It will bolt up, you will need to change radiator, hoses, throttle rod bracket, fan, fan support, not sure what belts you are going to need, and other stuff I am forgetting about. You will also be really disappointed in the power compared to a 420.

Good morning all.
Thanks Lavoy for the info.
Well, im still on the fence, partly… but leaning towards just doing a rebuild on the 420 engine. That will be down the road a bit as my dance card is full with priority projects at the compound :wink:
Lavoy, i will be in touch for more of your very much appreciated knowledge.
Thanks again to all on this platform!
Have a great day :D
