and it starts... we put my friend's maverick under the knife yesterday. we started pulling stuff off so we can pull the motor. compression tests on all cylinders produced widely varied results. time for a motor rebuild. question... what type of cam should we go back with? we want to give the 250 a little more pep without getting too radical. he wants a daily driver (its his only car). but he also wants to keep up with atlanta traffic (avg. +20 over speed limit). we want to produce more torque on bottom end. we thought about the truck cam for the 250 but i havent had a great deal of time to research the differences. has anyone here upgraded their cam shaft on their 250? what were the results? if nothing else, we want the motor to be stronger and last longer than the original stock 250. he's the second owner. his grandparents cooked the motor once or twice. they ran it out of coolant. when he got it, it already had the compression problems and some foam/oil in the coolant. on the topic of a header, i think we might go with the stock exhaust manifold for now until he saves up some more bucks. that is a great idea though! i'll definately suggest it to him for future upgrades. we don't know what parts we will have to purchase for the rebuild until we get the motor out today or tomorrow and mic the parts. we both feel a little better getting a new master rebuild kit from P.A.W. (yes they have 250 stuff!!!). thats some big bucks though. $650 for the kit with an extra $140 for custom balancing = $900. its a nice kit though. it comes with cam crank rods pistons rings bearings gaskets lifters and timing chain/parts. they let you choose what cam you want when you place the order. thats our big hang up for now.
what cam should we co with?
ideas and comments welcome from all. thanks in advance for all replies.

Check out Mike's new FSP cams:

The 250 never went into a truck (other than the Ranchero) so all the stock cams are a going to be the same or very close.

Along with the cam, some time spent blending and smoothing the valve pockets along with a 3 angle valve job are time and money well spent. Also pay attention to your compression ratio. New composite headgaskets can be .030" thicker which will drop the CR. Milling the head will restore that. If you mill, find some hardened washers to put under the headbolts to keep them from bottoming.

If his Mav doesn't have the later Duraspark II ignition, now would be a good time to upgrade as well.
 
if he still wants good bottomend then get a small cam like 204 duration @.050 idle - 3000 rpm and if he is going 80 miles an hour he would be making power right were he needs it
 
What should the compressions be for a stock 250, anyone know?
 
The engine is in 69 mustang coupe. We were able to start the engine yesterday but i coulnd see the compressions, What should they be?
 
my book only go`s back to 1972 but it should be 8:0.1 good luck :D
 
Well, if tatao is looking for some quantitative assessment of his motor... Under 120 pounds per cylinder is showing appreciable wear. Less than 70 pounds in any pot is making very little power indeed; it would be considered "dead" in many minds.

A good stock engine - expect at least 150 pounds each, preferably more like 180.

Adam.
