I was chating with a guy at bike nite, and he said that the jugs and heads off a twin cam would fit an evo motor......Any input would be appreciated

 

I dont think they will, Im positive the bore and stroke are plenty different!

however, the rockers, are the same and valve springs on the pre 05s.

 

Nope,not a bolt on deal but it can be done just like the old Shovester with some special parts and machining.

 

I had a web site that explained how to do that but I lost it. if I remember you need to bore the evo cases to fit the twin cam jugs using the 95 in pistons with the stock evo sroke would get you 100 cubis inches. they also said you have to mix and match the pushrods to get them to fit.if you have alot of odd and end parts with no home it would be fun to do.might not be cheap, but you'll get some strange comments as to what motor is that?.,,,,

 

S&S makes cases that allow you install a Twin Cam motor in an Evo frame. You would use the bottom end components from the TwinCam engine as well. Might be cheaper than machining the Evo bottom end to accept the Twin Cam jugs.

 

I bought a couple of left over cases from S&S for this if anybody is looking for them, I believe they have been discontinued.

 

I'm running a 95" S&S Tc on an evo mount in my 98 heritage. Works good.

 

The spacing of the cylinder studs on the TC are different then the EVO so the jugs and heads will not bolt on.Will not match the case.
