Hitman47 Posted March 13, 2005 Share Posted March 13, 2005 I want to pass on some knowledge to you ford guys that I have been learning, I mainly want to right this Thread so when you guys have your motors and are waiting on my kit to be completed or when you finish the mounts yourselves you can do simple and very worthwhile things i have learned about. It will be an ongoing Thread whereever or whenever I learn a trick or swap or anything that the average guy can do to increase the power and/or strength of his 289/302/351w/351c. I will also provide Links as much as possible. Also I have many connections to some of the parts I mention and will give you guys great prices so if anyone needs perf 5.0 parts let me know and i`ll see what i can do. So here we go.

Hitman47 Posted March 17, 2005 Author Share Posted March 17, 2005 rudypoochris asked a question that Sparked me up for this post. 1st thing I will explain is the trip to the junkyard swaps these are great because Alot of 5.0 mustangs have seen the end of their days at the JY. Parts at these places are usually reasonable. So now I will explain how to make a 315 hp realiable engine out of a JY. This is what I did to build a 5.0 to 315 hp RWHP for under 800$. I will list the steps then explain them. These are all relatively easy steps, I did this without even finding those gt-40 heads. 1-Find a 5.0 [preferably] out of an 86-93 engine. Use whatever 302 you can find and this will work. Make sure the car has relatively low mileage. You dont want a car that uses more oil than gas But you cant be to picky about it either you are getting a rocket ship for 800. I did a comp test on mine before pulling it. Part 2 coming in about 30 minutes. Quote Link to comment Share on other sites More sharing options...
Hitman47 Posted March 17, 2005 Author Share Posted March 17, 2005 Ok parts list for a 315hp car I will list several ways to achieve this I will list them as a chart A-E .100" .200" .300" .400" .500" GT-40P=97 1/2 Explorer to present model spark plug clearence a pain in the ***. 61 128 169 195 196 GT-40=90-95 Cobra and all prior 5.0 explorers a better head than "p" when ported. 54 107 157 183 192 E7TE=Stock 5.0 head 59 114 144 156 156 '69 351W 52 103 149 174 183 289 50 97 127 156 165 GT-40 (Y303)=aftermarket 64 114 167 199 213 GT-40 (X303)=aftermarket 53 114 170 207 226 .100" .200" .300" .400" .500" GT-40P 52 90 123 135 139 GT-40 47 94 119 128 128 E7TE 42 78 105 115 116 '69 351W 48 77 100 113 118 289 37 71 93 104 107 GT-40 (Y303) 52 98 128 137 134 GT-40 (X303) 50 106 139 153 161 Comp Cams CCA-31-226-3 is same as ford f303 except flat tappet and only 104.95 http://static.summitracing.com/global/images/instructions/cca-31-226-3.pdf A`s setup is probably the most optimum and if done with more valve train componets springs/retainers/valves it can bea 6000 rpm 320 hp vette killer. But the intakes are harder to find so usually go with a carb and single plane intake for half the price. Explorers are becoing scarce, you can get a whole engine ready to drop in for about 1k. They are great motors they are superior to cobra engines in many ways intakes are better, they are distributorless wich means overall timing is not 36 btdc it is 6-8. Also the cams are b303 stock wich is alittle less steep that .512 lift.

lazycyril Posted April 11, 2005 Share Posted April 11, 2005 ya know if you want to get yourself beat up, the proper way to do it is to join the marines. That being said lets plan on prepping up a 460 power Z Quote Link to comment Share on other sites More sharing options...
Hitman47 Posted April 12, 2005 Author Share Posted April 12, 2005 cyril whats your number again I wanna call you but ive been out of commission. Is it6623793? We will prep your car if you want. Chad Quote Link to comment Share on other sites More sharing options...
hat1324 Posted April 13, 2005 Share Posted April 13, 2005 what trans did you go with hitman? any info on your 9"? I just got mine today Quote Link to comment Share on other sites More sharing options...
Hitman47 Posted April 15, 2005 Author Share Posted April 15, 2005 Im using a toploader but, but would its fine because 6-700 hp doesnt car if you stsrt in 4th Also the 9 inch kit will be out it will be verybadass, we are trying to have the stock spring housing with the stock almost everything. Remember guys solid rears get way better traction all the way around for hi hp cars or else trans am cars the priemer road racers [where irs shines] wouldnt take out the dana 30`s corvette irs [the strongest irs] and put in 9 inchs which may seem to you bowtiers like a sacrelig but hey nobodys prefect Quote Link to comment Share on other sites More sharing options...
Guest iskone Posted April 17, 2005 Share Posted April 17, 2005 Hitman, the build you posted is great but I'm confused. Is there more than one build in this thread?I'm asking because you it looks like any 86-93 5.0 is gonna get you to 320hp with a cam swap. I don't know if the 5.0's are that great but if so cool I'll sell my built n42/e88 for a 320hp swap. Isk Quote Link to comment Share on other sites More sharing options...
Hitman47 Posted April 18, 2005 Author Share Posted April 18, 2005 yes they are that cool man u can puck up a jy 5.0 that you can rebuil for 250 that will run for ever, at 320-380 hp with turbo 400-600 Chad Quote Link to comment Share on other sites More sharing options...
Guest iskone Posted April 18, 2005 Share Posted April 18, 2005 Correct me if I'm worng but I thought the biggest cam one could use with a stock 302 was around 220* because of the pistons. Isk Quote Link to comment Share on other sites More sharing options...
Hitman47 Posted April 19, 2005 Author Share Posted April 19, 2005 sorry milled head is requiered also i was talking about either a built small amount of money or gt40 head. Chad Quote Link to comment Share on other sites More sharing options...
Gollum Posted April 26, 2005 Share Posted April 26, 2005 gt40 heads can be had at a small price and make a big difference. The cobras only difference in motor was upper/lower intake, headers, and heads. Other than that they where the same engine. They were also severly underrated. We never had a chance to dyno my brother's 93 cobra before it was stolen, but I've driven plenty of 5.0 stangs and this cobra pulled like no other. I highly recomend those heads if you can find a deal on them. A GREAT alternative if you have the money is AFR heads. Quote Link to comment Share on other sites More sharing options...
hat1324 Posted April 26, 2005 Share Posted April 26, 2005 there are much more heads then the AFR's for a budget... The 351 heads are a good cheap upgrade as well as the gt40's. And did the cobra have different gearing? Quote Link to comment Share on other sites More sharing options...
TomsCoupe Posted June 3, 2005 Share Posted June 3, 2005 IMO, the best 5.0 engines(if going to use EFI) are the 89-92 engines. The86-88 use Speed density(unless its a california car, in which case it runs mass air which is a good thing) and 93-95 use crappy Hypereutectic pistons. 79-84 -175hp rating -non-roller blocks 85 -first roller block -600-cfm Holley carb -210 hp rating (automatics still used CFI) 86 -roller block -forged pistons -first year of speed density(not a good system) -stiffer block -crappy heads 87-88 -roller block -forged pistons -First year of the E7TE heads which are pretty good for a stock head. -still uses Speed density -225hp rating 89-92 engines(88 california cars have mass air too so they are good as well) -forged pistons -roller cam -mass air(much better than the speed density that came with the 88-below cars) -225hp rating 93 -changed to Hypereutectic pistons -power drop to 205hp 94-95 -HO engine with E7TE heads -Hypereutectic pistons (not sure about power rating) hope that helps Quote Link to comment Share on other sites More sharing options...
