brassman wants to know Dino or Syn?
I would go with the 251 cams ...... you will get a little noise out of the top end but man .......those will pull hard 3000 rpm- up as far as you can hold on. Had a set in a 95"bagger with an e-pipe and Red's heads and it was a hand full mid to top end , bottom end was also strong with the pipe and compression. I am sure you will not be disappointed as you have a good pipe too

The Wiseco 10.5 pistons I used in my 95" were 14cc.

My delima is... i have 3 cam sets on the bench, a TW37B, an SE-251, and an SE-257.

Not sure which will be the best for my build?? Sometimes i just cruise, and sometimes i ride hard, im looking to get some respectable #'s from this build.

Also, the cam card with the 257 shows .560 lift, everythng else i have read shows the 257 to be .569 lift, maybe i have an older grind??

Thanks
You always have to match the Cam Profile to what your Heads are flowing! heavy port work doesnt mean anything unless it was done correctly

I had a 95" with 257 cams, heads, propipe, and got 100/100 4th gear on a stingy dyno. But, I had 10.5/1 static and 195lbs compression. You have 11.65 static and would get 220 lbs compression. I had a ping problem, but I think your engine setup would have way to much comp for any of your cams. This is assuming my BigBoyz calculations for your engine are correct.

My heads were done a few years back by mutant motors, I honestly do not remember the flow #s without the sheet. I do know they were told to go all out with them for big street hp. The intake runners are around 1.880 if I recall, they are an exact match to the ported s&s intake I have, that also has some type of "divider" along the back of it?

Would a .40 gasket be better?

The compression on mine was a little higher than I wanted with a .030" gasket so I milled the piston dome to get the desired compression ratio. I'd rather do that than compromise the squish.

This is just an opinion, so you can add this to all other opinions.
Let's say you decided to use the 37 cams and these cams run best at 9.8 static. Considering your at 11.65 comp, in order to get down to 9.8 (if if it were my bike) this is what I would do.
I'd buy flatop pistons, which would give you a 9.8 static with your current setup. But, If you have your heart set on using the H/C pistons, then to get 9.8 comp - here's one solution.
1. You have to open the head up and take out 15cc per head to be able to use a .030 head gasket. Your H/C piston has a +14 piston volume.
Another solution would be to select a cam that needs that kind of compression. One that has a relatively late intake closing. Either solution , to me, is just putting a bandaid on the main problem, to much comp. JUst my 2cent opinion. By the way, what cams are running in this engine now?

Yes, at least a 100+ if the heads flow worth a sh!t. No need for rollers if you stay under .600 lift (my opinion). To use the 251 you would need to open up the chambers some. You could remove about 9cc and that would give you close to 10.5 static and that's what the 251 likes in a 95". Or have the pistons machined down.

I don't have any experience with the 257, looks like to much duration for a 95" street motor.

Use a .040 gasket and the 257
With the timing events on that cam it will rock and roll at 11.5
Good tune on the G with adjustable ignition , it will be a beast.

Thanks Fella's, This morning i went ahead and installed the 251's, heat cycled the motor SEVERAL times, then went for a ride this afternoon, quite impressive that the little motor will roast the back tire just rolling on the thottle in 1st, and 2cnd.
but im quite sure theres a bit more to be had, maybe toss this SE ignition???
....and the 251's are a bit noisy after the oil warms up

I personally don't like se ignitions. All of them I have seen are not adjustable. Get your self a daytone twin tec and then u can adjust it as needed.
Softail=burnout. I smoked a well built softail with nitrous the other day, all he could do was spin his tire as I wheelied away on my dyna.

It will make 112-115hp if everything else is right.

I'm going to try that cam next, it's not that big of a job to pull the cams, just had the 257s and bearings pressed in an extra cam plate i have, I know the cams are a little lower on lift, but have to try em.
