i am having a hard time finding the 2.5GM litre engine for the Robert Davis adaptation kit up here in Canada so I may possibly need to just do up my own 2.25 rover engine. I will look further into finding the right 2.5 GM but for some reason wreckers and engine rebuild shops don't have the type I need.
So............ an 8:1 head will help with horse power but much else? I know it already has a rebuilt Solex so that is a little better, reground cam to the specs of a 2.5 litre rover and K&N air filter I have heard helps but anything else?
Any advice on the 2.25 would be great.
