440 kits???

[pigpin]

anybody from NC running a 440 kit??? I already have a ton of problems out of the 426 kit, and instead of rebuilding it, i was thinking of goin all the way to the 440 with little lower compression to run it on pump gas. are these set ups good for the trail, i never race it, just ride it. or for the little bit of power advantage i gain should i just go back stock bore and higher compression piston. i just want my 400 turn key reliable and fun, not turn wrench aggervating and broke 70% of the time.

thanks for any and all input

13:1 is high. if you lower it to 11:1 or 12.5:1 itll be more reliable. 11:1 on the 440 is good

11:1 on mine runs awesome, However like I said in your other post in Powertrain forum, If your current 400 engine/piston/sleeve is running good keep it stock, thats your best bet for reliability.

i would also put in HD head studs. the 440 will rip your stockers out

[pigpin]

no, its not stock, 426 with 13:1.... where and how much can i find some of these head studs???

thanks

Look into a stroker from www.powroll.com, as reliable as a stocker and fast.

www.GTthunder.com

thanks fellas... so back to my worries of running hot. I mean how much can a couple MM difference literaly make?? anyone having issues with this?

my 440 doesnt over heat. Ive ridden in 85F weather for hours and its fine. but i also shut it off for 5 min every once in awile

[pigpin]

sitting for 5 minutes probly wont cool much, actualy riding the qaud at a decent rate of speed will cool better then sitting still off after being ran a while i would think. but im not talking at wot screaming, just a cruize at a decent rpm to keep air moving over the heat sinks.

you could also put on a cbr 1100 oil cooler they are about 2 times the size of the stock one and with just some oil line mods it will hook right up


i can post some pics if you want to see

I've also done the CBR1100 oil cooler mod and it works well. I'm surprised to see that I'm not the only one that has done it.

j450rking--I'm curious, can you post pics--I want to see how you mounted yours up.
