    Oil viscosity for Aluminum Dart block engine

    Was the engine built by a third party, is it hyd roller or solid roller, could it have straight 30 viscosity. My go-to guy on cams hated synthetic oil on solid rollers as they 'skid' as the roller enters/leaves the lobe, hydraulics were OK as they maintain contact with the lobe. Rev kit is nice...

    Oil viscosity for Aluminum Dart block engine

    I'd be looking for a dry sump setup before getting excited about oil grade, at 370 cu in your gonna have some windage issues with that wet sump on the alloy block. Been there/done that, the main caps do a good job of dividing the wet oil pan into four seperate cavities. Ask the camshaft supplier...

    Is it worth putting in a 427 side oiler?

    Ive always had the idea that a MK2 or MK4 needed an FE, bit of a fluke recently I spotted an advert for a 391 T, actually turned out to be two of them. Heavy!, will need a couple of alloy intakes to offset that a bit, steel crank, brand new in 1972 as an industrial engine, negligable bore wear...

    Is it worth putting in a 427 side oiler?

    Transaxle vent/breather

    Great idea-your not the first!..... From what Iv read they did it on the MKIV- two versions, one was a torque converter & 2spd dog engagement trans. No big deal about inverting the auto. I have kept it in the back of my mind with my own transaxle. We ran a two speed Powrglide in a dirt oval...

    Transaxle vent/breather

    I assume when your talking inverted that the input shaft is lower than the output shafts and therefore the seal fitted at the input shaft is likey to be 'flooded' in use. Two options there, fit a seal that by design operates as a helix design and wipes excess back into the trans or convert the...

    Changes made to a MKII GT40 Superformance

    Its here in NZ, Bear in mind our rules around any alteration and initial registration of specialty cars has become a nightmare in recent times.

    Kar-Kraft assets purchased to yield more Mk IV

    My experience is only from run in, track testing of cars Ive been involved with. That is light throttle loads and careful shifting for 30 minutes, good chance to try and replicate street style driving. Required conentration to match RPM etc, I imagine the variables of traffic & dealing with them...

    Kar-Kraft assets purchased to yield more Mk IV

    Looks like internals are mainly Jerico based. Wonder what those cars are like to drive/shift on the street?

    Thanks for that, I can relate to damn near everything there, still have a copy of Wilsons book and done similar stuff to cars Ive been involved with, If I ever get this T44 done I'll be able to add it to the list.

    SPF GT40 MKII Ken Miles Livery Build

    I cant understand why people are obsessed with having a 427, its reputation precedes it and time done it no favours with corrosion . People then boring it further have only increased its self demolition. Why not simply find a 390 or even earlier 332/352 versions and apply a bit of recent...
