200 needs a rebuild...

[Ba Mustang]

Almost everything will be replaced. My 200 bore and rebuilt cost 2500.


EDIT: this is what was replaced and redone. I have the paperwork from the place that did it.

Oil Cap
Carb gaskets
Ring Set
Gasket Set
Main Bearing
Timing Gears
Oil Pump
Pistons
Cam Bearings
Freeze Plugs
Camshaft
Lifters
Speedo Cable
Clutch Arm Kit

The engine was bored .040, the head was reworked, and the crankshaft was grinded.

Yea, I thought so. So did you find any noticeable performance gains by the process, or is just something cool to do? If so, about how much?

 

[Ba Mustang]

the PO did all that. Then engine blew up on them. I added the 2v. My friend has a 68 with a 302 from a Maverick that hits around 150 HP. My 6 isn't much slower that it is. I currently haven't been able to fully test the ability of the 6 with the new carb since I don't have the throttle hooked up correctly. I have to order a piece for it. I was told the bore only added like 5 HP though.

 

[KHC67Coupe]

Hmm...only 5. Not very much...can you guess at how much torque was added?

 

[Ba Mustang]

I really have no idea. I am supposed to get it dynoed next month though.

 

[KHC67Coupe]

Well I definitely look forward to the stats from that. Luckily, I'm in no hurry engine-wise.

I really want to see what is runs. I was planning on a CAI to add more HP, but I can't fit an air filter on now. I have less than 2" of clearance between hood and valves of carb. If you use the adapter for the 2v carb go with the Clifford one, it will give more space than the one I am using.

 

[KHC67Coupe]

I don't care how expensive it is or if I'm going to need a new hood...but I WILL have a modular air-intake system before I am finished, maybe using the air filters down where my fog-lights would be...just take them out or something...i dunno. As for the Carb, when I get a 2V, i think I'm going to get the one that was recently dynoed on CI, the 240 CFM one, and then get an air filter that is compatible with the modular air intake. So I probably wont be able to use a spacer, lol. Ah well.

The 410 dollar carb. Maybe the carb will work good. I am using the H/W the is posted up in the stickys.

 

[KHC67Coupe]

Indeed, the $410 carb. And, eventually, the Aluminum cylinder head. Fun.

I can pretty much guarantee I won't get out of this what I'm going to put in, starting with hopefully a black interior rather than the red one. 8)

boring won't give you much, a .040 overbore gives you a whopping 204 cubic inches. thats not going to give you any gains in HP or torque, that money can be spent in much better ways.

 

[KHC67Coupe]

I always thought overboring would enhance performance. Hmm. So..what is it for? more space for air or gas?

 

[Ba Mustang]

You usually bore an engine when you have it rebuilt. It cleans the cylinder walls or something along the lines of that.

 

[Bort62]

Boring, in this case, is done to give a true surface on the cylinder walls.

Older engines, IE flatheads, used to be bored out to increase displacement - but that is a different situation.

You should bore the minimum required to clean up the surface. It is not a performance modification.

 

[KHC67Coupe]

Yea that makes sense. Thats what polishing is for the heads, isnt it?

 

[Bort62]

"Polishing" or more aptly called "porting" the heads is a process which smooths transitions and decreases flow resistance.

Yea, I read over that article earlier. Interesting...tis a shame I don't really know what its talking about. But that's why I've got the Forum, and my dad..he knows alot of this stuff, just not the I6 versions of it. lol.
