Would love to see footage of the actual drag race!

With Cosworth twin cam cylinder head fuel injected and turbocharged will return 350 to 500 horse power

Always great watching your vids.thax for teaching and sharing your knowledge and experience.

Have you managed to do any test with the Kent RL30 camshaft? If so would it give similar gains to these camshafts?

This all looks like a really good reason to just LS swap it…

hope you’ve cleaned your workshop

Were the early (rope rear mains) ones not higher compression and 5 star fuel only? 178bhp?

I'm glad I'm not the only one who struggles to find where I've left tools!

Hello.i have a pinto head that skimmed 1.5mm what thickness gasket do I need for a compression ratio of 11.

Humm practice says different

I built a 1906 cc engine AX block 85 mm JE pistons Laystall crank 84 mm stroke. - 12 bolt. Kent vernier timing Kent 254 Hot rod cam wasted beteeen lobes. Carillo rods ARP head stud kit 1.5 std ratio roller rockers Dellorto DHLA 45s Aldon Race Dizzy Mass Racing exhaust manifold. Ported head big valve but not the largest built it 10 yrs ago memory a bit fuzzy but she bumps out 175 hp /150 ft lbs

balistic in a lightweight car you say? interesting

How's part 3 coming along?

Might be out of your scope Graham, but if I had the money one thing I'd love to test is two 'identical engines' both blueprinted, one to the worst end of the specs, one to the best. Maybe pick an engine currently used in some bog standard engine race series (like Formula Ford did).

Great content on this engine builder, that engine is going to be first class for a street car, lucky owner has someone competent building him a good engine.

Back in 86 I was rallying an SD1 that we fitted with 2inch SU’s off a scrapyard Jag, went fairly well!!

Does this engine use a roller cam or standard style. And what is your opinion on going to the effort of roller cam conversion? Cheers

Hello, can you tell me what the cost of the camshaft is on this engine?

Hello, can you tell me what the cost of the camshaft is on this engine?

just something to check out. There is a company in California U.S.A named Esslinger engineering that makes all kinds of race parts for the 2.3 Lina engine. I saw a RUclips on a site from power nation. It is building a 2.3 4cyl lima for dirt. It made 268 HP 7 211 Torque. With a 2 bbl. Holley carb.

Is a Rover v8 like the 3,5 liter expensive in rebuild? parts? How easy or hard to find today. Oh i forgot there was this Ford Cortina ( Steve Green? ) on the dragstrip many years ago that had a very powerfull to 5 liters in the end. I wonder how much developement went in there, and why stick to that concept? ( by the way happy new year )

I knew the 36mm chokes were too small. I prefer longer intake manifolds,, more torque the shorter ones with the Mikunis had an advantage. Some tuning with those however may make more.

How accurate were Ford Rocker arm ratios ? , If each rocker ratio was different due to production machining then the motor would loose Torque, This was the case with Austin Mini Cooper Forged factory rockers, The ratio 's varied from rocker to rocker causing a power loss due to Cam timing not being the same on each lobe at the Valve. Graham Russell Pointed this out In Australia. He would over come some of the power robbing by working out how much to alter the Valve Tappet clearances to make the valve timing more similar to each other.

Vulcan used 40dfi5 iirc

Did the USA use the 2.0 Pinto in their Ford Pinto car?

Great video and engine Would you conciser it worth going itb’s on a m20b23 323i I thinking more power. A cleaner engine bay. Better economy. Is that possible within a reasonable budget really. Thanks

With Edelbrock carbs, much of the tuning is done with the metering rods, the same as SU's or Stromberg CD carbs. Metering rods allow you to richen or lean low or high RPM separately. Requires getting the tuning kit for the carb model.

Sounds very good 🙂

I managed to get 176 hp from a pinto.Twin 45 dellorto's 285 cam, 421 manifold, larger valves and smaller intake ports.The ports are too big on these as standard. Making them bigger and polishing them is going the wrong way. Had a 5 speed gearbox going to an estate rear diff. The normal 2 litre diff was geared for something silly like 160 mph in 5th. Pattern clutches would just slip all the time. Using a genuine ford clutch could just manage. Started out as a 1.6 4 speed Sierra. 2 litre and cam made a big difference. Boring to 2.1 seemed to do nothing at all. Left it looking standard and used to have fun with GTi's etc. Was a fairly fast car 40 years ago. An ordinary modern 2 litre diesel would be about the same these days. At 63 I now have a litre motorbike, glad I did not have that when I was younger. I would have been lucky to last a week.

hi penguin motors eny chance you can take my pinto and sort it out its in my rs2000

Someone needs to make a ir intake for v8s for those carbs . 8 carbs long runners, big torque.

For every day driving the SU's blows the Edelbrock away.

Great video mate.

Here in Australia,my Chrysler 5.2L or 318 is a mild engine,actually being a 1980 engine it was quite choked up from factory with all the emissions garbage on it and I suspect the heads are not very free flowing either? However it now runs a mild cam with an Edelbrock intake and the same carburettor you ran,a 500 Edelbrock. It was tuned professionally and I must say that it works beautifully! It made 210 hp at the wheels and is quite responsive. Great carbs

It's strange, all the performance guys in the US go for Holleys on their V8s, Edelbrock is a good daily driver carb, but nothing special. In the UK it seems to be Edelbrock is the performance 4 barrel to have, I suspect persuading UK buyers that Edelbrock carbs are the best 4 barrel is down to marketing.

This 4.6 sounds beautiful ❤

What happens with the crank? Is it shorter? As far as i know the cam will need to be longer for the distributor

Good God, people still p#ssing around with those things! I was the machinist/engine builder for Janspeed when the Rover V8 was a thing and did the Le Mans project engine as well as the Leyland race engines. The port size was death on the heads and we just ripped them out with a big end mill but the rest couldn't be helped, the only way we could get real power was dry-sumping with a doubled pressure side oil pump and for aspirated engines a billet flat crank (which took me a month of overtime to make). With TH injection we could pull over 450hp from the 3.5 block but for Le Mans we went to twin turbo and 4.7l flat crank and could get over 600hp on the dyno (and destroy gearboxes). Basically thirty years later you could get better power from any Japanese 2l engine.

I love to watch honest comparison videos. I. don't know how much time you can or do spend optimising each set up. I would like to see 1 on OE cast exhaust manifolds (pintos had a few different 1s) vs the most common 4 branch.

How much of this difference is due to the differing intake manifold design? Guess we'll never know. I suspect the low speed throttle response would be better with the SUs and would be inclined to suggest the 4 BBL for hooligan use.

Isnt a 500 Edebrock too big a carb for an RV8? Edelbrock make a 390.

My brother stuffed a Buick 215 in his Austin A35. 11.5:1 and a long cam. Basically undrivable with 290hp. But it sounds awesome.

It's just great to listen to a guy who just says it how it is, like walking into a local friendly garage or chatting to a bloke down the pub back in the day that is becoming a rare thing now passing on there knowledge and experience I've thought about contacting them for a build I'm doing but it's the geographical distance for me...shame I'd be made up if he could work on my build..top guy 👍

Closer than it looks. The SUs have the edge up to 4k, and quite a handy lead from 2500 to 3500. I think in real world street use - especially with an auto - the SUs would probably be a little quicker. By the time the 4bbl got to 4k it would be behind the SU car and would need some distance for the top end advantage to get it back out in front.

It wanted to rev out because the last test had a carburetor with no air cleaner. The blank flow without air cleaner on the HIF 6 according to David Vizard flows 245 cfm each, or 490 cfm, same as the HD8 SUs. The stock intake and SU's are good ones. Your stock P6 intake wasn't clear of all it's shackles. Rover Really knew what they were doing.The huge, fat torque curve proves that the SUs deliver the goods where the engine is used most. Thus is why Ford copied the SU with the Variable Venturi 7200 Motorcraft 2 barrel carb in 1978 to 1991. Because Police 351's carried those carbs for 10 long years on 164, 172 and 190 hp High Output Windsor engines. Skinner Union, the carbs Americans Envy 🥝✔️✊

Hi mate, good to see you working on Pinto motor 😊. What is the better carb to use on Pinto, Side Draft or Down Draft? Cheers

i had 1 of these spent big dollars = got 235 bhp @6,500 = got rid of everything = GOT A SUBARU TURBO = 280 bhp = easy - next step 365 bhp bigger turbo = better fuel ! = love me english sports cars = 50 years = moved on now !

1988 , HIF6 SUs .. knife edged the butterflies and removed half the pinion .. and mounted with allen dome heads.....gas flowed internal a bit , machined radius the pistons... changed jetting . spring .oil.and had some other air work done inside on fuel and air balancing .. Mounted to standard 3.5...low milage..40k with polished balanced chambers in heads.. , ..with tube exhaust...and a mild cam...., shit , i still had old rope seal on crank..lol...... pulled , after fettling , all the way to 210@ 5800rpm .. great thing was , if you drove like Miss Daisy.... you could get some great mpg..... Had plans to do a twin 2 inch SU conversion , from old J@@@g.. never got round to it... i always wonder how that would of worked out.

On any “vacuum” secondary or air door controlled carb it’s a good idea to make sure the secondaries are reaching WOT. The 500 is calibrated for a small American V8 like a 289 Ford. The 3.5 may not open the air door all the way.

Your balded head is bit of shiny to see trough hahaa 😄Just kidding Graham. But ya know, simplicity that works is the way to go for lets say moderate use. I think a Rover 3,5 fresh rebuild would be fun in an old Ford Cortina or other lightweight car anyhow. Just the sound and low down torque makes one already happy. I might go buy for cheap in living room for display a Ford flathead. Thank's man, best wishes for newyear and have a nice Christmas
