do any of ya know what a f1 weighs with a 351 and auto trans m11 front

 

No, but you should be able to find a local grain farmer who has a scale in one of they're barns in your neck of the woods, most of the farmers around here have them to weigh they're loads for the cows "custom" blend..,before it goes into the silo.They may get a kick out of seeing your old truck..ask around at local Southern states or grain/seed supply houses. Next try might be the nearest interstate truck stop, most have a scale.

 

well its still in a million pieces was going to install brake booster off of a fox body mustang there weight is 3350 wanted to make sure there would be enough oil to stop me with out a anchor

 

If you do a M-II right, it may not weigh less than stock. The 351 vs a flatty is probably 50 - 75 lb less, but your A/T weighs about 50 - 75 lbs more than a stock 3-sp. Not a lot of difference overall at any rate. The booster has nothing to do with brake performance, only braking effort.

 

Echo Echo Echo!

It will be within 50 pounds of the original truck.

Flatty in a 55 Ross? Shhhh! Just a slip I know, but I promise not to tell anyone!

 

So...what does an original 55 weigh?

 

found out about 3325 dont know what engine. a 88 mustang weighs 3350.

 

OK- that's not too bad.
