INTERNATIONAL 345V8 IGNITION DWELL ANGLE

Hi guys I am doing a tuning check up my ACCO 510A 345V8 and if anyone knows the dwell angle for that engine it would be very appreciated.
Thanks in advance .Abbuss

Timing is set at T.D.C., spark plug gap is .030" and dwell is 28-32 degrees.

Thanks very much Lang we will see how she goes now.Abbuss

Lang are you sure ignition timing is set at TDC?

That is from a 1973 American International 1110 workshop manual.

There is a bit of discussion on the International site saying if the 345 is pushed to 3 deg BTDC they are prone to overheat before any detonation is evident. Like all discussions there are people for and against.

Here is a bloke showing how to time a 345. He suggests maximum 5 deg BTDC.


This bloke says 8 deg BTDC but it is on a Scout which consistently runs higher revs than a truck.

When available I always set the points by dwell, just seems to be a better result.

These came out of my international workshop manual , these should be relevant specs for a 345 Just remember that when you time the engine with a timing light the pickup must be on cyl 8 , cheers , jim.

Why on #8 Rattail? I've not heard of that before and on the car V8's I've had I always did it on #1 with no issues.

Yep, Inter V8's are definitely timed on No.8

Yes the correct cylinder is number 8 not number 1 like every other V8 in the world , remember I have one too , I timed mine on number 8 the other day and it’s running perfect, Here is just one example below cobba
