Is this considered a mild cam ?

Lift .541"/.544"
Duration 284/296
RPM Range 2300-6500

Will I need to replace the springs and push rods with this cam.

cutlassefi

No, yes, and probably. That's a Comp XE284, hardly mild.

What's your application? What are you looking for?

FYI, I do cams as well.

You will also nwant to use at least Comp Cams steel roller tip rockers or even full roller rockers with a cam with this much lift. If you go much over .500 lift youre asking for trouble with stock rocker set-up. You better have a 4speed or at least a 3000 stall converter to run this cam on the street! ( MOO)

I am not looking to race...I just want to beef up the engine and have a nice thump. I was going to order the complete kit.

I do not want something that is going to cause me grief. Any recomendations

Hope you don't have power brakes, that cam won't make much vacuum.

You want a MUCH SMALLER grind that the one above! something in the 260-270 duration with around 470-480 lift! LSA 108-109 much better than those 110-112 ones!! (MOO).

Anyway you slice it --- you should have a good cam "expert" analyze your "needs" and all of your factors in determining what is best for your desired results. Car weight, tire size, headers or no, rear gears, intake and carb, coupled with "what you want to do with it" all are factors when selecting a cam! Ultradyne and Bullet cams are my choice when it comes to having your needs "diagnosed" and the correct cam selected for your car. A lot of companies have a "hot line" about cam choice and all they know is cheby and the think those grinds will be OK for OLDS ---wrong!!! Ultradyne and Bullet KNOW OLDSMOBILE!!! (MOO!)

What would you recommend?

How about this one!

I would suggest at least "one step smaller" than this cam. Contrary to what they say in their ad -- ( unless you "read into" their message) this cam does NOT work well with a stock converter!! In their ad they say it works "better" with at least a 2000 converter. 296 is too big for a stock converter!

This is a nice 4 speed cam -- especially with the 107 LSA!! But I would never use it for a customer unless he wanted to go with a converter!! ( MOO)

CLcutlass

Hi Guys...this is fairly new to me. What happens if I run the stock converter. How would I know what kind of converter I have? Ans what will upgrading to a 3000 converter give me.

cutlassefi

Unless I missed something you still didn't give me your specs so I can't tell you, nobody really can.

CLcutlass

What I have is a 455 stock engine out of a 68 Delta 88 so I really do not have any specs. I want to put this in a 70 cutlass supreme and am wondering what is a good combination for a cam, manifold and carburator to have some good street performance. I emailed Jebs and they came back with the equivlant to what eldbrock offeres for the top end kit but I am learning here that the cam was too aggresive.

cutlassefi

O.k then your compression will be about 9.0-9.5:1. I would use a Performer intake, 750 or so carb and cam like this;

220/228 on a 110, with .504 lift. It's stock valvetrain friendly and will give great midrange torque as well as work with a stock converter. Plus you will hear it a little as well. If you have a gear that's 3.08 or numerically higher you'll be fine.

Jmo.

You can use a carbide bur in a die grinder to lengthen the slot in the rocker to allow more lift, but the retainer to seal/guide clearance probably will need work too, either milling down the guides, using different retainers with less downward protrusion, and/or seals with thinner tops. Stock rockers with the slots lengthened will work with over .6 lift, but I wouldn't go over about 400 lb. valve spring pressure open with them if you want them to live a long time.

oldsy

im in kind of the same situation too.would you guys consider a cam with lets say a 218/226 duration a good street cam?with a stock converter,750cfm carb,3.42 gears,and opened up exaust if that matters?

My442

I run an Engle 20-22 cam in my 4 speed 70 442.

It is 226/230 with a 110 LSA.

Has a nice lumpy idle, and pulls really good.

Use Comp roller tip rockers with it.

Made 400 HP on the dyno, and has great street manners.

ah64pilot

I've used the 20-22 cam in all of my engines except this last one. It makes plenty of power for street cruising, you'll be happy with it. AND you can use it with stock valve train, although I would suggest stepping up to at least a roller tip rocker and hardened pushrods.

.496 int / .512 exh 226/230 @.050" 110 LSA

CLcutlass

who sells the Engle 20-22

cutlassefi

Engle or Mondello, they can be mechanically noisy though.

Check out Chadmans response.

I've never heard my Engle cams at all, but if you do hear it...just do the exhaust right and you won't hear the noise

ah64pilot

Also, I don't think that 20-22 is going to be loud...it's not too aggressive. .496/512 226/230 @ .050"
