Yet another great video Graham, love a little xflow just as much as a pinto as an old skool Escort nut! Interesting to see the upgrades unfold as I was tempted to do the same with my old one, but went pinto power instead.
Great video, Love the crossflows, my Dad and I built a 1340 crossflow almost 30 years back, custom grind cam, big valve head, lightened conrods, overbore, big webers, exhaust and trick ignition system, etc . 8000 rpm no problem. Some low life stole the car. 😢
Great video. Looking forward to seeing how this little motor responds to some upgrades. I'd love to see all these upgrades done with the bcf2 and then repeated with something like a 234. Keep up the great vids.
Partially for the sake of engagement, what head would you recommend for a 71/72 2l block with pop-up pistons? My cammed 72 head threw a rocker... and chewed a lobe. There's water up top, so I want to try an injection head before I swap to the fresh turbo coupe motor in it garage. Just in case, until I'm ready for turbo power!
Basically the exact same setup of my last mk1 XR2 engine back in 1995. 1700 cc with the 1.3 pistons, I had a kent fast road cam, can't remember the # now, some nice porting and twin 40's. Still my favourite sounding engine I've ever owned, it kept pace with s1 and s2 RS turbos too.
Nothing special, tappet clearances as specified by Kent cams, points standard Ford settings plugs straight out the box so about 0.6mm, as this state of tune engine won’t be fussy
@@PenguinMotors Maybe too late to ask but would a bcf3 cam work on this same setup without machining pistons mk2 cortina block chambered head South Australian follower
Some engine needs retorque head bolts after few km and driving at low rpm(3000max) until then. What is the tips to torque the bolts in one session for this engine so you can dyno immediately after rebuild?
I listened to a short vid by an engine builder last month saying he fits Xflow rods "back to front" so that the oil squirter feeds the camshaft. Any thoughts?
plain bearings is pretty much 0.001" / inch of journal , did you say comp was 7.3:1 ? I thought it would be way higher with 1300 pistons and over bore. Running a cam in at 2500 rpm ? this is what the yanks believe, ( but they have rocks in their heads) low spring load, moly grease and matt finish on lobe and follower + low RPM does the job. there is almost nothing harder than chilled iron, you just have to treat it well for a good tough skin, a matt finish will hold lubricant where as a shiny surface not as well, for run in
comp, ok that makes sense, i should get my hearing checked. most load on lobe follower at idle, you better explain that one ! force is a function of acceleration and velocity the bigger the RPM, > the greater force > the greater the load The yanks believe in high RPM so the oil will flick off the crank and rods to lubricate the cam at run in F/ME Would not you make sure the pump is forcing lubricant in good quantity to all parts of the engine at start up ! I can see you will not agree, but what ever @@PenguinMotors
@@bobawatsit It isn't just the 'yanks' who believe in running the cam in at 2500 rpm, most, if not all, of the camshaft makers specify doing the same thing, and I'm guessing they would know, so there is that.
@bobawatsit its got nothing to do with flinging oil around! the answer is simple, at higher rpm the opening ramps on the cam give the valve train inertia, if the valve train is already accerating away form the cam then load over the nose is reduced, nearly every performace cam manufacturer recomends running in at high rpm
