Hey I've found an L16 motor not far from here for a good price, it already has some work done to it. pistons, cam, head work etc.

I currently have an A15 in the ute and what I want to know is wether it is worth the effort to convert to an L16?

a quick google for hp stats found A15's make ~ 50hp and the L16's make ~ 90hp
Is that about right? (I am guessing those figures are with stock carbs exhaust etc)

I have had a quick skim through some posts on here about the L series conversions and how they are needing to modify cross members and sumps etc...
This necessary for the L16?

Do the A series g/box fit an L series block, if not, do you have to modify the tunnel to fit the (bigger?) box?

And one final thing, anybody got some ballpark figures on what an A15 with extractors and twin delo 45's would make compared to an L16 with extractors and twin delo 45's

Thanks
