Trick flow 240 rabbit hole

[Curiousyellow71]

We already had the mancini 1.6 rockers so we tried them on the trick flows and they fit as good as they would on any bb oem head IMHO. The push rods are nearly 1 inch longer then oem heads. Ours TF240s are on a 440 w a.670 lift solid roller, they fit wo any modifications. It is tight on the pushrod but clears. That beings said most the bb mopar heads could have a better sweep pattern (like said look up b3 racing engines). We are running it the way it is. It would be interesting to compare the mancini rockers we have to the harlan sharps made for the TrickFlows. My thought is in a max effort the special HS rockers would be better. The good thing about the mancini's is there is no needle bearings and from what I have seen Harlan sharp rates them the same as there own brand of rockers w needle bearings 1200ft-lbs. Big time overkill for the op. The mancini's rockers go on sale occasionally, very good value for what they are. We certainly are not the only one running mancini rockers on TF heads. I did a bit of research before we tried it.
The TF240s impressed me on our flow bench at the lower lifts. I think it's going to be a stronger performer over any of the other heads available with a smallish cam. But that's just my instinct. Nothing to back it up.

Fun fact!!!

Th Special “Made for TF heads” HS rockers…..existed before there were TF heads for Mopars.
The E at the end of the HS part number is for Edelbrock.
The std HS rockers are sorta too long for the RPM heads, so HS responded by offering a shorter set.
And that’s what TF used when determining where to locate the rocker stands.

So, any of the “shorter” rockers will have a similar roller sweep on those heads, including the Comp ultra pro magnums and old Crane Golds.

I bought the H.S. "E" rockers for my TF 2450s just to remove any doubt about whether they will work.

What part # are the Mancini-brand rockers that fit the TF heads? I might return the H.S. set if they are the same thing just without the needle bearings. They list a few varieties but unless I missed it they don't say which particular set will fit the TFs. Sure I can call them but since we're here...

AFAIK, the HS made Mancini rockers only come in one variety, in 1.5 or 1.6 ratio.

I myself have never test fit those on TF heads, but I have test fit them on several sets of Ede heads, which looked good to me.
I have also test fit the Comp UPM’s on both Ede and TF heads(on the TF’s some minor clearancing on the two end rocker stands is req’d), and the sweep looked good to me on both.

I find the Mancini rocker pairs to be pretty snug on the Ede heads(using the Mancini aluminum hood downs).
My solution on those is to trim about .015” off the thick spacers that are between the rockers.

The mancini are close the HS part number below. The HS rockers that end with a E are a bit shorter on their contact from what PRH mentioned above(always good to follow his advice).
We tried the mancini's 1.6 below and are satisfied with the contact pattern. No modifications to anything. I should have taken a picture. They are on TF240s with .670 lift. The lift can certainly affect the pattern.

Mancini's pictures are not always correct..ours are NOT anodized red and are 1.6.

With that cam I would probably go 1.6 rockers to work the trick flow heads a little bit more.

I just put trick flow 240's on my 505 when my Edelbrock heads needed more repair than could be done in a timely manner. I took the years old Harland Sharp rockers that came with my used E heads and they bolted on the 240's nicely. About the only good thing that has come out of me buying those E heads thus far.

I love the TF 240s on my 500" stroker. Solid flat tappet with Isky nodular rockers. Had to have custom rocker shaft spacers machined. Bomb proof set up.

Have you looked into Comp’s Ultra Pro Magnum Rockers?

That is a beautiful looking engine. Who would have thought of B5 blue on a big block?

I love Andy and the parts he makes. He does us all a big favor by doing all these dyno tests and sharing all of his build information. He will milk a combo forever and get all the power it has to give. I don’t build engines with big roller cams but if I ever wanted to I would go reread everything he’s ever written. I appreciate him.

agree, he hasn't been on here much lately..

I notice the are straight rockers, my victor knock offs use .600 offset rockers ....

Yes they are straight, even on the maxwedge sized 270s. Most the heads that have Maxwedge ports have to use offset rockers to get the pushrod out of the port, like the victors. I think the 270s might leave some flow on the table because of that.
