HQ 500 c " Hurricane " Cams
Okay, just talked to Kevin at HQ great advice and reasonable prices, no sales pitch just advice.
Also talked to Zippers who's TMAT I like and TMAT support has been good. I currently run a D&D 2-1 and TMAT(thanks shooter64), have HD 103 jugs flat top pistons, normal to slightly agressive riding style, mostly highway, but also some city traffic in Miami.

Based on the lots of posts and experience of the people on this forum I will go with HQ. Hoping to get close to 100/100 hp/tq with flat curves.Going to attempt the install myself, do I need the pushrod conversion kit based on your experience?. Kevin also gave advice about alignmentr and filing off any burrs on tensioner, said this cam will be good if I do headwork later.

RE: HQ 500 c " Hurricane " Cams
That Zippers cam is not a bolt-in, so it will require a new valve spring package.............which they did not include in your quote. That would require you to remove your heads and have a shop install the new springs onto the valves.......which is more money and a lot more work.
The HQ cam is the same one I'm using in my build, and it's a great cam but I would think it might be a little "small" for a 103 build. In my 95" build listed in my signature, it's making about 100tq/97hp and the torque is very flat and wide.
Another one to consider is the Woods TW-6, it's a bolt-in cam and is very well known to produce flat torque curves.
The EZ-install pushrods make the whole job much easier, that way you don't have to remove the gas tank, rocker box covers, and rockers to change cams. I used the S/E EZ-install pushrods with great results...........they are $130 at your local dealer and you can get them cheaper with the X-mas sales coming up.

RE: HQ 500 c " Hurricane " Cams
MB Depending on how you want to approach this you may or may not need the adjustable pushrods and you definately don't NEED the adjustable pushrod covers but it will make your life much easier. I also just purchased the 500C cams and hope to have them by the end of the week and will install them next weekend hopefully.
On the pushrods you can use your stock ones (double check with Kevin) but will need to remove the rocker covers to do that. I personally chose to go with the HD set of adjustable pushrods as they include the rocker covers for $130 shipped from Surdyk. The part number is 17997-99A. I plan on cutting out my old pushrods and using the EZ install ones. This way I will not have to remove the tank and rocker covers.
Depending on your compression you may want to move up to a larger cam but as MUC said you will have to likely change your springs. I am installing this cam in a stock 96" motor. I was planning on doing the full HQ 103" build but this is saving me close to $2K and am hoping it will suffice for a year or two. I hate to rebuild a motor with 4500 miles on it.
Lastly not to hijack your thread can anyone confirm or deny needing new cam bearings for an 07 model. I understand the 88 motor required the bearings to be replaced as they were pressed in. Any other feedback on these cams. I did get a great reply from Boargaurd even though he wasn't estatic with the results.
Thanks and good luck.

Tom I ordered the easy install pushrods from HQ, got the gasket from HD, would like to know the answer to the bering question though, can have them pressed locally with no prob. I thought about the SE pushrods but jost ordered the HQ set while ordering. This is the cam recommended by HQ if and when I do head work I can upgrade the cam easily enough. Thanks for the input, will post with Q's and progress as I start the install.

RE: HQ 500 c " Hurricane " Cams
Personally, I prefer to replace the bearings whenever I swap cams. They are inexpensipiston and it's just kinda like insurance to me.
On the 07 ($08) motors, when you do the 103, you may want to consider a set of the pistons Doug (@) HQ had made to address the "down in the hole" scenario that is a result of the slightly shorter rods. If you use HD flatops, you'll be leaving some compression (AND power) on the table. The HQ's (specifically for the 07& later) motors will bring the piston back up flush with the top of the jugs.
If it were mine, I'd be sure to do that.... or at a bare minimum I'd get a set of the really thin head gaskets they have also had made for the same issue.
Setup right, you'll be more than happy with the results!

RE: HQ 500 c " Hurricane " Cams
Just got my build back from the dyno tune, Max HP= 97.44 Max Torque= 111.87 (Real Flat).
details are in my signature line, S&S Cams and Wiseco pistons, but the best part is the torque curve, check out the graph, pulls like a mother!
