<p style="margin: 0px 5px 0px 0px;"><span style="font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000;"> There are not many differences on the blocks from</span><span style="font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000;"> 29D to 29F engines. Not sure if the 29D block still had the opening for the manual fuel pump. On 29E and F it is no hole anymore in the casting.</span><span style="font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000;"><br /></span></p>
<p style="margin: 0px 5px 0px 0px;"><span style="font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000;">There was an extra bracket fitted against chain slack from 29E engines onwards (perhaps 29D engines already had the holes for the bolts, not sure about this).</span></p>
<p style="margin: 0px 5px 0px 0px;"><span style="font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000;">All other changes are not to the bare blocks as far as I know. Inlet/exhaust manifolds, carbs, crankshaft pulley & damper, generator, <br /></span></p>
<p style="margin: 0px 5px 0px 0px;"><span style="font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000;">On 29K engines the block is different as David Nock mentioned.<br /></span></p>

<p class="MsoNormal" style="margin: 0px 5px 0px 0px;"><span style="font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000;">We have had a discussion about pistons etc recently, but can anybody enlighten me as to the difference between the 29D block and E & F varieties, apart from camshafts which are interchangeable anyway?</span></p>
<p class="MsoNormal" style="margin: 0px 5px 0px 0px;"><span style="font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000;">I have been informed that the earlier crankshafts are more desirable owing to a higher steel content than the later ones.</span></p>
<p class="MsoNormal" style="margin: 0px 5px 0px 0px;"><span style="font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000;">Or is it just BMC sticking another plate to designate the different model car it was fitted to?</span></p>
