I have a 250 and need to know what the length of the pushrod is? Will the FE engine pushrods interchange?
Thanks,
Ken

I went to Summit Racing today and bought a set of CompCams pushrods, P/N CCA-7533-16. The fit perfectly. They are for 332-428 FE, with adjustable rockers. Tomorrow, I should get this 250 running.

Head was milled .060. I think there is enough adjustment left in the rockers to add a little machining to the deck.

Just so you have the info...
200 pushrods are 8 5/16 inches long.
250 pushrods are 9 5/16 inches long.
.060 shorter pushrods were offered by Ford back when - good luck finding them now. Pioneer Perf. Products offers pushrods in +.060" and in -.060"
Mike at FSPP has chrome moly pushrods, but I'm not 100% positive he has them for the 250.
Ken thanks for the info on the 332-428 FE pushrods. I'd like to know their length. Actually I'd bet we'd ALL like to know. It would seem to me that they would have different lenghts for the different blocks. Anyway, I just like to learn new stuff!

Dennis,
I am on the road now, when I get home, I'll measure them and let you know.

Dennis,
I did a quick search and here is you anwser:
FE Hyd Push Rod 9.595 Stock Length Non-Adjustable Rocker
FE Solid Lifter Push Rod For Adjustable Rocker (Std Lgth) 9.157" (= Comp Cams 7533-16)
I know (from your book) the 250 pushrods are 9.3125. I had the head milled .060 and subtracted .060 from the lenght that gave me 9.2525. I found these at 9.157. I know there is enough adjustment in the rockers to make up the difference.
I hope this helps. Also, Mikes prices are much better, I paid 102.60 including taxes.

So Dennis,
What are your feelings on these pushrods? You know volumes more about this engine then I do.
Thanks,
Ken

We've found (Aussies/Kiwis) that the tubular ones are likely to suffer problems, not the solids. 250's tend to vibrate quite a lot more than the little 200's
Over here, talking X-flows, there was a case when the earlier cast pushrods would hack almost any revs, but the post 1980 ones were dreadfull past 5000 rpm. Anyone doing a back to back comparison with a 200 and then the 250 notices the difference in smoothness. Its sort of like comparing a good 289W to a 351W, the little one is smooth, the big one is a bit of a savage animal, not any extra power, but a lot more torque.
Our 200 cube X-flows ran the same rods as the 250, but even on the smoother 200, at 5500 rpm, the pushrods could still break.
I had my old X-flow with tubr rods up to 5300 rpm and never broke them, but the aftermarket cam profile was pretty soft at 256 degrees.

Ken,
I called my brother to ask him about the 250 pushrods (he has a 250 in his '65 Ranchero). He is off in his motorhome and will measure the pushrods soon.
Here's what is hard to know about the length. David measured from top of the cup to the bottom of the ball. Does Crane measure the same way - or do they go from the BOTTOM of the cup to the bottom of the ball? - which would be the actual lenght?
If you take 9.157 and add the milling of .060 = 9.217 and IF the measurement is from the bottom of the cup add APPROXIMATELY .100 for the difference of the measuring technique then you have 9.317 compared to stock 9.31 and EUREKA!
Stock Ford Pushrods are solid.
I don't think Crane is going to sell very many FLEXING pushrods at a $100 a set.
I think the lightness of the tubular pushrods is a bonus - If your goal is 5500 rpm - you'll get there by having less weight in the valve train OR much stronger valve springs (which will put more stress on the cam lobes and pushrods. IMHO, I like less weight and moderate valve springs.
I found xctasy's comments very interesting. Granted - 250's do not rev as fast as a 200. They are not as smooth (however balancing solves a lot).
Granted "post 1980 ones were dreadfull past 5000 rpm." I don't know squat about Aussie sixes, but it seems to me that Crane makes a better product than Ford.
So a lot of us are waiting for these puppies to show up at you door and for you to weigh and measure a stock pushrod and the Crane pushrod.
If FE push rods are going to work, you'll be the pioneer blazing the path.

Hey wsa111,
The pushrod is a solid pushrod. The FE's have a real problem with there valve train's.
I will get a measurement of the pushrod when I get home.
