I managed to get a new Boss rack about 6 months ago. I do feel lucky. It was found at one of the big stocking warehouses that some of the smaller parts sellers use.

Taking the engine out from the bottom works great if you have a lift. The car has to be quite high to roll the engine out from under it. in the driveway, I would cherry pick it from the top. If you have limited experience pulling one, take your time and lots of pictures. Label bolts in bags...

If you have a two post lift, it’s easier to drop it out of the bottom. If not, google 4.6 lift plate. I’ve “heard” that the 4.6 does not really have good exterior bolt holes to mount lift chains Without potential damage. That being said I never tried a top pull, so do not take that info as gospel.

So my 210 Mustang race only NA car is getting a Haltech. I'm tired of the bastard 2010 wire harness. Its basically a 2009 engine with a 2011 wire harness, give or take a few cams, etc . Anyway, I am trying to figure out how to wire up the IMRC and MAF. I need to know what each wire needs and...

FWIW, I am running this pump in my 2010 E85 4.6l NA Race car. Two seasons and no issues yet. Unfortunately for us 2010 owners there are not many " clean bolt on" options in a lot of performance parts areas. Its likely best you try to reuse your whole fuel pump cradle or at least the fuel...

looks like you are having trouble lining up the hole. One of these spud wrenches could work if you have room...

Gen 1 F150 Intake manifold is black and the Mustang is grey, unless you have a GT350 engine.... Much more detail in attachment.

Heh. You might think I’m nuts, but more power is not always a good thing. I have to put it down in less than ideal situations. Bumps, crappy asphalt, in the middle of high g curves, etc. I need great control of the power over the entire rpm range. Too much power means I only have my little...

Great info on the dyno runs Dino. Its obvious I can get what I want from the 4.6, but it comes at a pretty high cost. My build is at the heads, cam, bottom end stage. ($10-15K?) I think Ill be patient for a bit and see if I can find a Gen1 5.0. I still have some improvement I can do to the...

Lets start with the most likely candidates. If you noticed the trans slipping when in gear before the failure, you like have the trans as the source of the problem. Another possibility on a drag car is a busted flywheel. Try removing the few bolts that hold the transmission inspection cover on...

That’s an interesting thought. 3.55s @7k rpm get me to 75 mph. 3.31 go to 80mph. How much extra torque would a stroke kit give me? Oh, and rulebook say anything over 5100cc is a 10% penalty; gotta avoid that.

5.0 is a bit heavier. It does have two more cams. Turbo/supercharger with intercooler is a lot more weight. Plus it’s more things to go wrong and provides more HP than I can use. I’m really trying to keep things light and simple. If money were no object, I’d likely just built a 4.6 and go...

I’ve never driven a well built up NA 4.6, let alone know how reliable they can be. That is part of why I’m on here asking. Everyone either puts on a power adder or does the 5.0 swap. I’ll have to research the costs using your handy notes above. I appreciate the input

Heh. Yup months would be the timeline. 10k is way low, as I would want to ditch the whole stock wiring and go standalone megasuirt/ or Haltech. Maybe beef up the stock trans too. Luckily the car is stripped, so no accessories to worry about. Stand-alone Abs,EPAs, engine control and a dash...

Thanks Dino. Sounds like I am pushing my current setup to the limit and the next steps get spendy. I need to mull over putting the money into the 4.6 or swap it to a Gen2. I think the final costs will be close.

Does your car still leave two black marks? Does it smoke just the inside tire on hard right turns? If it does the latter you may want to rebuild/replace the clutches. If you do, make sure you get the carbon clutch disks(3L1Z-4947-BE). A truetrac is a good alternative if the carbon clutches...

Already upgraded the oil pump. The rockers gave me 46 more hp above 4800 rpms, but taper off above 6300. I agree with you on the head and cam change. Has anyone spun a stock bottom end(rods, crank, pistons) that high and how long did the engine last? The more I think about it, the GEN2 seems...

Can a 4.6l be spun to 7500 (no more than 7800) "reliably" for short periods of time? Likely only be at those revs for no more than 10 seconds. Can the hydraulic power steering take it? A/C is deleted. This is for a dedicated autocross only car (2900lb SCCA CP car). I have lots of decent...

How close it the top of the wheel to your front struts? Mine is so close I cannot get a pencil in there. If you have more room than that, try a smaller spacer. Be careful of full lock turns, as you might rub the inner fender liner.

I did confirm my (2010) car will start with the ABS connector unhooked. So I will try to graft in the 2005 ABS computer (block and motor too). I will not hook up the CAN wires. Should be interesting to see how well it operates as a stand alone system. Remember this is for a race only, not...

1st image post is a 2010 ABS connector. Note the middle row does not exist on the connector The 2nd post is a 2005 ABS Connector. Note the additional wires on the 2010 for the Steering position and Yaw sensors.

Good point. Let me see if I can get it to fit in a doc.

NM - Found them. Now I just need to get it installed.
