2110 What Cam?

[Gil G.]

I am currently building a 2110 engine out of my existing 1776. What would be an ideal cam for the street? I don't plan on taking my car to the track. Looking for good reliability and longevity.
*New AS 41 case machined by Berg for 90.5's
*New AA 90.5 pistons/cylinders for 82mm stroke.
*New 4340 CB 82mm crank
*Heads 35.5x40mm ported polished /dual springs
*Cam Curently Engle 110/w Cb's racing lifters
*Exhaust 1 1/2" merged Berg with dual muffs
*Stock ratio rockers w/Berg heavy duty shafts
*Berg 42 Specials (Weber 42dcnfs)

Can I continue to use my Engle 110? I know it will require some clearance work. Or should I go with something else with my combo? What compression ratio should I shoot for?

FK-8 is a beauty for a 2110 if you're willing to spring for 1.4 rockers and pushrods.I don't think a 110 will do that combo much justice,unless you're building a tractor for a bus.

[Gil G.]

Will the 1.4's be hard on my valve train? Or just as reliable as the originals with proper geometry?

[Marv [UK]]

depends if you're going to be running hard. Are you running dual high strength springs or more, er ....springy... springs and whether you're going to be running at really high revs

If your valves are likely to float at high revs, run 1.4 ratio rockers. It will reduce lifter bore wear. Your cam will get worn regardless. High strength springs will do that whether they are 1.1 - 1 or 1.4 - 1

If you're running low revs and less duration and want longevity on your bottom end, run a higher lift cam with low ratio rockers. Reduces the lever arm of the valve springs onto the cam face and reduces cam wear but proportionaly can increase lifter bore wear. But as you're running lower revs, the lifter bores will be properly lubricated.

It's a balancing act over performance versus longevity.

FK8, C25 or C35, W120 Even a C45 as you've got a large displacement.

Seen a 2110 running an FK89 and still idled nicely

[Gil G.]

Good info guys keep it coming.

[Glenn]

FK-8 all the way.

I was convinced when I drove my friends 2110 with a FK-8. Now I have one in my 2180 and love it.

Sounds like the FK-8 is the way to go..
Should work nicely with the 010 I got from you Glen.

John Plow's 2110 (from Cal-Look.com)

40x35 ported heads, FK-8, dual IDAs, Bosch 010 and Blue coil.

It's a sweet engine.

Keep the 110 if your going to keep the 1.25's or for more power step up to a fk42 with 1.4's

I think the 110 with 1.25 would be okay too....since you already have the parts.

The Lift with a 110 is .397 at the cam, and with 1.25s it would be .490 at the rocker. Then depending on the brand of 1.25s rockers, you might actually be more like 1.3s, which would put you around .510.

Also, there is good chance you will not need to clearance the cam for your engine.

[Gil G.]

Thanks for the replys guys. Keep them coming.....
I have stock ratio arms at the moment. Don't know what direction to go though. Seems like everyone so far is for the Engle Fk-8 and 1.4 arms.

[Viande]

FK 8 and 1.4's would be great for a hot street engine. Just make sure your heads and valve springs can handle the increased lift.

The bitter taste of poor quality lingers long after the joy of the cheap price fades away.

[perrib]

If it is not worn I would keep the 110, step up to 1.25 rockers if you want. The power band is going to be right where you need it. The FK 8 is going to be quicker at the expense of the bottom end. Then you need to buy close ratio gears to use the benefit of the FK 8 and without a five speed you lose highway speed. With a 26" tall tire 4.12 RP and 1.56 and 1.21 third and fourth gears at 3000rpms you only run 50 mph and 60 mph. The engine will take but it it is noisey. The 110 cam has a lower redline so the stress is less and should last longer.

[MinamiKotaro]

If you don't intend it to see track use, the 110 would provide stump-pulling torque for the street.

If you want to use a ratio rocker cam, an FK-7 would be a good torquer with 1.4s.

If your talking about reliability and longevity I'm suprised not one person has mentioned this. While everything is apart send the case out to get its lifter bores sleeved with silicon/bronze. This will provide you a rock solid bushing material that will take the side loads of a lifter recieving stiffer valve spring pressure. You will NOT regret it!!

The fk8 still has excellent grunt down low with a stock ratio 1st gear with a 3.88 or 4.12rp especially for a street car.

I suggest getting the china made 1.4's from CB. Also get the tool steel cup adjusters they have. Scat 1.4's are also very nice but IMO those cup adjusters they no where as nice as a the tool steel ones from CB.

An Engle 110 is a waste of time if your going to the troubles of building a stroker.

It sure would be nice to hear the flow characteristics of your heads. Port and polish is really meaningless unless you have some flow numbers and port velocity (fps) numbers. Having a larger cam with a head that isn't ported properly will just create more turbulence and be a dog. But all in all the fk8 isn't a big cam at all so it'll still be a decent choice for a 2110 if you want to pick one blindly without alot of details of the head flow.

If your gonna use those used lifters you have you better send them out to get resurfaced.

Alan thanks for the info. The heads were done by an old vw racer. I'm not sure about the flow on them. The current (1776) has never been fired so the cam and lifters have no wear on them.

[madmike]

I like the W120,It's been around for years and still going strong can be used with stock rockers or 1:25's all power is done by 6k so you don't have to rev the $hit out of your motor ,thus long life my 2 cents,Madmike

[scott s]

I agree....the 110 would be a waste with the 2110.
If you keep the 1.1:1 rockers, go with a 120.
With 1.4 rockers, go K8 or XR-302.

Thank's guys! I think I'll try the Engle 120 with my present rockers and see how it does. I can always change it out down the road. And I won't have to explain the credit card bill to my wife.

[vince1]

FK43 huge lift for torque, small duration for large powerband, have a custom made FK43 intake / FK7 exhaust (less stress on the exhaust valve train) cam in my engine and it pulls like a tractor from 2K to 7K.
