yes it can be done, but it requires pretty serious cutting of the crank..

How it that possible? It would have the same stroke as a 360, but with slightly smaller bores and smaller head ports.mopar65pa said:I have heard that a 318 will put out some serious power that way. More so than a built 360.![]()
Now that's what I'm talkin' bout!muddSlinger3187 said:that speedomotive website was quite interesting it sounds like it would be a bad little motor jumping a 318 to a 390 i think thats quite a bit of a jump way more power than a 360 if u ask me, cuz i mean u stroke a 360 and its a 408 not as much gain as a 318 to a 390. and ya scan that sucker if you dont mind id love to build one and i lookin for all the info to do it cuz i got sevral 318 blocks and a 360 crank layin around
Thanks

1st a 4" crank in a 18 is 384 not 390 it becomes 390 after it's bored 30, now lets think about how you figure the 18 is benefitting more the 18 starts out as a 3.91 bore, the 60 starts out as a 4.00 bore, the 18 starts with a 3.31 stroke the 60 starts with a 3.58 stroke.muddSlinger3187 said:i think thats quite a bit of a jump way more power than a 360 if u ask me, cuz i mean u stroke a 360 and its a 408 not as much gain as a 318 to a 390. and ya scan that sucker if you dont mind id love to build one and i lookin for all the info to do it cuz i got sevral 318 blocks and a 360 crank layin around
