This is on a 96". My point is that a bolt in cam with no headwork gives a wider powerband than 2000-2500 rpm. I did put in 030 head gaskets. Also, the Andrews 48 is designed for the 96" engine, but it is considered a similar cam to the 21, but optimized for the 96" engine. I'm running a Mastertune TTS.

This is in a 96" engine. My point is that you can get a much wider powerband with a bolt in cam than 2000-2500 rpm.

This result is considered good for this cam in a 96" engine. I didn't do headwork but I did put in 030 head gaskets. Probably the best thing I did is have Steve at GMR Performance dyno tune my Mastertune TTS. When it comes right down to it, one of the best performance mods you can do is get a dyno tune done by someone who really knows his stuff. Steve is a nationally recognized tuner, and was one of the beta testers for Andrews when they developed this cam, so he was able to squeeze the maximum performance out of it.

So to squeeze as much power out of a 88" TC without doing head work, whats the best recommendations?

I guess that depends on if you're looking for max hp or max tq. Like I said before, go to the Engine/Fuel/Intake/Exhaust forum in the tech section. If you do a search, there are plenty of "cam only" threads for the 88". If you just want to post the question that you posted here, you'll get plenty of knowledgeable advice there. It just takes a little longer than the general board because fewer people read and post there.

The Andrews 37 is an awesome cam for a stock 88" without headwork. I ran it for a couple of years before building the motor, eventually to a 117". I'm not saying there aren't other decent options, but will respectfully say that anyone who say's it is a poor choice is misinformed.

I went with 24Ns for my '04 RK's 95" build and I'm happy with the results. If I did the same build in a Softail or Dyna, I'd have gone with the 37s. If you want to go with the 21s in a 95" build, check out Joe Minton's article which can be found if you do a search. If you go out looking for cam advice, be specific about what you want to do NOW instead of "maybe in the future" because you'll be asking about two different cams. Woods, HeadQuarters and Crane cams are popular too. There are several cam threads over on HDTechTalk. BigBoyz has a compression calculator at their website that will help you with cam selection.

Differences of opinion are what make a horse race. The TW37's I ran in the 88" were, at least for me a great fit. The max numbers off the dyno runs, and more importantly the power curves support my opinion.

When I went to a 95" with worked heads, higher compression and a S&S G, I also changed the cams to Andrews TW55 to match the build, and moved the hp and tq numbers each over 100.
