. Anyone ever seen a Hilborn unit for this engine?

    My Gotha adjustables are still operating the valves quite nicely. #10 heads. Valve springs are 440Dodge. Crane hydraulic lifters. TRW 3/4 Full race camshaft.
    By The Way: if any of you know the catalog specs of this camshaft, I would appreciate hearing from you.

    Sorry for bringing an old thread back from the deal. But I have a 1956 Rocket 88 motor in my Ford Tudor, and am in dire need of an oil pan. I can't seem to find one anywhere. Does anybody know what year Olds oil pans will work with my 1956 324ci? Thank you!
