Thread: 302 Stroker??

Tweet

You might call Mallory and give them the height dimension from hold down ring to top of manifold and see if they have a tall drive with the skinny top that fits? If you can get a technician over 40 you might have a chance....

Looking back, one photo in your Post #21 on Page 2 (Link Here - 302 Stroker?? ) shows a distributor in place?

That MSD Billet I gave you info about wont fit? Not sure if there IS a smaller diameter distributor with that one being 5/8" less then a stocker.

Roger - don't you mean over 50

Roger. That pic with the distributor is the closest I've found so far and that one still needs to go down another quarter inch.

Dave, since the measurement you provided was still in excess of 3" I figured I'd keep looking. You taking yours out??? Can I borrow it for a trial fit??

I'm thinking I'll have to call Summit and hopefully get a tech who won't mind digging into some boxes with a tape measure...

Let me know the next time you are coming this way - we can probably work something out -

HMmm.. I'm wondering what you're really saying? LOL... I was just in New York this week. Town of Hillburn. Right next to Mahwah, NJ.
I might get back out there in 4 to 6 weeks. I'll PM if / when it happens. TIA

That's the wrong direction from Schenectady/Saratoga area - but detours have been know to happen .........

Mike,
The Mallory Billet Comp on mine looks to be just a hair under 3" OD below the cap. The ledge on the cap makes it 3.25" but that should be well above your manifold. I really think you'll have a lot better luck calling Mallory or MSD direct and talking to their tech guys instead of Summit. There's gotta be a distributor out there that fits. They used the manifold back in the 60's, right? Maybe a magneto.....

Roger, could I trouble you for a pic or two? Measurements?

Sure, but it will be Tuesday/Wednesday before I'm back where I can get it for you.

I'm nothing if not the picture of patience!

On the dist issue-----look for a mech advance only one as they aren't as deep as the dual advance ones----so there is more height from the mounting flange part to the bottom of the main where the advance and points are----------

Thanks for the tip! And here I thought only the same 3 or 4 guys ever checked this thread....

Read my lips-----the centrifugal only advance distributors have smaller bottom housings and will clear that manifold------

I think you're right...

The distributor that is shown in the pics is a centrifugal only advance, it's close but, just not quite there..

So this talk got me thinking (may be dangerous ) that in my old days I never messed with a distributor that didn't have vacuum advance, and now everything I mess with is total electronic/computer controlled. As I'm thinking about it, the mechanical advance can be adjusted, via springs & weights, to yield the slope you want and the rpm where curve starts climbing but you've got one curve of advance vs rpm which means the advance at say 2500rpm is what it is, whether WOT or 1/4 Throttle. Adding the vacuum advance lets you overlay a second advance curve for part throttle operation, which lets you pull in a few degrees at cruise for improved economy, right? The ECU controlled spark goes a step further, allowing the spark to be mapped over rpm and vacuum independently to create a "topo map" of timing. So if you run a distributor with mechanical advance only you set your advance curve for WOT operation, and then tune the carbs to get the best economy you can? Are there any "tricks" for weights and springs to change the shape of the curve to get closer to optimum? Guess this is why the old shops had the Sun machines with O-scopes, right? Just curious, and not trying to get too far off the path here....
