I'm doing a stock rebuild on a '68 1500. I'm trying to decide between an Engle 100 and a new stock cam. Will there be any benefit with all other parts being stock? Is it advisable and will there be any downside to the Engle?

A W-100 is just about stock.

Never used one... I consider the W-110 the first upgrade.

The 100 cam is a perfect choice for a stock build up, it has better lift & duration than stock, requires no other mod, you can use the stock carb, stock exhaust, distributor and will feel the difference. Make sure you use the cam makers lifters.

The Engle W-100 is the best step up from stock. It has 0.383" lift (at the cam), 0.421" with the stock 1.1:1 rockers and 236 degrees duration (at 0.050"). Itis very smooth and works great with the stock carb or some Solex-Kadrons (or other small twin carb kits) and will give you excellent fuel economy.

I ran a W-100 in my Westy for many years and the improvement was certainly noticeable, first with the 34-PICT carb and more so with the Solex-Kadrons.

The W-110 is not as smooth in my experience (too much duration: 247 degrees), but some don't mind it...

The 100 has similar duration and ~0.100" additional lift compared to stock. It isn't known to chew your lifter bores and idles and runs very nicely. I talked to a great head porter and he did not like the 110. He said if you went that way you may as well go 120 cam. But to help small displacement with torque and If you probably won't do too many 1/4 mile passes the 100 is a good choice of cam. Stronger running than stock.

That's what I needed to hear. Gonna go with the 100. Thanks for the input guys. This board is great for a newbie.

The more duration a cam has (the longer it holds the valves open) the more power it will take from low revs and add to high revs all things being the same.

There are many cam grinds in between a stock and engle 100.

For a bone stock engine, i would personally stay stock or go for some thing with a bit more lift to add TQ to the lower rpm area.

Check out the CB performance cheater cam, and there other fuel efficient range

The 100 will loose bottom end power and add it to higher rpms on a stock engine.

Krusher the 100 cam has a very stockish duration 274 vs 276(100cam.) The more lift, stock(.324) vs. 100(.400"), gives you the torque lost right back. It runs stronger than stock and is more suitable to a 1600ish engine than a stock cam. The barely increased duration then gives you a wee bit more top end so all around you are better off. I don't know if the cheater cam is more fuel efficient than the 100 but it could be. It is in between the stock cam and the 100.

Stock 250* at .050 214* lift at valve 0.334
W-100 276* at .050 236* lift at valve 0.421
Hope this helps,Mick.

Where did you get that a stock cam is 274 from? stock cam is 252

Cb has 4 cams in its fuel efficient range in the 260 range and 3 others in the 270 range of less than the engle.
Its not however in just the simple numbers its in the ramp angles also, but that's far to complicated to make a whole load of difference on a stock engine

I do not know if this helps..

Stock cams are 252 dur @20

I have a cam I sell that is 262dur @20 and 330 lift.. I like it in the bus's and mild engines with a stock Carb or kadrons..

What I see is 5 to 6 LB tq. and 3 to 4 HP gain and still pass's emissions easy

Art- Is that .330 lift at the cam? I'm looking for a good low rpm cam for a near stock motor in a dune buggy. Al

Ok so maybe I don't understand something here. Doesn't lift make torque too? Wouldn't the most torque be had by moderate duration and big lift? The 100 cam seems to fit that description any way compared to stock?

Its not just most tq, but at what rpm most tq is made, the added duration will move the tq peek higer in the rpm range.

Its nice to have TQ at a rpm range you use the most often.
