Certainly someone has done this? I building my 05 450, its getting a 14 to 1 piston, stage 2 hot cam, ported and polished head, full HMF exhaust, and a rev box. Im wondering what this power is going to be like, and am I forgeting anything.........? Let me know please.

I'm getting 47-48 on knobbies with my mods listed below, at the present time. I am going to be running on Mixxers dyno in the next few months, and then I'll know more. You should be close to this though.

Do a search under MIXXER PORTED HEAD, HOW MUCH DID IT GIVE ME in the engine section, and you'll see my graphs. Like I said though, I need to run on Mixxers machine, to get a comparison between the 2 dyno's.

what rev box? they are a waste of money. make sure you get all your gaskets, piston and rings before you tear it down and also get you 3 extra filters and quarts of oil for the break in.

you also need to find the fuel you are going to run. i use vp c12 others use vp110 and there are some other choices just not familier. these are leaded fuels!!! I would also run an open air box or box with the bigest filter and no lid.

later

Yes Yes, open box big filter. I am wondering about fuel....... carb, and needle. Should they be changed? If so to? FCR carb? HRC needle? WILL THE STOCK CARB KEEP UP??????
