Shouldn't need a dual taper on the 11/32 though correct? I understand on the 3/8's. I was running 5/16 .120 pushrods with the last rockers. In a pinch I got some 5/16 .080 pushrods, but they ended up being too long. I think these 11/32 will work out nicely. Especially considering the mild spring pressure of the BTR 660 kit.

 

I could've done that, but I didn't have either of my calipers with me. (I recently moved). I had enough for 1 full turn down on the Jesels, but couldn't fit the pushrod with them backed all the way off. I knew it wouldn't be exact, but I wasn't expecting it to be off as much as it was. Oh well. Next time I'll make the 1 1/2 hour drive to pick up my remaining tools just to be sure.

 

Screw making the wires. Measure the lengths and give firecore50 a call.

 

For a 3/8" pushrod, it has to be a dual taper? A single taper won't work?

 

Lol. Never again. Never.

 

11/32 should have no issues, it's the 3/8" straight wall comment I was referring to with my post. My apologizes, I should of quoted his post before confusing you.

 

I've had instances where a single taper would work, and where it wouldn't work.

It seems core shift makes it hard to determine this before hand, so I always go with a dual taper for good measure.

 

Stay away from 5/16 for this, just be enetering a world of pain other wise.

I'd go 3/8 dual taper 80 thou as a minimum, ideally 100+

 

It's ok. I was pretty sure that's what you were referring to. I just wanted to make sure you didn't have any issued with 11/32 pushrods.

 

Would the Manton Series 5, PN 515-145 3/8>11/32 dual taper .145 wall be overkill for this @$29? I'm hoping yes due to the cost... $500 in pushrods seems excessive What's a good compromise between cost & tensile strength?

What sort of tips do you need to mate with Morel lifters and the Jesesl/T&D rockers?

Call tick and get a set of their trend dual tapers. Half the price of those Mantons.

 

5 series isn't needed for this. 3 series is just fine if you like Manton.

We sell 3/8" dual taper 5/16" .135" wall Trends for 250.00 shipped.

No special tips are needed, but tool steel is a good option for a stronger tip.

 

Taken from vettenuts on corvetteforum:
This is vs. a 5/16" .080" pushrod

11/32”, 0.120” wall: 59% greater
3/8”, 0.080” wall: 92% greater
3/8”, 0.135” wall: 122% greater
3/8”-5/16”, 0.080” wall, double tapered: 72% greater
3/8”-5/16”, 0.135” wall, double tapered: 97% greater

It really depends on spring pressure and cam really. I'm only running around 400lbs of spring open, and my lash is around .007 hot. You always want to run the biggest pushrod you can. The bigger the pushrod, the better the load spread.

I wasn't very worried with my setup and the 5/16 .120. I was however a little concerned about running the 5/16 .080, albeit that was temporary. From vettenuts calculation, you can see how much better it is jumping up to just a 11/32 pushrod. Clearly for us, the 3/8-5/16 dual taper .135 would be best, but again, I'm confident the 11/32 will serve me well.

As far as the tip for the Jesels, the adjuster nut on the Jesels is tool steel, so I matched the tip with just that, tool steel.

Also Martin, I'm sorry it didn't cross my mind to call you to see about getting me some pushrods. I completely forgot about trend in the rush of trying to get something out here by this friday. There's a few good guys in the community that I like dealing with. Kip at Cam Motion and yourself top that list.

 

This is absurd. I thought for sure these new rockers wold clear the valve covers for sure, but once again, they hit the valve covers. I don't think it's as bad, but I could still hear and see then hitting it so I shut the car off.

I'm so angry right now I just had to walk away for the night. Maybe it's just the combination of the spdc valve covers and the jesels. I don't know. Unfortunately I can't grind the valve covers because they're carbon fiber. Anyone want a camaro?

 

Why can't you grind them? Too thin?

 

There are some builds coming up with the T&D rockers. I will be highly interested on how the T&Ds work out.

 

Pretty much. I'm afraid I'd break right through. Did you have to grind any on the valve covers? I know you had to make some clearance on the stands.

 

I had to do send grinding on my valve covers also.

 

I've since switched to going with the T&Ds/Comps
