Looking good!

Few probs at the mo.

The BMW larger valves in the head, have a slightly shorter collet than standard. So I need bucket shims that are thicker than what's factory available.

Compression test come out at 9.9:1 so that's good. Wet test assembly proved enough valve clearance follow bigger valve pocket machining in the pistons.

Engines back in, but a few carb issues (taken home by Mr RAC today) so need a dyno run ASAP.

best thing out of italy imo.

would love to have been in the design office when they first drew the outline

Dyno run and carb setup, resulted in sharp drop in HP after 5300, so need bigger jets and probably a 123 dizzy.
Rebooked for 2nd run early August.

But even with these limitations it made 122bhp.
Not bad for a 1300 that's over 45 years old.

[jamieandthemagictorch]

Well she went back with bigger jets, they were a bit too big, so carbs off whilst we were there to make them a little smaller. Fitted the Bluetooth 123 electronic dizzy and played around with the advance curve.

Got 125bhp from the lil 1300, but the dizzy has made the starting, idle, and driveability on big carbs soooo much better.

[jamieandthemagictorch]

Another rolling road session, to sort a non-tick over issue and re balence the carbs. Still sitting at 125bhp

The car is gorgeous. My computers wallpaper is a near copy of your car....but it has what I think is called the step nose.

the Nardi wheel looks fantastic....the wheels are a great touch too.....

awesome....

Best looking Alfa ever. Although, all Alfas are special... Coincidentally, I got the same amount of power from Fiat 1.3L SOHC (8 valve) engine in my daily Yugo. Twin Dellorto 40's on intake, hi-comp race specs engine, basically... Driveability is faaar more important than the BHP number itself. So - keep on rolling and enjoy!
