HO Upgrade or HO swap? October 07, 2010, 12:30:47 PM I''m sure this has been talked about before. I did a quick search, but didn't find anything specific.I'd like you opinion...I have an 88 Cougar LS - SO 5.0. I'd like to do the HO upgrade. I have mapped out the costs of doing the upgrade to the existing motor. It looks like about $500-600. Pretty cheap for 60-70 hp bump.But, for that price, maybe I should just look for a factory HO?The costs include a used cam, rebuilt heads, injectors, computer, new fuel pump and all needed gaskets and all the little stuff to do the upgrade.Thanks!

HO Upgrade or HO swap? Reply #2 – October 07, 2010, 12:49:34 PM JMHO , I did the conversion minus the E7 heads for less than $200 by shopping around ,I got my H-pipe upper intake and fuel pump all for $40 on craigslist, the cam and computer I bought here for $80 and my injectors I got for $10 on ebay . Then the timing chain misc gaskets ,oil, and antifreeze was about $60 Of course I did a compression check and oil pressure test on my engine before doing any work to make sure I had a healthy starting point . Personally for me the E6 to E7 swap didnt seem worth the labor involved taking into consideration the abundance of heads that are better than E7s, now I'm not saying E7s are not better than E6s because they are , Just in my opinion not that much better that the labor is worth the increase. According to Ford ratings the E6 engine was 200hp the E7 was 225hp... to me If I am doing a head swap I want more than 25 hp If further mods are going to be done it may be worth swapping heads I personally am only going from SO to HO and nothing else . Oh yeah ,I also got my factory shorty headers for free too :D Quote Selected
HO Upgrade or HO swap? Reply #3 – October 07, 2010, 01:11:42 PM Why not just switch the whole motor? I dont know about where you live but you can find a HO motor fairly cheap around here OR go to the local pick n pull and grab an explorer motor and swap the cam (here its $215 for a complete motor). Some junkyards ive seen will sell a nice explorer motor for around $500 and they pull the motor. Just drop it in and go and with an explorer motor you get better heads and intake then the E7 stuff.

HO Upgrade or HO swap? Reply #4 – October 07, 2010, 01:23:00 PM you're better off swapping the motor.. better pistons for better valve clearance(valve reliefs) when running a larger cam.. it also opens up a whole new world for cam selection.. the pistons are also forged.the explorer motor is a VERY good option. it's 1 of ford's best factory late-model production 5.0's. an explorer motor with a mustang MAF harness, aftermarket cam and distributor(whether stock or aftermarket) is the way to go in my opinion Quote Selected

Also dont the explorers have bigger MAF and TB? Quote Selected

HO Upgrade or HO swap? Reply #9 – October 08, 2010, 02:08:20 AM An explorer engine is in my future..rather, the sport's future.I had several HO parts laying around that I was going to convert an SO that i'd picked up, but a friend had bought a stang gt convertible just for the top, so I got the driveline and some other bits, and threw those into my 'bird. Now that i've had a little fun with that, it's time to go full tilt boogie with it. A thorough rust removal, clean, blasting, repainting, and then a gt40 5.0 in the spring.I wouldn't mess with tearing apart an SO block just to go from 155 to 225 horsepower....drop in an HO and be done, or do like I plan to, and get the explorer engine, swap oil pan, and throw a dizzy on it, and enjoy.

My thoughts exactly , swapping a cam is only a few hour job, cam and heads ,and you are close to a rebuild . BUT I would never just install a junkyard motor without being able to hear it run. first .

BUT I would never just install a junkyard motor without being able to hear it run. first .or at least doing a series of checks.. cooling system pressure check, compression test, pop the pan off, check the rod/main bearings and crankbut in all honesty, i would never buy a junkyard motor without the intention of rebuilding it once the bearings are disturbed Quote Selected
HO Upgrade or HO swap? Reply #13 – October 08, 2010, 12:52:46 PM In all honesty the only stock heads worth swapping on to a HO are GT40 or GT40P irons. Any other stock heads are a waste of time. If you want to reuse your stock SO short block, run a HO cam, and have some good heads look at the Trick Flow TW head. They should clear everything no problem;) Quote Selected
