I'm going to build a 1776 for my 73 daily bug.plan is forged 69mm crank from cb performance and engle 110 cam.should I run stock heads or?what about pistons?.i plan on maybe running Kadrons as well.

It all depends on your budget and what you want to do with the motor (type of driving, max RPMs...) Let us know those details and someone will help you out with suggestions.

Well I don't plan on racing on the track all of the time but I do like playing with my cars once in awhile (I drive a 97 golf everyday with obd1 head 270 cam and so on).i am on a budget but I know you have to pay to play.i just want it kind of reliable to

With a stock carb that won't be any better than a stock 1585cc motor, The 110 cam pretty much dictates Dual carbs and Port matched or better heads. If you went to Weber 40 mm Idf carbs they you could run 40X35.5mm Valve heads instead of stock 35.5X32mm Valve heads but your going to need 1 5/8" extractor exhaust with j-tubes or large heater boxes.

So I should do 100 instead of 110?

Wed Jun 04, 2014 2:02 pm

My take:
Cb perf 69 crank
Cb 13lb flywheel
Cb 2241 cam
AA 5.4 I beams
AA 90.5 A p/c's
Steve Tims super stocker 37x32 heads( order last to have heads cc-ed to cr target)
forged 1.25 rockers w/ chromo lashcaps
thinwall chromo ctf pushrods.
All internals and pistons balanced
Stage 1 kep w/ daiken disc
1.5 deepsump
F/F schadek 26mm pump and filter adapter setup
8.5-9 cr
This engine will need a breather.
Have your case decked .030 flat when opening to 90.5 bore or if case is already cut, have bottom of cylinders turned down flat .030.

This engine will run all day.

The Key to choosing your cam is going to be: Where do you want your engine RPM's? But when you say you may run a stock carb then people here are going to say that you can't run more cam than the W-100. I have done it and it works but the engine had a little less torque down low than a stock engine would have had and it had almost no better improvement up top. Check out this thread where I say I want a cam that will run with a stock carb. Which cam, heads and exhaust would you run and why? One vender told me there are only 3 cams to choose from, CB-2280 cheater Cam, CB-2231 and the W-100 and perhaps a 4th the CB-2228 a milage cam.
But put on dual IDF or DRLA Carbs and the rest of the cams like the Scat C25-C35 and the Web-Cams like the 163 come into the picture. It just depends on how many RPM you want your engine to run. When you cross the threshold into the W110 Cam area you must beef up your lifters and push-rods and valve assemblies using single HD valve springs on your heads. When you cross the 290' Advance threshold you looking at Dual High Rev Valve springs and Heavy Duty Aluminum Push Rods and lightened lifters etc.

I'm still learning about engines but i think 6k Rpms at most.dual Kadrons are considered stock?i know not to run a 34 pict3

No Dual Kadrons would not be stock the Solex PICT 34/3 would be stock. I have not tried the Dual Kadrons yet on a engine. But I would think they would allow you to run the W-110 Cam sort of OK, but they won't support 40mmX35.5mm or larger valve sizes! Probably L3 heads would work well with them and the Mofoco Super Street 040 heads.

Wed Jun 04, 2014 6:08 pm

I know you can get kadrons with different size venturies (I cant spell that word lol)

It was stated in his first post...
Obviously it will run better with duals, everyone knows that. But we dont know if he already has the kads.

Kadrons will work great with 40x35 heads and cam of around Engle 110 specs, though you are better of with a 1 1/2" exhaust. 40IDFs will work better, but Kadrons will be fine.

I always keep an eye out for Dell's for sale here on the Samba: Right Now these: Dellortos 36 $425.00 Price: $425.00 and these: nice set of Dellortos 36 Price: 400 are for sale on The Samba, These carbs may not be big enough to support "jfats808" engine with it's huge valve heads but they would allow the 1776cc engine to get to 6000 rpm with the Engle W-110 Cam and Stock Valve Size ported heads. Once you get these carbs working right they are quite drivable and get as good or better gas milage as the stock Solex PICT 34/3 carb would.

Wed Jun 04, 2014 6:53 pm

The Weber 40 IDF's are a very similar carb to the Dellorto 36mm and would also work well. The Weber carbs are more plentiful, still being made and easer to find parts for but are a little less drivable, and as I understand it the Dellorto carb Jets come in more finely incremented sizes. I think they use the same linkage and intake manifolds and air cleaners here: http://www.cbperformance.com/ProductDetails.asp?ProductCode=3143

now if I were to run kardons or 40mm webers with a 100 cam can I run stock valves on the heads without going bigger valves?

How can you say that you haven't tried them, but that you know they will not work? I have used them on 35x40 heads with an 1835 and they worked great with the stock vents. I have since helped someone set up a pair on a 1904? (not sure of the exact displacement) and he is using CB 044 heads. They run out of breath at about 5500 rpm, but run fine otherwise.

Wed Jun 04, 2014 7:21 pm

Engle 100 will work too with either set of carbs or either size heads. Set budget, pick heads and carbs, then pick a cam. You can get a set of 40x35 heads and 40IDFs for around $1,000 if you shop around.

Let me be more clear, I don't mean to say they won't work just that they would not be ideal "The Kadrons"

The way I think of it is, Something in the engine will limit it's performance, give the cam more duration and it will allow more RPM but then the limitation shows up somewhere else, perhaps Venturi size perhaps port size or valve size perhaps exhaust system. I suppose it's part economics why run really expensive high flow heads then limit their performance with a little carburetor that does not have the turning options your going to need. Another thing too is the port velocity, a 90.5mm chamber is not that big and won't make as much port velocity with big valves unless you get the RPM really up. With the Kadrons I would think the stock or L3 heads would be a good match.

Read here how big things get with the L5 heads with just 40mmX35.5mm valves: 36-38mm venturi's, 1 5/8" exhaust, J-tubes the works!

Here is a nice combo I just built...
1776, fk41, 40x35 revmasters with dual springs, 1.25 rockers, chromoly pushrods, svda, and 40 idfs. Set the deck at .045, flycut the heads to 50cc. 8.74:1 compression. It would run fine with Kads.....

Smooth runner with tons of power. In my buddies 64, 4.37 rp, it is a beast. He wanted a daily with power and on a budget. This definitely fit the bill.

Wed Jun 04, 2014 7:53 pm

Kadrons are cheaper to buy and re-jet than IDFs, absolutely. But, if you get a well-working set for $300 and that is your budget, there is nothing wrong with that. I have both Kadrons and 40IDFs, own 40x35 heads now and owned L3s in the past, as well as ICTs. I don't see why any of those parts could not work well with either Engle 100 or 110, just depends on budget.

Do you have a usable set of heads already? If you need new heads, that's at least $500 out of your budget.

My 92mm pistons aren't that much larger than 90.5s, I have noticed no low RPM drivability issues with 40x35 valves and cam with more duration than w110, in fact there is plenty of low end grunt.
