best big bore kit

[crashedpredator]

As the title sais just wondering who makes the absolute best kit, and how much a guy should plan on spending all in all. Also what kind of power increase should one expect?

[neandrathal]

im not sure who has the best but they run around 7-9 hundred for 560cc upgrade im going with max pm's 560cc big bore with ice cube head gonna be 640 and 199....................i hear it makes a good bit of difference

[crashedpredator]

Only 199 for a head? They are just porting the stock one then I take it?

[neandrathal]

the kit is 640 with a regular bored head but if you opt too turn that in an pay the extra then you can get the ice cube head

[crashedpredator]

I think I may try out a Rectifier before I decide to go all out on a big bore kit

[neandrathal]

i bought a procom one and it helped out a ton over the big gun you may need a jet kit too go with though.................have fun on the build

[crashedpredator]

As it sits right now theres a pure pipe no airbox K&N and its been jetted but im not sure what jets are in it

Friend mi an ask when you get it Ill let you know what you need cuz I need too rejet after adding the procom but u can feel the gain from that alone
