95" Build
I am considering a 95" build on a '04 FXDWGI, with flat top pistons, 37G cams and Big Boyz Street ported heads. I am looking for lower end torque. I hardly ever get to 5800 RPM, but would like quicker "around town" performance. Any comments or suggestions, would be appreciated.

For low end torque I am going with the 26g's instead of 37g. Shoot a PM to Philm. He had 37g's and is selling them in the parts for sale section of the forum. He took them out and went with the 26g's. I also plan on doing a 95 build next year and will be going with the SE flattop 1550's

37's are great cams! I had them in my RG using BigBoyz heads & 95" jugs (bored @ BigBoyz), setup for 9.7:1 CR. Talk to Bean @ BigBoyz, he'll help ya get a config that works well for ya!

My build is a lot like the one you plan but I have Short Block Charlie head work. Be sure to get compression optimized for the cam you choose. For light bikes like Dynas I believe the 37G is THE cam! If you have a bunch of weight on your bike and always ride 2 up you might like the 26 or even 31 better.....

RE: 95" Build
Depending on your riding style both cam ares good. Being that we port in the area of 400+ sets of heads a year we see many many set ups. For a comp range of 9.5 the 26 will work well with good ported head look to see mid 80's for hp and low 90's for tq. Now the 37 in 9.7-9.8 range will make a bit better peak numbers but the peak numbers are not as important as the lower rpm range for the normal rider. Look in the 2000-3500 range and compare you will see the 26 will be a bit more perky in that range. Now if the bike is light the 37 works ok but go to a heavy bike two up riding/touring the 26 is a better bet .
Rate of acceleration is key here. Lets say they both make 90hp and 90 tq but one cam begins building tq at a earlier point. Which bike will accelerate faster?? The bike that can build tq faster
9 out of 10 times a bike that makes the tq at a lower rpm range will feel better for the every day rider and as well having a more usable tq range. Even when we build the 114 kits , that we set up the bagger's.... the 114 is completely different from a dyna of softail. Peak number wise they are very close but a heavy bike has vastly different needs than a like bike. Just because one guy loves a certain cam, does not mean that is a " perfect cam" there is a donkey cart full of other variables that can play for ....or against you in a complete package.

have a great night
