I have Cometic making a head gasket for this one. The bearings are King brand bought in US. Funny I have been worried about over caming engines for years and now I'm concerned about under caming this one. I have a Kent 276 on a new blank. I had considered a light flywheel but now thinking more cam and a heavy flywheel to help smooth things out. Parts coming from all over, block should be back from resurface before the holiday. 

This engine was to be a 1430 74 mm bore offset 1300 stroke crank. I had a Magnuson super charger and planned to autocross it when the Super charged, short wheel based, F/SV, wing cars showed up. With 11 inch 4 pot disc, 7x13 wheels and 10x20 slicks just a little more grunt was needed. Went vintage racing instead. Steve (CTR)

Somewhere around 10 plus years ago my 1430 had a problem, blew the head gasket between 2 & 3, and burned a piston.  I call or emailed to order a replacement Mega 73.5 piston set resulting in hearing "it's on backorder".  So I called a different source for a set of Omega 73.5's for the stroked engine and ordered them.  The plan was to use whichever piston set arrived first.  I had two engine stands waiting and both orders arrived on the same day.  Mega's went to the machine shop to be topped and I built both engines.  As for the cam I used the CAM103 from our host. 
I have tried the Kent MD286, and the 286SP.  As for carbs or carb I'm running a HIF44 with a BBC (or BBW) needle.
If you pickup the October copy of  HOTCAR (October 1976)  Dave Vizard goes over the 1430 build stating they used the
CAEG643 cam.

I recently read an old Mini World article about twin HIF 44s. Not sure how this will work out. I had a front sub frame powder coated for this car. It turns out it is a sub with the motor mount bolt holes in the org. position. I will be having another with the forward location mounting holes and long dog bone done. I hope the 1/2 inch will be a big help. I have been sawing the MGB carb spacers into different thickness ones to see what will fit. If its a problem I still have DCOEs, HS 2s , HS 4s, HS 6s, single HIF 44 and a few other options.

Still would like to hear from someone who has used the Evolution 1 camshaft from MSC. Trying to avoid the common problem of over caming the engine. A good idle and reasonable power to 5500/6000 is my goal. Steve (CTR) 

Not sure how you will get those HIF's to work? Clearance to the bulkhead is going to be a major problem I would think with those big float chambers?

My 1360 is a very happy unit from 1500 to 5500. I built it to 9.5 CR with a SW 5 type cam. The 1400 will get more cam and 10 to 1 CR. A 3.2 CWP should be a good in between. Still looking at these MGB HIF 38s, wondering about angle. Steve (CTR)

My 1380 twin cam with sc drops and sc tranny sure makes a huge noise, and it really doesn't like town driving. It just wants to go, so it is a good thing that I live in the country. All smiles all the time. Cheers

I used to run a 1400 on the road as my daily driver, I'm afraid to say it sucked big time! Not the motor itself it was great fun, just that trying to run a big lumpy motor at town speeds just didn't work. It blew head gaskets frequently across 2 & 3 which I was expecting but also ran the piston rings out on 2 & 3 due to I think to overheating at the very thin block between the cylinders. But boy was it fun on the freeway. The noise from the 45DCOE plus the SC drop gears and SC transmission made it hard to be stealthy though............

PS The cam I ran was the special tuning sprint cam, which is one stage above the old 649 but the added cc's calmed it down a bit. But still too much cam for a street motor

I have a sneaky suspicion that the stroked motors prefer a bit more duration on the cam before getting all lumpy, but I can't find my reference right now.

That was done in the early 90's for clearance issues when they started using the HIF before the SPI came out, the stabilizer bar is also longer to match.

Thanks for the feed back, I will contact Cometic about a head gasket. While I at one time had a set of Triumph pistons and a stroked shaft I sold the pistons in favor of the 74 mm mini pistons with 9 cc dish. Miss spoke .009 and .012 should get me in the 10.1 to 10.3 range. I still have the off set ground stroked shaft. I feel the tufftrided  GT shaft will have a better life in this engine. 

While mocking up the intake system on cyl head clamped to work bench I noticed the MGB HIF 38s throttle shafts rotate the opposite direction from a mini. I will need to look for some linkage to make that work. I guess no one has tried the cam or carbs. If I find someone to post the pictures we will see what I come up with. 

Noticed a couple of things while knocking around the shop yesterday. Not sure when but the front sub frame motor mount holes are moved 1/2 inch forward of earlier frames. Have not measured but was also told that Hydro subs are taller than dry. My powder coater is back in biz after relocating. Going to do a batch of front subs on a come back home deal. Steve (CTR)

I ended up with a triumph-pistoned, stroked-crank well-used mini engine that came from Aaron Anderson that I believe was one that was built by some weight-obsessed Canadian fellow.

Didn't come with a head. I had to hog some head chambers out to something like 27cc to get compression down. It ran a Piper 285 cam I believe. I also had to run a Cometic head gasket because of how the block was bored. it had been thinned even more between the bores. Aaron said he made a lexan template to do gaskets consistently.

It really hauled the beans in an America using a single HIF6 carb with a custom tapered needle. It wasn't custom for this setup, but it was the thinnest one I had that gave it good AFR numbers at high end and under load which is all I really cared about.

Loved to suck up oil, too. 

I had to retire the block for good when water got in the bores and caused pitting that couldn't be cleaned up.

I have had a set of 74 mm power max pistons I had skirt coated with PC 7 or was it 9? These have been on the shelf for years waiting their turn. I have a old GT block that failed to clean up at .060. Decided to have it off set bored to 74 mm and build it up for a street car. Installed crank and using a polished down piston pin I checked piston to deck using one piston and rod in all bores followed by all pistons on one rod in one bore, one at a time of course. Found the block surface to have a .003 slope front to rear. If my figures are correct a surface cut of .009 one end and .013 the other should end with 10.1 to 1. I'm wondering if anyone has used the Evolution 01 cam from MSC? As for head a MG metro 940 casting with hard seats and mild porting around the guide bosses. I have a couple of MGB HIF 38 twin carb sets. Going to give them a try with a LCB. The spacing between bores makes me nervous but it must work. Any info about cam or carbs would be of interest.
