Difference between 736 and 738

[Carlv8415]

May have been covered before but I couldn't find an exact answer.

From what I have worked out they use the same block just have different inlets? So if I had a 736 engine it would go in a 182 if I used all my original parts off the old 738? Is that correct.

Just you see just the block advertised by 736 or 738 so wasn't sure if they was different.

Thanks

From what I can tell its only the decanter and rear mounting of the inlet manifold which is different.

rocker cover, breather plate, inlet plenum

rocker cover, breather plate, inlet plenum

So all stuff that can be swapped over

no, rocker cover it matched to the head

no, rocker cover it matched to the head

Any noticeable difference performance wise with different rocker cover

The rocker cover itself you cannot change to a different head. You can change the breather plates that bolt to the top however.

On my engine I have noticed there is an egg shape hole on the bottom of the inlet but on the rocker cover its looks like a hole should be there but it's just a flat plate. So the rocker cover breather is blanked off basically.

Yeh that's the bit that's transferred.

you cannot fit a 738 breather plate to a 736/732/730 head though

My 182 has the one on the right...

 

[Fred@BTM]

therefore you cannot fit a 736 engine without "bodging"

 

[Dan519]

well you can, but it's a bit pointless buying carbon canister vac pipes IMO, when a bung will do

 

[Dan@SJM]

I have metal bungs that fit the 172 CC pipe perfectly for that reason. My Monaco is running no cc actually thinking about it.
