The "CAM003" cam has been produced by Mini Mania for well over 20 years and has been used extensively in our 1380cc engines becoming legendary in its own right. It is the ideal road cam for 1275cc or 1380cc, below 5500 rpm the CAM003 produces more power than the 286 profile. The average driver spends 90% of his use of the car below 5,500rpm. Our 'Second Generation' '003' grind is now called "CAM103". Not only does this produce over 115HP in our 1380cc motor but it is even more streetable, pulling strong from as low as 2,000 RPM up to 6,500 RPM with ease. All of this with stock ratio rockers and single 1 3/4" carb. One of the added features of the "CAM103" grind is the great performance in small bore applications such as 998 and 1098cc engines. Though not know for their high rev potential, 998's and 1098's with this second generation cam will have all the bottom end you will ever need transforming the engine into a hot street version.

My Vehicle: 1967 Morris Minor Van, with 1275 engine & ribcage gearbox.
I’m looking for improved mid-range torque, 2500-3500RPM. What do you recommend? Your high-performance 1275 & 1380 engines seem built for top end power, can you build a version built for mid-range torque? I prefer the 1275 and twin SUs, but want to hear your recommendations.
Answer:
Most of our engine builds are actually made with a camshaft profile (CAM103) that provides better low end torque. The idea is to give better acceleration at the lower RPM's where it's most useful for street cars. We don't have core charges on engine rebuilds because of the cost to ship them.
We run the engines in on a test stand so we don't have any detailed run-in instructions. Most engines run on 30W non-synthetic oil - some hotter builds will run 20-50 redline.

Question:
I have an Hif 44 carb on a 1275 engine. The carb has a red spring, .100 main jet and BDL needle. Is this suitable for use with a cam103 and 1.5 lifters?
Answer:
That would be a good needle to start with and it will probably work just fine. As with most SU carbs, you have to have a starting point and then you can try different needles either richer or leaner according to your need.

The secret of the 115HP, 1380cc motors! Mini Mania with aid of Dema Elgin designed a series of cams some years ago! These cams are US made and are of unequalled consistency and quality.One of the designs was for a mid range camshaft that truly tries to please everyone. This cam has a 264 degree intake and a 268 degree exhaust duration and intake valve lift of .327" with an exhaust lift of .358". Elgin cams are not as cheap as some competitors, but we believe that the quality is worth it! Fits any 1275cc! . At TDC intake opens at 25 Deg . , and exhaust closes at 27 Deg . At BDC intake closes at 59 Deg , and exhaust opens at 61 Deg. Valve clearance intake is .014" and exhaust is .016 ".
NOTE: Pin drive cams will require sending in a suitable core for regrinding as these cams are becoming more and more scarce.

Finally getting around to rebuilding my 1275 motor and installing this cam which I bought from you years ago (not installed until now). Currently have stock rockers. Would this cam/motor benefit much from going to a 1.5 rocker set up? I'll install with Maniflow LCB header/exhaust and stock SU carbs
Answer:
There are several factors involved when changing rocker ratios. I recommend this ARTICLE to help you make an informed decision.

Considerable information has been recorded about numerous aspects of the four stroke internal combustion engine. Nevertheless, only a small percentage of people really understand how it works and even fewer still know how to modify an engine to suit their needs. I will try to simplify this complex subject by discussing some basic principles that may be overlooked or misunderstood by the average person.
