I am like 10 credit hours away from my associates in mechanical and civil engineering degree. It sucks.. I need like 136-138 hours to have the BA, but I only have like 51. I havent been able to put that much into school as I have been working full time.

Im currently researching the 5.0 stroker kits. I see many people running 12-16psi, but I doubt I would go that high as my truck is more less a DD than a race truck. I will keep looking into it though. I wont be doing anything to my current engine until it blows so I am not rushing into whatever decision. A 5.4 is still up in the air. Just depends on how much $$ I got when I put it in.

I have read JMC's notes a bunch of times. Thats how I figured I would need to change converters. Its not something I dont want to do, but I would rather be different than everyone else with a built 4.6 or something. Huge hp/tq numbers arent THAT important to me. The closest thing this truck sees to a race is stop light to stop light. I do like having the power on hand though, just in case.

My guess would be probably around 200-220 to the wheels with a dyno tune. Thats only because you probably have close to 30% drive train loss. Your edge is not going to make up the difference that upped timing and everything that they can do on a dyno will. Dont mind hijacking btw, I dont mind questions/comments. Its amazing how much power that tires rob from you.
I would like to see the numbers on that man! I have been wanting to compare the max numbers on the whipple/vs 9psi on procharger. What year truck and size engine do you have? If you have PI heads,5.4, or both I am sure you got me beat on the numbers. Not to mention that mine is not aggressively tuned at all. Will be in the future though.

 

Well, I am not sure what to do now. Everywhere I look, I find fully forged 4.6s ready to bump out 600hp for the same price if not a little more than the 5.0 stroker kits. For the price of the 5.0 kit and having it installed and doing headwork, I could have a already blueprinted and forged 4.6 and buy new PI heads. I could probably run 10-12psi with PI heads and lontubes and get another 100+hp out of it easy. All cheaper than what it would cost for a 5.0 stroker and nearly stock heads.

 

just depends on what you want, if thats the case I think I would find a low mileage PI 5.4 with the forged bottom end (I think the only combo with both is a 99'?), add forged rods & pistons and then you have a fully forged 5.4 for cheap, and PI heads right off the bat. There is nothing wrong with a built 4.6 but unless you did the 5.0 kit I think I would go with a 5.4...the torque is a BIG difference, and honestly wouldnt cost much more.

 

actually you can get a ford racing forged crank for $350 new I think...find a deal on any PI 5.4 tear it down and build it up from there for the cost of the 5.0 rotating assembly you could prob have all your forged components for the 5.4 AND all the machining and assembly done...pretty much full forged 5.4 shortblock for the cost of that 5.0 kit. Get your PI heads ported and you would be making a ton of power with the procharger!

 

99 5.4s have PI heads correct? If that be so, should I just buy a really high mileage 5.4 for really cheap? The yards around here have some pretty high mileage 5.4s for cheap. All I would do is take it all apart anyways right? I have heard that porting heads is really expensive. I dont know for sure on that though, and would it be smart to run stock cams on this forged 5.4? I would love to have a forged 5.4 block for 2k, and if thats possible, sign me up to start tomorrow .

 

I say either go with the 5.0 stroker just to be different or if you do go fully forged 5.4 then put a nice cam in there too.

 

Well I will go with whatever will be the cheaper route. Thing is, I dont know how to rebuild an engine to spec. If I buy a 5.4 to build up or get the 5.0 kit to rebuild the 4.6 I am going to have to take either somewhere to be built. The 5.0 kits that allow for 600 hp all push 2200-2600 for just the kit. All of those kits will require me to do headwork on my current heads or drop another $1400-2000 on already ported heads. After that, I will feel obligated to bump up the boost and run longtubes which will run another $800-900 easy not to mention another day on the dyno. All of this is lacking labor costs . However, if I can pick up a 5.4 long block thats generously used for $800 or less then I can pull the heads and ship them off to be honed or ported a little bit for hopefully less than $1000. Plus I can get the 5.4 checked out and add some rods and pistons to it for hopefully less than 2-2.5k. Now that is all including labor cost I hope, or atleast I will be close to the final costs. With that option I will want to run long tubes and more boost, so there goes another grand easy with tuning and all that mess. SO here we go,

Uninstalled 5.0 stroker with ported heads and lontubes=5k
Installed 5.4 with longtubes and more boost=4k.

Now thats very rough estimates.. and either way I am going to be kicking myself in the butt forever for spending that much money on an engine.

 

Well either way you go just take your time man. Choose what you wanna do and buy peices here and there. That is what I am doing. Takes some sting out of the price. I know that it would be bad a$$ to say you have a 5.0-5.1 stroker!! Haha. Just make sure to get all forged internals. What do you have to do for head work with the stroker??

 

Well, unless I want to port the hell out of my non PI heads, I will have to buy ported PI's or buy stock ones and have those ported. I would love to be able to say I am rolling around with a 5.0 and I might even buy a 5.0 emblem . Only thing is that long run wise, its going to cost some serious $$$ to get the 5.0 accomplished and I am not sure if the $$ will be worth the hp/tq gains.

 

You should be able to get PI heads for not too bad.

 

Ford racing sells them complete for $450 a piece. BUT thats with stock cams and everything...

 

damn i made more than that n/a with my non PI 4.6 at around 160K miles

 

Did you have stock gears and were you turning 35's though?? That is where he lost a lot of his numbers.

 

I am running a fully stock non PI 4.6 and a P1SC with 9lbs of boost. I have 10.5" of lift and 35" tires on 18s. The only engine mods I have done are injectors and MAF.

 

i have a 2/3 drop and stock 30" tires. stock long block 4.6 as well im around 185K miles with 8-9psi but i shift mine out at 4800rpm so it usually only will see 8psi.
