Timing Q and picture Q

Hey Ford Gurus...

I have two questions I hope you all can take a second to answer.

I want to bump the timing on my 1980 351M. I set my 5.0 Mustang by ear and it works well. Is there any reason I couldn't or shouldn't do this to my Bronco. I'm just thinking a small turn of the distributor until I get a ping on 87 octane, and then backing off a bit. Is this okay? It made a nice difference on my Mustang...

Also, take a look at this website http://www.cardomain.com/memberpage/366552
this guy just cut out his fenders and got 35" tires on it no problem. Is this stupid? Or is this guy very smart? As you can tell, I'm thinking this is the way to go on my 1980. Advice?

Thanks again all...

Brad

That's how I do it. I make sure the engine is crankin at 3000rpm first with the vac advance disconected. I've also heard using a 351C cam will liven the M motor up. The Cleveland motor I believe came with 4 more degrees of advance than the M motors did which makes a difference apparantly. Here's a good link I found awhile back which may have some more ideas for your M motor. http://www.projectbronco.com/Technic...e_build_up.htm

You can do that, but why not tune it to the highest vacuum reading you can get and then back off a little (with the dist vac line disconnected).

Try reading this;

It's how I tune my Mopars and it works like a charm for maximum performance and mileage.
