Putting my first pan engine together, not factory, but still a Panhead. Here is what I have so far:
S&S generator cases 65-69 style
STD dual plug heads,stock rockers and blocks
T&O 4.5" stroke wheels with S&S rods and new Jims shafts
Stock 74" cylinders bored .010 over
I started buying these parts here and their over the past year, I also have several of the small parts to complete the motor. I have almost made up my mind on an Andrews B cam but am looking for your suggestions on the cam and lifter choices. I know of the velva touch setups that come complete with lifters, blocks, pushrods etc, their is also Vulcan Engineering that sells a complete kit also. Do any of you guys have any other suggestions on the cam and lifters, blocks, pushrods? Engine is going in a lightweight bobber style bike. Looking for arm stretching low to mid range in the cam. Thanks in advance. Oh, would love to find a set of stainless Pan covers I could polish up also.

Our builds sure aren't very far off, I wanted to do the roller tips on my rockers also but kept telling myself, Damn that $400 bucks could buy my lifter and blocks. I will check the S&S 514 cam. Thanks

Try $500. The 514 I've never used myself but it was highly recommended by many friends and builders. I have many build-up pictures if your interested. George the guy building the motor is slow as hell but, brilliant and very detailed orientated. Good luck with your build.

For a street engine, I think the B cam has too much duration. It is true that once you get up into the power band of the B it really pulls, you have to ask yourself how often you want to turn it that hard.

I have two pan motors with AB in them and I am very happy with their performance. My '48 has STD heads on it with a mikuni 45, the '60 has stock heads with a super E on it. Both engines are 8.5 to 1 with stock stroke. In general the extra stroke you have allows more cam, but also accelerates slower.

I built an 80 inch shovel with a B cam in it years ago (before I owned the pans) it was reccomended by the builder. His claim was it feels like you found another gear.
I removed the B cam and installed a competition cams cam with duration between the A and B, the bike was much more fun to ride. Better torque and hauled my OL much easier.

I use Jims solid lifters and vulcan pushrods

Thanks hd74 for the info. And after talking this morning with Gary at Andrews, he basically told me the same thing you did wahoo, the B cam is probably a little off for where im wanting my power. He advised me to use the A2 grind and keep the comp to 8.5-9.0:1.

Like hd74 I like the Jims lifters., been running them for years and they're great. Just remember to check the bearings in them when you start getting some real mileage on them.

For street motors I like the duration in the low 40's. There are already plenty of over cammed motors running around out there. I need to do one more side project and I'll have enough bucks to order a set of stainless rocker covers myself. I see that V-Twin offers them, the price isn't too bad.

I like low compression bikes with an appropriate cam for kicker bikes. An Andrews #2 and 7.5:1 with your set up would be a nice running bike.

The benefits are stock or OEM replacement components will live long with that and regular gas is a bonus. Depends on what the end goal is with the bike. Low compression bikes tend to live long too.

No wahoo, it is the A2 specs are 19/43. 242 .470. Only diff I see between it and the AB. Is that the valve opens at 21 instead of 19 and duration is 244 compared to 242.

Lobe centers and separation angle are very different between those cams. That changes the power delivery of a cam considerably.

Those Leineweber cams look interesting, but the real steep lobe ramps look like they would be kinda tough on the valve train. Interesting design though, if power is more of a priority than longevity.

Regards,
Geo.

I like the Crane 296A cam. Has served me well for 90K+ miles. I have the lifter blocks, lifters and adjustable pushrods from Flo Headworks. They also have 90K+ miles on them. They are basically modified EVO lifters and lifter blocks. Makes for a bullet proof valve train.
