Refugee,
I have a US spec 72T motor that I'm currently trying to locate parts for. My P&C's were in a car accident which ruined them, and my case is way out of spec and I need either lots of machine work or a new case.

About the Zenith carbs and MM. I would do a search here on MM before you put too much stock in their advice BUT I've heard that with a little ingenuity you can machine your venturies to a larger size or put in weber venturies. That's the limiting factor it seems for zeniths, the small 27mm venturies. I'm not a carb person but I would think from looking at port sizes and gas speeds you would want at least 32mm venturies, others would know more than I.

There are people on this board who have machined their 3R case (check the bottom side of your case for this part #) for 2.7 P&C's but I was leary about this myself as these cases aren't very strong. If you have a 5R case or a 7R case, you can machine your case to accept the larger P&C's. Even if you have a weaker case 2.7 7R cases are a dime a dozen.

Since I'm a student and on a budget I decided to upgrade my T to highcompression E specs. I'm planning on using 2.2E pistons and cylinders with an E MFI setup, ported heads and throttle bodies (34mm from 29mm) and E cams. I think it should make around 180 when tuned correctly and cost me a little bit over 4K for parts and machining.

I'm helping a friend out who's doing something similar to my engine. His will be a 2.4 engine with solex cams and E mfi induction. So far we've learned:
1. plastigauge ALL your rod bearings.
2. clean ALL the thru bolt holes and perimeter bolt holes or you'll end up with crud on your mating surface.
3. Install exhaust studs BEFORE you assemble your engine (don't ask)

Hopes this helps.
