I've been following this build with great interest. I had a 1971 Pinto Hatchback which ran a best of 16:45--80 mph flat with only the addition of headers and richer jets in the carb. At that time the National record was 16:25---83 MPH. I never had the funds to campaign the car. It needed a locking rear end and bigger rear tires. Also the transmission had the very low 1st gear causing a power drop after the 1-2 shift. A transmission change was needed also so it had a more favorable gear. Fun little car though.
A proper screamer that is. I wish he would make an extensive and complete video on porting the pinto cylinder head, or at least show us in detail how a properly ported cylinder head is supposed to look like. I'm gathering funds to properly port, and set up a cylincer head for my MK2rs with the efi, with 44.5mm and 38mm valves and a High torque cam from Burton. It would be great with some valuable input. I've got the David Visard book, and the "how to powertune the pinto" book, but a visual representation would go a long way.
Hi Graham, love watching your vids. Have you ever done a side by side comparison on simpson vs tony law headers on a dyno run? If not, I would love to see that.. especially considering how expensive simpson exhaust are compared to tony law. Keep up the good work.
Great build 👌 I suspect my capri 2.0 pinto needs some jetting work as im getting pinking on the top end as you go into the second choke, (standard weber carb) at higher speeds. Do you think bigger main jets would be the way to go?
not done a 1.6 for many years, essentually they tune same as 2.0 EXCEPT you really do need to be careful with cam and carb selection or you end up with a really revy engine which has no torque
As an Aussie I would love to have an engine built and setup by Graham. Also it would be interesting to see a pinto head built with the David Visard Polyquad idea of having the exhaust set further up in the head so the intake mixture goes over the exhaust on cross over. ruclips.net/video/-vY5Z3nCJLQ/видео.htmlsi=YQsxzJDrVG3S071D
That's around the same No's as the best GRP1 on 40mm DCNF's all be it on better fuel. Ign. timing was 36 deg. Not 100% sure if Pipers GRP1 cam was the same as an original Ford item 🤐 😮 torque and RPM were the same No's also. So long ago it's irrelevant now🙂 Referring to your first pull.
What was the advance curve of the Bestek distributor if it was advanced from 28 deg to 34 deg without having too much ignition advance lower down in the rev range or was it altered to suit
i never expected it to work properly with only 28 degrees advance, you have to start somewhere and you want to start at a safe number which is why i started at 28
You’re the “Yoda of the pinto”!👌🏻

Another very instructive video - thank you!
Brilliant Graham. Love to see the end results
Quality content💯
Would have been interesting to have se what the curve would have looked like with a pair of 45's.
Not a great deal different I have run similar spec but on 2.1 on 45’s this has a fatter/flatter bump at the top
Great help on my decision on Pinto build for a fast street motor
Great stuff, beautifully explained💯👌🏾
That will be a sweet engine for the road. Driveability would be nice low down but yet loads power up to 5000rpm. Perfect for the road
Great video, that engine should be very good in the 1st half of the rev range and exciting in the 2nd half.....win as you say 👍🏻😎
learning all the time my friend
Love what you do, keep doing it. Cheers
Enjoyed that 🚗💨👍
I'd like to know what the owner thought of the rebuilt engine, as in the difference in how it drives
Love the video
Nice job Graham, I didn’t expect the RL31 to beat an HT1…
To be fair I don’t think the engine before rebuild was making full use of the HT1 and we are definitely towards the top end of what the RL31 will do.
thx

No I haven’t unfortunately I don’t own either a simpson or Tony law, and they are just to expensive to buy just for testing purposes
Yeah fair enough. I have a set of tony laws on a n/a yb build. One day I might get a Simpson set-up to compare. Thanks for the reply
Really nice work. What is this cam again?
Kent RL31
👍👍👍👍👍
I'm surprised you didn't go down from the 50 DCO/SP to 48 DCOE to get the airspeed up.
simple answer, customer didnt want to change the carbs
Quality content.
How much quench is there?
Not a huge amount about 50 thousandth’s
Great build 👌

Do you think bigger main jets would be the way to go?
you dont say if the engine is standard, but for sure, even after just an airfilter and exhaust swap the standard carb needs bigger mains
@@PenguinMotors thanks for your reply.
It has a 421 exhaust and is bored 1mm over.
Would you have any recommendations on jet size?
Hi Graham I have a 1.6 pinto do you ever tune a 1.6 it's what I have in my pop and want to keep it.

Ridiculous ;)
Try bigger chokes
The idea was to make it more drivable not less! Those chokes are big enough for well over 200 bhp

@@PenguinMotors do you know the difference in horse power between the straight intake and the offset intakes to clear the distributor?
