Its certainly not a bad idea. What do you want to achieve, and how wide is your wallet?

A rock-solid combo is a Wood 6, bore to 98", Good* set of heads.
Your power will JUMP, dramatically, and may very well be smoother also.
Good exhaust and tune. Great combination.

Good advice from Scott. If money is an issue, you can start with the cams, using a +4 degree cam gear, and do the cams for now, and do the rest of the motor later. It would be simpler and cheaper to do it all at once though.

Surprising no one asked you some basic questions first. Think about how you ride and what you want out of the cam in terms of tq - more low end, low to mid, mid to high... Do you ride 1up or 2up? How many miles are on your bike? Have you ever changed or checked the cam tensioners - you made need to consider that as well or gear drive or the newer HD hydraulic tensioner cam plate setup... Are you doing the work yourself? How much do you want to spend? Do you want lots of tq or a nice boost. The "right" cam alone will wake a 88" bike up nicely. And several cams will work great in a 88" and 95" motors. Also, be sure not to over cam or get mislead by high tq or hp numbers.

Not sayin to do this build. It just raises some good points and provide some info for you as you seem new to this cam stuff

If I were doing this I would recommend boring your 88 cylinders to a set of 95 pistons. I would run around 10.5.1 CR. I would suggest wood's TW6, 400, or 408 gear drive cams. I would also recommend changing the gearing in the primary. Get a good tuner and you should be good for 1 up, 2 up, or maybe even 3 up. Keep the wallet open because it's not going to be cheap. Just my 2cents.

I think you'll get a nice power boost and can live with it. Understand however that without headwork and a high-lift cam you will be, in a way, 1/2 done. But don't let that hold you back!

The reason I made the reccomendation that I had, was the fact that it is a combination that brings it on so soon, and has the ability to stay on as far as it does, makes it a such a versatile one, that from Dyna owners to the Bagger crowd, no one is left out in the cold.

Not necessarily true. There are cams out there, HQ0034 for example that will really wake up an otherwise stock bike.

I do agree that to get themost, headwork is where it is at, but a high lift cam is not a true necessity unless you are trying to wring the last hp outta the combination. There are many low to mediun lift cams out there that really do well - HQ 575 & 0034, Woods 6, Andrews 26, Zippers 575 and on and on. It is not neccessary to go beyond .600 lift IMO.

I've had the same sort of question. I ride stock 88 '05 Road Glide with power commander, screaming eagle air intake and V&H oval slip ons. I do a lot of 2 up riding, highway and mountain twisties. Have tour pack and usually carry a heavy load of luggage. I haven't noticed a lack of power but worry that I'm putting too much strain on the engine.
