hello everyone im new to forum. i have a 11 fatbob that I had bored to 107, did stage II heads 1.900 intake and 1.630 exhaust. woods 555 cams and have pcv with at and thunderheader exhaust. do not know if se pro 50 mm will bolt up to stock heads the intake ports are stock. if it will work its the best bag for the buck.

 

well i found out today it won:\"t work.

 

Just curious. Why didn't it fit?

 

Yeah, I am not getting that, either. When I did the 96" to 103" conversion on my '07 Dyna I also installed the SE 50 mm TB and it bolted up fine. One thing though - I had to have the opening of the intake port on the head match up with the diameter of the TB.

 

when i had hillside do the heads they left them at stock diameter of 1.660,the diameter of the SE is 1.710 it would bolt up. but you would have a driveabilty problem. i have 7000 miles on build now and i am not going to tear the heads off again to sent out only to gain a few extra ponys.

 

My heads came back from P&P and I told the guy I was going with the SE 50 mm TB. Yet, I had pay another guy to open up the head intake opening to match the TB. While we were at it, we also smoothed out the intake runner on the TB - there was a "step."

 

i will remove the throttle body tomorrow and measure the intake ports with my dial indicator. to see if it stock or they did open it up some. if it is not i will most likly buy the correct tb to fit from hpi. they suggested the 55mm. not sure which injector to use the 4.9 or 5.3

 

I got ya. Kinda what I figured u meant but I was thinking maybe there was some other fittment issue. Just sent mine off to Hpi today getting 58 elliptical back
