This is my problem - I built this 360, it goes ok but not as good as i had hoped, my 360 is an EQ headed Magnum engine with the 209/217 .5" lift cam, so then I thought well lets get big block power into it in a small block package, so I have been getting everything together, then I found the 40 over KB416 will not fit into a Magnum block, also when I got the block from the USA its perfect in the bores, so I need to get some KB416 STD from USA, by the time I get them to NZ they will owe me $1000NZD and no matter what you say a $1000NZD is still like $1000USD for you guys. Then my mopar friend in NZ said well to be honest you never really gave that 360 a very fair go did you, just bolted carb on set timing at what you thought, drove it and then say your not 100% happy, I them started researching and was looking at the Indy create motors and see with a similar set up (eq and indy heads similar) and with same cam, .5 points in comp they were knocking out 380HP so I was going to try and get the 360 running good, save up the money to get some more pistons. One thing that intrigues me is the blueprint motors compared to indy motors check this out. To me the blue print has higher spec cam, higher spec heads yet is down on power.
