7MGFORCE Posted January 20, 2009 Share Posted January 20, 2009 hi i been looking for this info on the net and on the site. how can i tell that a 302 is HO? (physical) and do all mustang "fox body" came with HO v8? Quote Link to comment Share on other sites More sharing options...
Challenger Posted January 20, 2009 Share Posted January 20, 2009 Not all were H.O. I know the GT has the HO, and I think the LX doesnt, though its still a 5.0. Quote Link to comment Share on other sites More sharing options...

Challenger Posted January 20, 2009 Share Posted January 20, 2009 All the LX's Ive seen are the 5.0. But Im pretty sure they're not the H.O. Check wikipedia. Quote Link to comment Share on other sites More sharing options...
7MGFORCE Posted January 21, 2009 Author Share Posted January 21, 2009 All the LX's Ive seen are the 5.0. But Im pretty sure they're not the H.O. Check wikipedia. i check that and reread it. unless it miss something but wiki doesnt even mention HO. it just said that 87-93 was iether 2.4l or 4.9l Quote Link to comment Share on other sites More sharing options...
74_5.0L_Z Posted January 21, 2009 Share Posted January 21, 2009 If the V8 was in a Mustang (87-93) LX or otherwise, then it is an H.O. The GT was a body/dress package (hatch back, stripes, better interior). Many people seek out the LX V8 cars because they were lighter than the GT's. The 5.0L engine from the Mustang LX is the same as the 5.0L engine from the Mustang GT. Non-HO 5.0L engines were installed in Thunderbirds, trucks, and other non-mustang fords. The non-HO 5.0L engines had different heads and intake manifolds (as well as smaller 16 lb/hr injectors) The engine that is in my car was from a 1989 Mustang Highway Patrol vehicle. The highway patrol vehicles were V8 LX cars. Quote Link to comment Share on other sites More sharing options...

ArizonaZ Posted January 21, 2009 Share Posted January 21, 2009 Yeah I have a 93 Mustang LX 5.0 and it has the HO Quote Link to comment Share on other sites More sharing options...
V8INtheZ Posted January 24, 2009 Share Posted January 24, 2009 Yeah I have a 93 Mustang LX 5.0 and it has the HO 93' has hypereutectic pistons, 87-92 are forged Quote Link to comment Share on other sites More sharing options...
ckelly78z Posted January 24, 2009 Share Posted January 24, 2009 Generally, are the hypereutectic pistons better, and stronger than the forged units ?? The forged pistons will handle quite a bit of horsepower, how do the hyper pistons do ?? Quote Link to comment Share on other sites More sharing options...
V8INtheZ Posted January 25, 2009 Share Posted January 25, 2009 The hypers are lighter, and usually have a teflon alloy skirt to help rubbing the cylinder wall. They can rev faster and higher cause of the weight savings, and they dont expand as much when they warm up. They are just fine for NA engines. Forged pistons are stroger, but a bit heavier and hold up better to NOS and forced induction. So neither is really better than the other unless you plan on pushing the pinging limits then go with forged cause they can take more abuse.

74_5.0L_Z Posted January 25, 2009 Share Posted January 25, 2009 The hypereutectic pistons and forged pistons installed by Ford were approximately the same weight (about 600 gram). As stated earlier the forged are stronger. The good thing about the hypereutectic pistons is that they expand less with temperature and can be run with less wall clearance. Both are fine for an engine that won't use nitrous or supercharging. Over the Christmas holiday I removed the 5.0L from my car (after nearly 9 years of use). During those nine years the car has transitioned from being a daily driver with occasional trips to the drag strip to being a dedicated autocross car. I have always driven it in anger. During that nine years I never touched the stock bottom end, but I have added cam, heads, intake, injectors.... I have finally put together a new stroker short block with a new 5.0L block (4.000 bore), scat stroker crank and rods (3.25" stroke), Mahle Forged pistons (10.3:1 compression), rings and pins. The new Mahle Forged pistons weigh 393 grams. The whole rotating assembly was balanced with a Romac damper and Fidanza aluminum flywheel. I am using the same cam and heads that I had on the old engine, but have switched from a cobra intake with 24# injectors to an Edelbrock Performer RPM with 30# injectors. The new engine is in the car. I started it yesterday for the first time. I'm going to the dyno on thursday. I can't wait. Quote Link to comment Share on other sites More sharing options...
V8INtheZ Posted January 29, 2009 Share Posted January 29, 2009 Awesome! Im very excited for you...in a man-ly hetero kinda way Quote Link to comment Share on other sites More sharing options...
Netrix Posted January 29, 2009 Share Posted January 29, 2009 Lincoln Mark VII's came with 5.0 HO's also. It's a little easier to find those for donor cars, since they don't have a large demand like mustangs bodies with 5.0's. They only come with AOD 4 speed. 5 speeds are easy enough to come by if you want. Make sure you get a newer 5.0, as the older ones were 5.0 HO's, but came with speed density instead of MAF later on(1988 and up?). Speed Density doesn't account for upgrades such as cam, injectors, heads, etc. Just do a little research before you find what you need. As for identification, there will be a plaque or emblem on the top of the engine that says "5.0 HO". Can't miss it, regular 5.0 v8 will not have this emblem.

V8INtheZ Posted January 30, 2009 Share Posted January 30, 2009 The engine in my Z came from a Mark VII. Great source for HO engines, but they need to be an LSC Mark VII, not all had the HO engines. Still very easy to find in the yards and usually with low miles in the 50k-75k range. Quote Link to comment Share on other sites More sharing options...
Capt_Zorro Posted March 2, 2009 Share Posted March 2, 2009 Yeah, and usually the Lincoln HO's haven't had the crap ran out of them. Quote Link to comment Share on other sites More sharing options...
Guest josh90gtstang Posted April 18, 2009 Share Posted April 18, 2009 all the ones in the mustang are HO the LX was just the bottom end you could get the 2.3 or the 5.0 the GT was only 5.0 and had a body kit thats it and interior Explorers werent HO but the intake is WAY better than the ford HO upper/lower Cobra intake are a little better than explorer though, but the newer 5.0 explorer intake is a cheap way to go EFI and have good CFM airflow The ford trucks werent HO either, but i do believe most all crown vic motors were HO Quote Link to comment Share on other sites More sharing options...

How was the romac damper in regards to being out of balance or how well did it dampen... did your machinist make any comments on it? Quote Link to comment Share on other sites More sharing options...
