Solid roller on the street Empty Solid roller on the street

Post  64galaxie June 24th 2024, 7:46 pm

Cam recommendation needed. Switching cylinder heads and cam on my 460. Has Wiseco true street flat tops in it, eagle h beam rods and stock crank. Switching from lightly ported doves with 2.25/1.76 valves to out of the box TFS 290’s. I’m thinking compression will be just over 11.0.1. Stealth intake. Crites 2” headers. Also putting Super Sniper stealth efi on it. Has a c6 in it now with a 3800 converter with 3.70 rear gears. 64 Galaxie that weighs 4200 with me in it. Eventually will have an overdrive trans in it. Have been thinking about putting a solid roller in it with bushed dlc lifters or just go hydraulic roller. Car has only been to the track a few times. Best has been a 7.70 1/8. How much better would this combo run and any recommendations on which direction to go on cam? What’s opinions on this cam? https://www.compcams.com/xtreme-energy-248-254-solid-roller-cam-for-ford-429-460.html

Probably a decent cam but you might be able to go a step up from that one .050 Duration Wise!!But i'm no expert maybe Randy will respond with a better choice or maybe he can have a custom grind done for you!!And it looks like that cam is in stock i guess that's a bonus!! i would imagine it should run a lot better with the Solid Roller Cam and Trick Flow Heads!!What are the specs on your current cam?

That's a good price on that cam. Like Mark said Look's in Stock, another Big Plus. Here's an old article on tests on a 514 SVO Crate engine with the XR292 cam, from back in the day when they were new. They also tested the XR286, which is the one you listed.

Richard Holdener put out a remake video of the Dyno Tests, in the linked below articles, of I believe, 3 of the Comp Cams XR Solid Roller Grinds, not long ago.

For a Mildish Street Strip camshaft, the XR286 you mentioned sounds like a good choice. Should make around 600HP with your combo in my opinion.

Here's the Richard Holdener Video I mentioned above on the 514 SVO Crate Engine Tests.

Same as Mark asked, what camshaft do you have now? Do you plan on alot of street diving and extended idle in traffic time?

PS: Lunati makes a pretty close clone of that Comp XR286 Roller for 411 bucks and Jegs as well as Jegs FleeBay shows it in stock.

What cam are you running now?

Got to watch getting too big on camshafts with overdrive and low cruising rpm under load.

^  A little Catch 22 balance in the mix, with 11/1 plus compression and the camshaft Dynamic Compression bleed off characteristics with the bigger cams, also. If he want's to run on Pump Gas anyway.

OP will you be able to have manual control of your torque convertor lockup when you switch to an overdrive transmission?

The good news is it looks like all of the CompCams XR Series Solid Rollers for Big Block Fords are back in Stock Now and on Sale, to include XR 274 280 286 and 292. Cool

Is Cost of any Concern?

https://vincentperformance.com/shop/bam-b-2010-16-bb1/

The BAM DLC roller lifters are a chunk of change.

The old SVO Crate 460's, the first ones with flat top pistons, with the aluminum CJ's an around 11.5/1 Compression where 550 or 560 HP with a SVO C460 HFT camshaft. The SVO C460 camshaft spec.'s below.

https://www.ragtop50.com/data/85.pdf


With the TFS 290's and an XR292 Roller you would likely be in the low 600's, if all the stars align.

If you can get a HFT or SFT camshaft to break in without the lobes wiping, I don't think the cost and problems with roller lifters on the street or worth the Pain for the Gain, myself.

Another member here just put this camshaft in his 552 with aluminum SCJ heads and cheated breaking it in with light springs by mistake. He had to switch to dual spring because of valve float problems.

https://www.summitracing.com/parts/cca-cl34-245-5/make/ford

^ It's the camshaft above, and out of stock again. It is very close to the SVO C460 camshaft but, on a 112 LSA which will give a smoother idle then the C460 camshaft as well as more vacuum.

It has gone 11.50's so far in a full weight Fox Body, with a 850 double pumper at highish altitude.

There is another member here with a 1964 Galaxie 521 Kassie P-51 Heads big roller camshaft Comp. 34-715-9 .727" lift, and 268/276 at .050" 108 LSA and around 10/1 compression. I believe his best time was 7.0 in the 1/8 mile until the roller lifter took a shit. Link below.

https://www.429-460.com/t28022-521-with-holley-sniper-4500

^ It was a Dyno Proven Engine at 720HP. I would say a 460 running 7.70's at your weight with mildly ported D0VE's is excellent.

I think that cam could be a good choice however, I think your intake manifold choice for the street, is not.
A 2 plane intake usually will provide more low RPM cylinder pressure  which leads to some detonation.
I think a "Torquer II" intake would be better here.

X2 on your last sentence i think 7.70's in the 1/8 mile with Mildly Ported DOVE Heads and 4,200 lbs. is pretty good!!

I'm guessing that cam is a Hydraulic Flat Tappet and your .050 Duration now is more than the Solid Roller you mentioned about buying!!

That's a healthy HFT camshaft. I bet those "mildly ported" D0VE heads may be flowing better then they appear.

If that cam does not show excessive wear on the lifters or lobes I would keep running it.

Change the springs and retainers on the TFS heads if they have the solid roller springs on them, which they should, good to .680" lift.

I don't see a solid roller cam like the ones mentioned gaining very much HP or E/T reduction over that HFT.

The Hopefully much better flowing heads is what I think will be the biggest factor in increased performance.

What Dfree said about the camshaft loading up in overdrive at low speed load, I can see with that cam though.

^ I can see the same low speed problem with the XR286 also, but the 110 LSA over the 108 you have now might tame it a little. A 112 or 114 LSA would be even better at taming the low end camshaft loading with a oversized street cam. Problem with that is you will loose low end torque you need in a heavy car.

I was just thinking the same thing ... if that present cam and lifters is not worn, the smartest thing is continue to use that cam set-up.

As already said, just be sure to use the correct flat tappet valve springs on those new heads; a set of good steel 1.8/1 rocker arms will get you some more valve lift if you want that.

That cam looks about the same as the CompCams XR292 with a little more exhaust lift.

https://www.compcams.com/xtreme-energy-254-260-solid-roller-cam-for-ford-429-460.html

TFS show .680" max lift on the 290 heads.

https://www.trickflow.com/parts/tfs-53410002

You may squeak by with that cam, I think I would save myself the aggravation in case it did not though, IE too close to spring bind.

May be irrelevant, but it is info. Somewhat similar combo & this is the cam that Lem spec’d for me. I told him I wanted it to pop wheelies on the street.

Not saying you can tell from a picture but, the wire gauge sure looks thick on those outer springs.

Being Titanium Valves and fancy retainers I would be suspect of the pressure of those springs.

PAC makes some dual valve springs with very high seat and open pressure. If that was the case and it is much higher then the Comp XR292 cam needs you will just increase your roller lifter wear, as well as everything else in the valvetrain.

Just my 2 cent's, I would pull a couple off and test to see what you have.

PS: For what it's worth, CompCams recommends a 954-16 spring set for the XR 292R-10 camshaft. The old Comp catalog that had the seat and open pressure, instead of just the spring rate, showed 195 on the seat and 515 open pressure for those springs. They are out of stock now also, so hopefully what you have is close.

That’s a safe shelf cam, just make sure to use some better springs then the 954-16’s

And don’t use the cheap comp lifters. Get some Bushed Morels or Crowers, they are not cheap but much better parts for a longer service life
