Love the kind of understated mod. Perfect for the classic enthusiast who wants to keep everything close to original.

Good job ! Grinding away the edges and flushing the inletports of the manifold alone , does allreddy miracles ! You can hear nr 2 run more " round " beqause of better breathing . I have done this in the 80s to the in and outletmanifold of my Alfa 2 liter engine , and with its twin Webers won about 10 BHP , just by this simple grinding alone . Old school tuning , lovely !!!!

Fascinating stuff! Similar to what I am doing with mine, just not as googly eyed. I have an early block and heads and have done the following: -sourced 10.5:1 pistons -machined the block and heads 10 thou -heavily ported the heads and manifold including perfectly matched ports, radiused and matched ports to seats etc. -shortened modified guides fitted with modern stem seals and 3 angle seats at 45°-45° for seat to valve. -480thou lift cam after the 1.6 rocker ratio. -reground late EFI SD1 crank, forged rods and ARP studs in bottom end. I'm hoping it will be a barrel of laughs. Will be advancing the cam 4° to bring the power in sooner, as I don't want to be revving the proverbial faecal matter out of it. I also made a "stealth" baffled sump for my P6 which I made a video of. But I'm not good at KZreading. Nice to see I'm not the only nut job who wants to claim with a straight face that it's perfectly stock.

Good stuff 👍

Good gain Graham , very rarely did i get 150 out of a stock engine i use to do a lot with the 4x4 brigade. Weber at the time did a replacement 4 barrel bit like the Holley it came in a kit with a Offenhauser inlet and a big round K&N as you know this totally transformed them and with some nice manifolds on sometimes you would see a good 30hp gain and similar with torque ... then they started snapping half shafts lol . But id say your on the money with that gain. Just think with a good head job and bigger valves and a 270 cam and manifolds u might see 200+ ...

Hope your camera man had his ear defenders on when recording that second run and leaning over the top of the engine like that , 😂 another great video 👍🏻

V8 Rovers are not too bad on noise, When dyno-ing them i dont tend to wear ear defenders even if i do pulls with the cell door open. High rpm pintos on sidedrafts are another matter!

loving the v8 vids ,When fitting the 10 bolt heads which head gasket did you use tin or composite?

Used composite to avoid changing the compression ratio, but could of used tin to gain some

Did you put new crank bearings or one of those fancy duplex chains in Graham?

Hi, love your informative channel. I have an early 3.5 in a TR/7, have run it in sprints and hill climbs for 12 years and was always reliable. installed new rings and bearings and timing chain and now having problems chewing out the cam drive gear this has me stumped can you help me. Pump is free moving, cam the same, early, no retaining collar. Thank you. Michael Simington.

In the old days that used to be fairly common fail. it was usually put down to revving the engine hard before it was fully warmed up. It used to be common to add an extra oil feed to spray oil directly at the distributor gear. there's also a couple of spots where you can drill holes in the block which improves oil flow into the timing case. Have you got the gear on the cam the right way round? it fits both ways but one way it lubricates better due to the groove in it. as with a lot of things, im hearing that modern gears are poor quality, search out new old stock, or good old ones. Have you changed your distributor? if so check that the gear end of the distributor shaft has some up and down end float, if its got none the gears may not centre themselves correctly and will wear faster than they should, there a similar thing happening in the world of ford pintos with certain brands of distributors.

@@PenguinMotors Thank you for your helpful information, will make al mods and keep fingers crossed. Had this problem with another rover and only way i could fix was to extend keyway on crank, fit crank oil pump and timing case cover. Thank's again.

I took a 4.6 out of a range rover and rebuilt it using 3.5 front cover etc, edelbrock carb/manifold, distributer. 3.9 cam. Care to hazard a guess at power?

I have a SD1 standard v8 what is a rough cost from tuning it up to around 200bhp?

@PenguinMotors

that depends kind of depends on how healthy it is. but if its healthy engine then you went up a stage from the very mild cam i put into this and with some air filtration improvements then you should be over 180bhp, chuck a 4 barrel carb on it and you should be past 200bhp
