Nelly 1 Posted November 28, 2007 Stop off at a mates garage tonight and had a couple of crossflows in the corner.. being nosey was having a look around them and notice something a bit wierd... with the engine number... I know if you see AA = 1300 and BA = 1600 but i have never seen DA.. thought it was a B without the center but scrapped it with a screw driver and i cant see any evidence of it being there... any body shed any light on it... Fake or real? Quote Share this post Link to post Share on other sites
MLI 7 Posted December 3, 2007 Have seen a couple of 681F 6015DA blocks myself, I reckon they are 1968-69 1600 xflows. Don't know the difference between the 6015BA and 6015DA though? Quote Share this post Link to post Share on other sites

Funnily enough, the recon 681F6015DA in your ebay link has the stronger square "uprated" main caps, like on the 1969-70 691M and 1971- 711M xflows? I thought the 681F xflows usually had the "non-uprated" round main caps? Or could that be the difference between the 681F6015DA and the 681F6015BA, i.e. the DA has square main caps, while the BA has round main caps? Or probably not, as the block "wouldn't know" one type of caps from the other... Quote Share this post Link to post Share on other sites

BTW, while on the subject of x-flow blocks, noticed how the mags always tell you to go for the uprated square main caps 711M blocks for tuning purposes? And they'll tell you all pre-1971 x-flows had the weaker round main caps, so avoid them. Well, the 1969-70 Mk2s had the 691M blocks, complete with square main caps and smaller (lighter) cam followers as well... Quote Share this post Link to post Share on other sites
