well have just had a quick read, so hope I did not miss any points, and hope me not repeating any thing!!
yes the 3.0L are great, however there is an hidden gem, that very few people know about, another one of those where the manufacturer got it all wrong for various reasons!!!
so let me give my 10c worth here!!
self have the Ford 3.4 V6 and have considered going back to the 3.0L till I learned few things!!
why is the 3.4L not stronger:
well when Ford was busy developing the motor they had a choice of cams from a cam manufacturer, Ford SA took the cam that produced the less amount of power and torque, one of the reasons being that the gearbox suppliers were not happy to take the risk of the extra power!!
where the those boxes are actually very strong!! as strong as a toyota box, yes!!
and have played with toyota gearboxes before!!! done a few conversions!!
yes also true that some of the 3.4l had a heat issue, yes also true, my 3.4 does run hotter then what the 3.0 did, it is a bigger motor and it does produce more power, it has to produce more heat!!
and my 3.4 does have a heat issue, although only when towing 1.6 tons coming back from he coast, in traffic on the hottest summer day, bumper to bumper crawling on the highway, stayed perfectly cool!! yes my 3.4 does still have a issue somewhere!!
that is part of the reason why I am here, to get plenty info to make a proper decision about the Lexus V8
now back on the 3.4, with a nice cam, nothing radical, with a nice set of heads, and it will shine just like any other V6 of similar size!! hence the rev limit of 5400rpm on those motors
how do I know all this
have met and am in regular contact with one of the guys involved in the developing of the 3.4 V6!!
and a good friend's brother works in the same department and has confirmed the info!!
busy convincing myself out of the Lexus V8 conversion!!!! eish!!!
any case the 3.4 had Hydraulic lifters, those did not last for ever, however my one has taken a beeting!!
as for the engine mountings, have you guys ever tried the Sierra mountings they have a fluid inside, and can take a hammering, ask me!!
sadly these motors were not EFI, and the EFI manifolds are as scarce as chicken teeth!!
however the original carburetor manifolds can be converted into EFI manifolds, there is engineering work to it!!
not just bolt on!!
well think I have said enough for now!!!
