This is a really tough one to call your blazing a trail I have not seen a dynosheet for. In a 103 with raised port head and a 103 properly tuned the cam / motor combo from Kury was making 126/119 give or take a couple on the hp side.
In this case with a 110 I havent really seen anyone use this cam, so it is an unknown to me. The porting / polishing there is no numbers for or information about what was done. You say 10.5 to 1 compression, but while it is a number there is other data. Flows, valvesizes, CC of head etc.
I would hope you get at least 1.15 to 1.20 on the numbers. If you had used the 24d I would expect somewhere in the neighborhood of 115-122/118-124 based on good porting/valve job, velocity of the head etc.

thank you for your reply, i had a 24d in it before and made about 112 and 118, my tuner liked the 46g, i also like it, no valve train noise ,always looking for a little bit more :apple:

In a 113" I made 126hp/121tq with the 46G, heads did not have a raised port. Supertrapp 2X1, compression set at 10.6:1 & 55mm throttle body. I also ran a 46G in a 95" with a Thunderheader, more bottom with a Supertrapp, but with a good tune it will still run good with the TH.

thank you for the info, 126 and 121 are very good in my opinion, i hope i can come within 3 or 4 hp and tq. of that ;D

Who did your heads? You can PM me if you prefer.

Not sure what intake to exhaust ratio his heads are. 75-80 % is good with those cams. Either way, I don't worry about numbers. Those cams have a linear power band, and get you upstairs before you feel it.
