bigpaulo 239 Posted August 27, 2014 whats a log manifold? or a log engine? the pre crossflows are sometimes referred to as log motors. and ive heard the word log used to describe some modern manifolds. i tried googling it but nothing really answered my question (that i could understand anyway) Cheers!

steve mcqueen 1,796 Posted August 27, 2014 I have never heard of the pre crossy's being referd to as a 'log motor'. You maybe thinking of a 'long motor'? Thats the engine with the cylinder heard and maybe some acc's The 'short motor' being the engine with out the cylinder head. The log manifold would be the EFI manifold you find on XG/EB/ED Falcon, thats what i know as 'the log manifold' The EF/EL/AU etc have the BBM or broad band manifold as their EFI. Hope this helps. 1 XTREME KARTS XF reacted to this Share this post Link to post Share on other sites
bigpaulo 239 Posted August 27, 2014 hmmm... maybe im confused with the precrossys. i'll try find an example. why do they call that manifold a log manifold? when i googled it i noticed a lot of cars run log manifolds, not just fords. i thought maybe log stands for something? or perhaps its as simple as it looks like a log, lets call it a log? hahaha Share this post Link to post Share on other sites

bigpaulo 239 Posted August 27, 2014 http://www.ozfalcon.com.au/index.php?/topic/2032-xb-log-motor-rebuild-tips/ here we go! i knew id seen someone use pre crossflow and log motor in the same instance Share this post Link to post Share on other sites
gerg 10,871 Posted August 27, 2014 It can refer to either depending on the context. The early non-cross flow 6s which had the manifold cast into the head are called "log motors". EA-ED inlet manifolds are called log manifolds to differentiate these from the later Broadband EF-BF type. Share this post Link to post Share on other sites
SPArKy_Dave 8,826 Posted August 27, 2014 Log motor - (or more correctly, log HEAD motor) - the 1V pre-crossflow inline six's, which have the intake cast as a part of the cylinder head. Those head/intake combo's suit single barrel stromberg carbies - I like the strombergs, cause you can rebuild them for about $20.00. 4 Stevemack, Jonathan Mark Davidson, Outback Jack and 1 other reacted to this Share this post Link to post Share on other sites
SPArKy_Dave 8,826 Posted August 27, 2014 And as per gerg, EA-ED/XG-XH Multipoint injected manifolds, are referred to as 'Log Manifolds' due to their shape, where six equal length runners, branch out from a main intake 'log'. 4 XTREME KARTS XF, Outback Jack, Gav and 1 other reacted to this Share this post Link to post Share on other sites
wookie 45 Posted August 27, 2014 log motor is more of an american term for the pre crossflows isnt it? Share this post Link to post Share on other sites
bear351c 10,260 Posted August 27, 2014 Like Sparky Dave said, Inline 6 with inlet and head cast together. ( a "log" next to the head). That is my understanding, anyways. 1 XTREME KARTS XF reacted to this Share this post Link to post Share on other sites

GF0012-AUST 5 Posted October 6, 2014 Log manifolds (not motors) refer to the combined head and manifold on Australian 188 and 221's - It was an australian nickname for combined casts they're NOT an american block but come from a US baseline 200 I6 but with a raised deck (done by ford oz). the oz 188 and 221's replaced the US 170 and 200 "logs" before 250's came out it was common to lance the manifold off and make a separate one. I did this to a 221 that was in my XR, once you shaved the manifold off you could fit one off a gen 1 250, although most just dumped the original head for a 250 -2v. plus you could use 250 extractors with the head swap its called a log because the manifold looked like a log 1 bigpaulo reacted to this Share this post Link to post Share on other sites

n00bus m@x1mus 465 Posted October 6, 2014 I heard tell of the latest alloytechs in the omegas being log motors too, except on the exhaust side. So u have a single exhaust port at the side of the head and no option for a better flowing unit. 1 gerg reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted October 7, 2014 Yep I saw a pic of that V6 lump and thought "what the fuck? One exhaust port for 3 cylinders". Apparently it's to do with engine warm-up time (water jacket absorbs more heat) and it's only on the direct injection engines. Your useless bit of info for the day...
