Mancini Rockers

jusglazin · Dec 12, 2020

Has anyone ran the Mancini Rockers on Edelbrock heads? How the fit and the alignment? I see Harland Sharp has a specific set for the edelbrock and Trick Flow heads that are shorter to get a better pushrod angle. Wonder if the Mancini set will be an issue before I pull the trigger.

I believe the Mancini rockers are re-badged Harland-Sharp. Not the full roller.
Double check push rod length.

Yes I have heard that as well but which ones? Harland sharp makes two sets, one for stock heads and one for Edelbrocks. I have asked them and they say they will work but that makes me wonder why Harland added a new part number for Edelbrocks

I'm running them on a 470 with Edelbrock RPM heads. No problems. Only issue was push rod length and a call to Manton fixed that.

I use the mancini 1.5s on RPM heads and a geometry correction kit from B3 racing. They're good solid rockers that I wouldn't hesitate to use again if the higher-dollar rockers weren't in the budget.
The issue is not the pushrod side but the valve side geometry, which can only be changed/improved by moving the rocker shaft (or in this case, re-designing the rocker).
I would love to see some pictures of someone's valve tip swipe pattern with those special Harland rockers to see just how much of a difference they make. Of course the cam lift has an effect on it too...

Hughes makes the rockers on my 493. No problems.

Thanks for the feedback!

All aftermarket rockers can stand to have the geometry fixed on a big-block Mopar. That's why I'm anxious to see how well these 'made for Edelbrock and TF' rockers compare.
Unless I've missed it nobody's put up a picture either here or on FABO as of yet.
I hope they're better seeing as how they cost an extra $150..

I have stock heads, but went with T & D rockers. Had to use new pushrods. Liked the T & D over the Harland Sharp

I put the Harland Sharp rockers for Edelbrock heads on a set of Trick flow heads. They will work, but... If you want the geometry correct the rocker shaft needs to move in and up like stated already. Called B3 and Mike made me a set of shims. B3 sells a rocker that is correct without shimming. Talk to Mike, he is a great guy.

I have a set on my 493. They are bushed, no bearings. The fitment was okay, I did have to resurface a couple edges on the spacers to allow a more free movement.
