Ford Windsor! Why, because they fit so easily. All you need is a bit of "set-back", the width fits right into 1200.

SBC or PP 13B.

Your secretly a ford man David ?

haha, it's no secret. I've got the Ford minitruck outside now (the one that sayz "Mazda" on the outside).

I sold my 5-litre mustang last winter for $1200.
I contemplated putting the engine in one of my 1200s, but in the end didn't want to fabricate a new rear diff to do the swap. I woulda put it in the Mazda (a bolt-in swap), but it wouldn't have passed the locally-required emissions test because the Mazda is newer.

After Datsun 1200s, I like certain Fords.

no offence but anybody can cut the firewall out to make an engine fit.try to do it with a standard engine bay.

I've gone for the 4AGZE with a turbo. Its lighter than a CA or SR, small, there are heeps of parts, they're cheep and you can get a lot of power out of them. Oh yea and they piss off all the "keep it nissan" guys. If money was no object I would like to get two 1.3 Hayabusa motors and get the conversion that lets you make them into a V8. 2.6ltr V8 with huge hp and 10,000rmp, how could you go wrong?!! (check out this link http://thekneeslider.com/archives/2005/02/09/hayabusa-v8-engine/ )Realisticly though the A15 is probably the best budget option and you don't need a huge amount of hp to make a 1200 go well.

go the z18 , old school and strong .

I like that Hyabusa V8. Lord help me, if I was rich...

A series all the way

I'm putting a CA in mine......

But - God how I'd love to see an RB20DET in there

you cant beat the original a-series just because of the size and reliability. i give my ute a flogging on most weekends and my mates cant believe how my car is still running. GO THE A-SERIES
