Personally, on valvetrain parts, I try to stay away from anything cheap, of unknown name, or anything that is questionable at all. And to me, those fit all 3 of the above criteria.

Scorpion is a new company and makes a high quality precision rocker. Far superior to Harland SHarp. They are ratio correct, lighter, and stronger compared to the HS product. HS has not changed their design since 1960 and it shows.------------------

We took the line on in 2001.
When compared to HS, Crane Blazer, Lunati, etc. "econo" units, or over seas mail order "no name" crap rockers Scorpion stuff is fantastic.
The WORST junk I have ever seen are the rockers that Tommy Johnson's Mail Order House sells for $149. I would not use those on a chebbie.  For absolute top of the line premium rockers my choices are still Sig Erson for stud mount or T&D for shaft mount.  ------------------

The Comp ALUMINUM units used to be (and I assume still are) made by Dove. They are what I've got on the mustang, and have held up GREAT!Dove also made rockers for Blue Racer, Speed Pro, and probably others. Mine have been ABUSED for around 8-9 years now, and are still going strong. I have ZERO complaints. Good Stuff. I have no experience with their 'pro magnum' line that is made from steel. Erson makes a really nice full roller shaft setup for the FE engine. Everyone on the FE forum really raves about them. They are $600 complete, and shafts, stands, everything is included. They are fully rollerized, and are designed to NOT come apart in case of shaft breakage, etc. The engineer who designed them used to come onto the FE forum every now and then for feedback, and kept making running revisions to clear out any major bugs anyone had with specific applications. I purchased a set for a stroked 427 I'm in the process of gathering parts for, that will go in a buddy's car in the near future. There sure is a lot to learn about FE engines, and patience sure is a virtue when trying to accumulate parts and information! Oh, sorry for rambling... I guess you figured out what you needed to know about Scorpion rockers....... and Comp (Dove) rockers are also good. Erson stuff is nice as well. Good Luck! ------------------

Mike, something you need to know about FE engines is that the block moves a lot when things are torqued down. I recommend at least having the water pump torqued onto the block before boring and honing. I personally would bolt everything together that I could before doing any machine work.When the heads are torqued to the block the valve seats distort and the end cylinders will leak excessivly. I tried doing a valve job with a torque plate fastened to the head for one of the local stock elim racers and he said it helped but there was still leakage. I'm not saying the FE won't go fast just that the guys who have figured them out have had to deal with this problem. John

Thanks John,But the block is already 0.030" over, so he's re-using the existing pistons. (which have very little wear) This sideoiler spun a rod bearing around 20 years ago, and the owner wants to restore it to it's former glory. The TRW #2298 (428 crank) pistons have had their domes shaved to flattops. It will be wearing ported (by me) Edelbrock heads with 2.19" intake and 1.75" exhaust valves with an Erson rocker setup. It will have a medium riser (C7ZX) dual four intake with the an original set of carbs. It will have a solid lifter cam of around 245 @ 0.050" on the intake. The block will get the hydraulic lifter galleries plugged, and the bearings will be set up loose. The oil to the rockers will also be restricted. It will be a streeter, but should be able to hold it's own at the track as well. Now, if I ever get my engine put together, this one should be well on it's way this summer. It will be my first FE... a stroked 427!  I've done a LOT of reading and studying on these old beasts. There sure is a lot to learn with these things... ------------------

Mike, if it hasn't already been done, one trick that we always do on FE's is chamfer the main galley oil feed holes to match up with the bearing halves.
Also, I always used fully grooved main bearings on the 454 stoker deals along with a high volume oil pump.------------------

I have a set of Yella Terra 1.7 roller rockers that I am considering using on a 351C project. Only thing is, they are the bolt down type, so no solid lifters, but no machining needed either. I have heard they are good rockers too.

Thanks guys,The engine will have a high volume, high pressure pump... and will use those Federal Mogul 3/4 groove race bearings. The crank is a factory Ford 428, and the rods are LeMans units with ARP cap screws. I'll definintely chamfer the bearings, Alex. For this EXPENSIVE engine, we're definitely looking to do everything we can to make it live a long, prosperous life. We're looking for around 0.0030"-0.0035" on the mains, slightly less on the rods. The engine will get synthetic 15w50. Again, we're doing everything we can to keep from spinning bearings. That last couple horsepower isn't really all that relavent in this expensive 'dinosaur'. Thanks for the input! ------------------

I hope so. The entire valve train on the Falcon is Crower. Crower roller lifters are sure different from Lunatis. Lunatis have a riveted crossbar and the lifters have to be installed in pairs. The Crowers have a dogbone that comes off. I must have 6 sets of Crower triple springs, most of which likely have one pretty easy season on em. The retainers are even Crower. I have all but one of a spare set of rockers. One broke some years ago and Steve bought a whole set. I also have one set of new lifters and a used set that could be rebuilt, I'm sure. Two things that I haven't got to put another motor together are rods and pistons. I have 2 standard cranks and 2 good blocks, one +.030 and one +.020. I hope the Crower stuff holds up. I've got a fair amounr of it.  ------------------
