Predator 420 cam questions

[shadowfocus603]

I'm in the process of sourcing parts for a 420 swap into my Manco 906C cart and have a couple questions on cams. Which would be better for an offroad cart the .275 or the .308? I am looking at the stage 2 kit from GoPowersports as seen here 420cc Predator Stage 2 Performance Kit - GoPowerSports.com and am curious which would work best in a heavy offroad cart that sees a fair amount of WOT.
Cart in question. My son is 5'6".

For 23.00 more you can buy a complete Vegas carts 460. ready to run out of the box. I have 2 of them & really like em. vegas carts are good to deal with also.

For the price, I definitely would not buy the GPS kit. I think they're a little overpriced but that's another discussion.

The Vegas Carts is a good option.

Look around at https://www.nrracing.com/ . I like them better than GPS. They give more details on what they're selling to you.

Also, I hope you're using a 40 series CVT. A 30 series would never hold up to a 420 or 460.

I will be going with a 40 series yeah. I will look at Vegas karts and see what's up.

I had a 40 series on my 460 & it would not hold the HP. went with a 780R & a 90D works good !

I use a 40 series on my open mod 390 on nitrous and it works perfect. you do have to change the driver weights and springs to modify for launch and you need to throw the belt that comes with them in the weeds and buy a Kevlar belt from beltpalace.com and it will hold what you throw at it.
