Rev kit for FE?

[Carnut427]

Does anyone make a rev kit for the FE?
Thanks in advance...

Hi Carnut,

What do you mean by a rev kit?
It may be it's just me that dosn't know what you are asking for since i'm not much of a mechanic but it could be others don't know what you are after ether.
Maybe if you could give us a bit more explanation?

If you are talking about a rev limiter then the answer is yes. MSD as well as others offer ignition boxes with the ability to limit your RPMs.

Rev Kit is a sport compact term. Rice burners are limited physically and electronically from excessive rpms. As no new car has been equipped with an FE since the early 70's and no truck has been made with an FE since 1976 there are no computer controlled restrictions to overcome. You may choose to do so by installing a rev limiter like the MSD 6AL CD ignition or other digital ignition box.

Physics is your only enemy. FE's can be made to live well past 7500. Some have been known to live beyond that. Balance and airflow are key. Cam duration, lift and valve size, 2.25" intake and 1.73" exhaust are your only limiting factors on a standard bore 427. Shelby and Genesis blocks can go to 4.5" though valves larger than 2.25" are still limited by head design.

The question is why? if you are pre disposed to a techno approach to your car I suggest you look at a low revving stump pulling 428 or 454 (stroked 427) with a 6 speed trans much like the Viper does. The V-10 makes max HP at 5500. but has a theoretical top speed of 300+ mph.

Dan is talking about a second set of springs that apply force directly to the lifters to help keep the lifter from floating, so the valve spring is only working against the inertia of the pushrod, rocker and valve. The two sets work together to keep the valves from floating. They are available for Big (and small?) Block Chebbies, but I've never seen a set for an FE.
Big problem an FE would have is, what would the springs push against? The Chevy rev kit springs push against the bottom of the cylinder head, but the Fe has no cylinder head "bottom" to push against, since the pushrods come out through the intake manifold. I guess they could push against the manifold bottom, but how the heck would you install the manifold?
Anyone have any ideas?

You would be able to use them if you were using something like a Dove (or original I guess) tunnelwedge-type intake where the center section under the could be left open while the intake is bolted down.

Most rev kits cost around a hundred dollars, seeing as how they're basically the equivalent of a steel 1-foot ruler with pushrod holes punched through it. It doesn't need to be very strong, just flat, just needs to take the minimal force applied to it from the springs between it and the lifters. I imagine a flat base could be spotwelded, or bolted to the bottom of an FE's intake fairly easily if you wanted a rev kit...they're not rocket science, and like I said, they're fairly cheaply fabricated.

There are, of course, those who will try to tell/sell you a rev kit as a cure-all, be-all, piece of rocket science. You need to be very wary of those types...again with the -->

Yes mr0077, I thought about where would you put the plate a while after I posted. Another thing a rev kit does is keeps the lifters in their place if you bend a pushrod. They're usually only used with roller lifters, and with solid rollers they keep the lifter on the cam so the lifter doesn't bounce. It just happens I do run a Tunnel Wedge, but even on that, the center cover is screwed on from the bottom. Well, it was just a thought...
Thanks for your replies,
Dan

Dan what you are looking for is on E-Bay. There is a couple kit with the plates lifters and springs. The price will not be cheap. I think it was comp cams. Saw it last night. The lifters are special for the springs to fit inside of the lifters. Check it out. The only other place would be PSE in Cali. Ask Paul. If you are going to get this crazy, I would look at the solid roller lifters with the larger wheels and have the block bores made bigger and bushed. Good luck. Rick Lake

Personally, I think this whole thread is part of a scam, but if not, you would want this in order to use the PSE rev kit currently being (in my opinion) shilled shamelessly on ebay:



If dealing with a valley plate that screws in from the bottom on a tunnelwedge is just too too much trouble for someone mounting a rev kit on an FE.

OR, you would simply wait for Blue Thunder to release their FE/Yates heads, which would have the extended runners that would more easily allow you to use a rev kit, from either a BBC or BBmopar, both of which have similiar bore spacings, and which, from a rev-kit perspective, use the same sort of springs over the lifters.

Thanks Rick...but I've already got the cam and Crower HPPO roller lifters. Couldn't find Pro Stock Engineering on the Web...do you have a phone # or address? Their rev kit appears to bolt in with 3 bolts, don't know where that might be offhand.

carnut427 Hi Dan Paul Berdoian # is 909-845-2900. I think he is in Cali. I have talked to him twice. He is rough on the edges. Some of his trick parts. are great. I have seen the FE intake with the multi tops. Think it's a great but cleveland intakes, guess they are the only ones with the right spacing. I know he has a couple of warehouses full of race stuff. Good Luck with barky. Rick Lake

Rough on the edges? That guy is certifiable! He says you have to use his jigs to locate the drilled & tapped holes to mount it, which really means he has to mount it. Better off pretending he doesn't exist. Too bad, because it sounds like a lot of good parts and ideas aren't available because of his anti-social attitude.
THANKS anyway Rick...I guess the Crower HIPPO lifters will have to do...if they don't I can always say they should have...

[RICK LAKE]

carnut427 Dan if you have the plates you can figure out how to mount the plates to the bottom of the heads. Paul said that everybody has stolen his Ideas from the 70's. Alumimium oil pumps, gero gears for them that pump more oil, dual pickup pumps. The intake set was his. I have hear the other side who got stuff from him saying that it didnot work. Maybe the parts where not installed right. Contact the ebay seller and see what he said. He might zerox a copy of how to install the system. I cann't see it being any harder than any other motor getting the same setup. Remember Smart people are both certified nuts and bastards at the same time Rick Lake

Very true words, Rick. The only bad thing about retirement is I lost a fully equipped shop in the process. I could've made my own plates, and yes, installed them. The plates aren't just a bunch of holes, they have to have a counterbore in them to locate the springs, which leaves out the home builder. Just not that important to me right now. I was just trying to make sure the solid roller lifters have a nice long life. I don't like parts breaking.
I only found the add with the cam, lifters, springs and rev kit as a unit, lots more parts than I need. I did send an email to the seller asking about the rev kit yesterday, but no reply.

carnut427 Dan you can build your own with a drill press. You built a car? You can build a plate. Cardboard and etching paper. If you don't like this try Gessford. George can have anything made. He just finished a cam sensor for FI with the 4 coil setup. I don't think the springs are that special. Comp cams , Crane, Isky, must sell these springs when one breaks on race car. You might even get the plate from Crower. Tell them you race FE cars in D stock and the plate broke, see what happens. You could get LUCKY Rick Lake

I'm going to let it be, Rick. Thanks for the help.
