Does anyone know if there is a Ford factory manual for building these motors. I know these motors that went into the Mustang Cobras were built by two man teams.

porting and polishing

mogman — Tue, 14 Jul 2009 20:56:27 GMT

Ive heard many people say, mostly car enthusiast that porting and polishing works like a charm and its the best thing to do for maximum perfermance. i once read in a superchevy mag. that the porting part works but not the polishing part so i asked the machinist where i worked and he agreed. so i want more opinions or the truth to this myth.

Harley Crank Balancing Question

bbaker — Tue, 18 Mar 2008 14:41:51 GMT

I have a question from a reader asking about how to balance a harley-davidson crank. Hopefully someone out there can help him out. Thanks.

Here's his question:

Is the bobweight card the same as V8? Do you weight match the small end of the rod and the big end, and pistons? Then, do you use 52% recip. and 100% rot.? Then remove or add weight to flywheels? What about the weight of the crank pin bearing?

Checking Machine Shop Work

jesuscowboy — Wed, 01 Jul 2009 22:17:34 GMT

I had local machine shop overhaul 351W block; just curious can I check his work to make sure everything is good. I just bought a bore gauge to check mains and rods. Also I can check cylinders for out of round and make sure tolerances are good there but what about the line bore of camshaft. He installed cam bearings so can I still use a straight edge with feeler gauges even though the cam bearings are in. Also what do you guys recommend for engine lube (brand). I had someone tell me to use ATF on cylinder walls. I will use mellings cam and there assembly lube. I have heard some say use just engine oil some say only use moly paste, others say just use over the counter engine lube.

3.0L Ford Engine F6DEDE Block number 1995 to 1998

philip caron — Sat, 14 Nov 2009 17:35:12 GMT

Ford Taurus year 2000 flex fuel engine.

Can the subject 3.0L F6DEDE complete engine totally replace a Ford Taurus 2000 flex fuel engine?

Is there a problem with the computer set ups for the flex fuel that would cause a problem running the 1995 / 1998 engine for timing etc.

What needs to be changed to adapt the 1995/98 engine to operate in the 2000 flex fuel Taurus?

compression and leakdwon test?

jetblast — Fri, 13 Nov 2009 22:10:11 GMT

anyone here done these test often? i was curious if good test results can still be misleading. my motor has 83k hard miles. and blows the dip stick out but, only about an inch. i replace the valley cover hose with a home made catch can that is working pretty good so far. the motor is pulling 15hg steady vacuum. oh, i have no oil consumption problems either and the plugs look great.

i have been spraying the motor with 100w shots for a while, this season alone i have over 28 1/4 mi passes and i spray it all out, no progression.

i passed the compression test with unexpected results...
#6,8 cylinders developed 195psi hot, the rest were 200psi hot. while viewing the gauge for pump up, i cranked the engine 4 pumps on all cylinders.

the leakdown test was done with the engine cold. {overnight}.
the results were between 90% 92% for all. i would appreciate any seasoned experienced opinions.

If a steel crankshaft has been polished to a "10-10", what exactly does that mean?

Choosing a 4 port carb for trackdays

petterhval — Fri, 23 Oct 2009 20:33:35 GMT

Hi!

I have a seven style kitcar fitted with a Rover 4.8L V8 (based upon the old 3.5L Buick design), which is tuned with ported heads and a hot camshaft, supposedly putting out about 350bhp(at the flywheel).Currently it is fitted with a Edelbrock 600cfm carb, and it does not work very well when cornering on the track(it is misfireing). I have heard that other makes(of carbs) make 4 port carbs better suited for my use. What would be your recomendation

Regards

2000 Chevy Cavalier needs new engine

Jane Anderson — Tue, 13 Oct 2009 12:44:02 GMT

My fiance's 2000 Chevy Cavalier needs a new engine. He seems determined to fix and keep the car. It has about 150,000k mi. and he's already put new water pump , battery and had existing head gasket repaired. It was overheating and now he's found an engine on the internet, I think the company is called Everready or something. The engine and installation cost about 2,900 and they guarentee the engine for 3 yrs. I just want to make sure he isn't getting ripped off. He said they have been in business for 30 yrs and we could check with Auto Zone .

Pete still owes 1,700.00 on the car loan and so since he has to pay that off he feels fixing the car is best

Please help with your expertiseas he's planning on getting this by the weekend.

Many thanks,

Jane

Competition Cylinder Heads

bbaker — Fri, 17 Aug 2007 18:17:34 GMT

I'd like to get a discusion going about selecting cylinder heads for drag racing (i.e., bracket, street/strip). How do you choose the right heads these days with all the choices in the aftermarket? Do you really need to port aftermarket heads or can you match them to the right combinations without porting? Should you choose heads based only on the flow numbers?

Intake Manifold Gasket

tataylor — Sat, 15 Aug 2009 16:50:24 GMT

Hi - I'm installing a crate motor in my son's 1995 firebird with a 3.4L V6. The lower intake manifold gaskets have different sized restrictors on one of the coolant ports. Can anyone give me some guidance as to which gasket is for the right or left side? I have a picture from of the old engine and it appears the larger hole is on the left, but the gasket has a R stamped on it. The other gasket has O stamped on it.

Any help would be appreciated.

I need your help - dealership claiming I damaged bearings in engine

Shelly — Fri, 07 Aug 2009 20:54:40 GMT

I took my car, Subru - WRX/STI into the shop for them to check the blow off valve. When I picked it up and went to leave I new something was wrong. When I brought it back to the dealership they opened it up and stated that the 3rd bearing was bad due to lack of lubrication. I've always kept the oil clean and full. They are stating that the only way this could have happened is that I took a sharp turn at a high rate of speed and the oil pulled to the side, causing metal on metal. I just drove from Idaho to N. Carolina without any incidents. This noise did not occur until I went to pick up the car. I realize this is a high powered car, but I haven't taken turns like they have claimed. I contacted Subru and they have stated that they found that there isn't any defective parts, therefore the warranty doesn't stand. I new engin was put in 8 months ago. I really could use some advise - they are stating this will cost $4,500 to fix. Please - help me.

Comp Cams 6500 / damper fitment

SoCalJim — Thu, 30 Jul 2009 19:52:30 GMT

I have a SBC (Dart SHP) engine that I’m putting a Comp Cams 6500 camshaft belt drive on. I am having problems getting my Pro Products 90002 damper to fit. The damper outer ring hits the thick washer and bolts on the camshaft pulley.

I had the washer turned down to clear the damper, but now the damper ring hits the six camshaft pulley bolts. If I mill the bolts down to fit, there will only be about .210” of bolt to get a nut onto. I called Pro Products and they say all their dampers have the same outer ring offset. I can’t use shims to move the damper further out because there’s only 1.050” of snout mating with the damper now. I called Comp Cams and they said “There is nothing abnormal about our belt drive that will require a special damper, any everything should work.” I just need a damper (preferably 8”) whose outer ring is about .200” further forward of the block face. Any ideas?
