Yes, i thought about putting both pulley on a bench and transfer the mark from the 948 on the 1275.

However, i was wondering what the difference is in degree.
If i was the use the 1275 marking on a 948, is it advanced or retarded and by how much?

I finally received the Vizard bible... in the 850/948 tuning part, he seems to think the triple camshaft white bearing is required from 265-270 duration, not an issue with 250 which is good to know.... but as I had to refurb the carbs, i m not going to fit a camshaft, follower and possibly oil pump ...

As I said before, looking at the old cracked head, I noticed the double valve springs which are supposed to be on 9cg, 10cc and 10cg engine but not on the 9c... so l looked at the a little further... and with the head casting is a 948cc 9c, it has been the valve trains was converted to 10cc spec, in...

As I said earlier... this engine is a mystery... It appears the the twin hs2 carb are fitted with 2 different types of needles.... so I will get 2 new one so that they balance better. Now on a ported head with cooper size valves on a 998cc flatop, what would you put. i read a su manual and it clear ...

Humm, it seems the old head was fitted with double springs...
This engine keeps being a mystery.

Ok so that's what I am trying to understand. The problem come from the accumulation of increased lift and the load from the double spring. So does this mean that it is ok to either use -std cam with double spring -997 cam with single spring. now why do double spring get fitted? is it to avoid valve ...

I did further researches. It seems the 1098cc (AEA630) and 997cc (88g229) could go in 9C engine however if going further, 9CG was required.

I found various data a cross referenced them.

reading the abingdon tuning manual, it seems they used to fit the 88G229 on 9C engine (single white metal bearing) and 9CG (Triple white metal bearing. Were there issue reported with that and corrected or was it an accepted issue that people took? M'Odel Sprite H/ANS, H/AN6 & MIDGET G/ANl Engine...

For what it is worth I would not fit a 997cc Cooper or performance cam without having the 948cc Block fitted with a full set of white metal bearings. That's the sort of thing I was after. I want to put the car together and do things once while it's opened but I don't want to add loads on extra work...

Were the 997 single white metal or triple?
If the earlier then, it works for me as I don t want to strip everything and machine the block...
Hence my earlier question on specs.

I miss explained myself; I thought the early one had 3 bearings with 1 shell in the block while the 2 other seat on the block while the later ones have 3 shells

Good. What’s the spec? How does it differ from the 948 (8G712?)? 997 is 88G229 and I read that the cam profil came from mga and b. Is this true? Is it a single bearing or triplebearing I believe std 998 had the 8G712 cam but the 998 cooper had the AEA630 & 12G165 also shared with the 1098. What ...

A couple of months ago, my engine went pop... hgf :( After inspection, the head is cracked so junkyarded or door stop :( but good thing is the block is already 998cc with flat top piston... so I m getting a small bore ported head with big valve and higher compression. Electronic ignition will go in ...

Well, I'm gonna have to look at that soon as I noticed that after 5 miles, the car squeals a little when pushing the clutch pedal...

I was thinking about the clutch plate last night... so for competition use (High torque) they use 9 blue springs. For fast road, 6 yellow and 3 blue.

Where can you get the blue from or can we find about what their spec is?
Also, is there a merit to fit 9 yellow?

The number of your engine indicates that your engine has already been factory reconditioned so dimensions i.e. bore diameter and crankshaft bearing diameters may not be standard. It would be good to know the dimensions as of now. Thanks Phil, you re a fountain of knowledge. If it was reconditioned,...

Mine is a 8G9... so nothing special
