    How much good are Tri-Ys with my set up?

    I had a nice face-to-face talk with the tech guy at CP Pistons about 331 vs 347. He said that most guys run into trouble when installing the ring support on the oil ring land. It gets tweeked and then the ring looses some of its oil sealing properties. If installed expertly, he said that the 347...

    How much good are Tri-Ys with my set up?

    Your 289 requires 1 1/2" primaries, max, for best performance. A stroker will need 1 5/8" or 1 3/4" primaries - assuming street use. Well-made tri-ys make mid-range power and often good high-end power. This seems to be due to the short primary tube, especially if the secondary tube is large. If...

    Need cam opinions please

    Yeah, but the optimal LSA for peak power does not produce the flattest power curve. They tend to be more peaky. Fine for a race motor with a limited RPM band, but street cars benefit from flat power curves. I think thats why many engine builders use a wider LSA than what would produce max. peak...

    Valve clatter could it be timing?

    0.060" is the largest gap recommended by MSD. They recommend 0.050" - 0.060" for up to 10.5:1 compression. I use a different capacitive discharge box, but similar. My gaps were at .050". When I took it to be dyno'd, the top tuner there told me to take them down to 0.040". I only had a few...

    If you had...

    Yeah, there is very little, if any, difference between the 289 and 302 cylinder bores in terms of length. A 302 is cheap because you can find a used rotating assembly easy - there are a lots of these around from guys who stroked their 302s to 331/347. Crank and rods will cost next to nothing...

    What size Radiator will I Need?

    The stock battery support/tray is held in with 2-3 fasteners - not welded in place. Mine was pretty corroded and I replaced last year, so I remember. If yours is welded in, it's not standard.

    What size Radiator will I Need?

    Look, you need a radiator the same height (or VERY close) to what you now have. Measure it. Going to a larger rad without cutting (widening) your radiator opening isn't going to do too much (going to a good aluminum one will, however). So, figure out how much you are going to cut and see how...

    Need cam opinions please

    I believe he is running Edelbrock Performer or Performer RPM heads. That's why I put the hp est. above 325hp. There is also a lot of split in the cam duration, which usually helps make hp at a slightly higher RPM, also helping peak numbers (if not overdone and killing backpressure).

    Valve clatter could it be timing?

    Also, according to your earlier post your plugs are gapped to .060". That is way to much gap. Close them down to .035 - .040". Your ignition is going to have trouble making good spark with that gap. I'm not surprised that is has trouble firing as RPMs climb. Try this and and see if it helps.

    T-5 Spacer

    No, you do not need the spacer for the fork if you use the T-5 bell and one of the cable clutch conversions. There are several and each has its proponents/detractors. The Modern Driveline cable works well, but replacement cables are pricey. MustangSteve's works well, also, according to some...

    Need cam opinions please

    You'll have a 306ci motor. That cam will lope some, but it won't be bad. I would think that you will be in the 325-350hp range. Should be fun.

    What size motor? 302/331/347 ... I don't remember. Flat tappet cam, right?

    460 in a 67

    Let's keep in mind that the Boss 429 had hemi heads and they were much bigger than CJ heads. A CJ/460 should be easier to fit than the Boss.

    Iskwezm's turbo kit

    With 60cc heads (Edelbrocks) and .005" piston-to-deck, a 16cc dish should bring it down to about 9.3:1, by my calculation. He'd have to open up the combustion chambers to get it lower - and it ain't a bad idea to lay back the chamber walls a bit to unshroud the valves ... but then that's NA...

    If you had...

    Yeah, forget the Vic jr heads unless you stroke the motor to at least 331. They are too big, in my opinion, and you will end up with sluggish performance under 3-4K RPM. Twisted Wedge heads would be much better if you stroke it even to just a 302, which is uber cheap. If you do...

    289/302 Questions

    My advice is to use the marker that is there and re-mark your balancer. You want to find TDC, compression stroke, which isn't too hard, and then use a timing tape (Mr. Gasket has them) to correctly mark the balancer. To find TDC, remove cap from distributor, turn engine until the rotor points...
