      Wow, someone is really throwing some money at this. Very good. I look forward to the dyno results. Did you do anything with the heads?

      What sort of intercooler is being run with this set-up? Does he have Meth injection?

      Psst, he likes to pump his oil into the exhaust. That water would make white smoke, or gray with the oil.:p:

      Okay, compression ratio this motor is set-up with?

      Pumping oil in the exhaust is my specialty!

      So SVO, you start with a 4.0 SOHC V6, sonic tested and bored it way over, add custom pistons and rods and top it off with a Vortec. Nice!!! Been working up a plan and accumulating funds myself. Was thinking normally aspirated, built bottom end, head work (similar to SuperSix heads) and custom cams. The really hard part, actually two hard parts, is keeping it registerable in CA and finding someone willing to do my wrenching. Any interest? I've talked to many builders. Either no experience (I don't trust their abilities with this engine), or like Saleen, a V6- maybe in a Mustang but not a truck or a truck would be OK if it was a V8. I have the knowledge and ability myself but lack the space and time.

      Jake, the work you did at the beginning of this thread has been invaluable to all of us trying to squeeze the SOHC. Many thanks. Even though I can't go turbo, I always gleen significant information from your build threads.

      How long will it last?

      A very nice assembly and installation! My concern about investing in the SOHC V6 is the weakness of the rear timing chain guide. Have you found a way to beef up the traction side of the rear guide assembly? The OEM part has no metal reinforcement and can shear off from fatigue.

      Sounds good. Good work!

      I guess this means it's my turn?

      2000 - It's not a problem on all the builds I've seen on the 4.0 SOHC. I've got a lot of miles on mine pushing it pretty hard...no problems except for the dumb scavenge pump problem I faced earlier in the thread. (which is now fixed)

      I actually learned a lot about the terlingua mustang. I admit, I had no clue about this mustang version until you posted in this thread. 2000 - basically, on customer request, they send a v6 mustang down to a town in Texas. When it's done it comes out looking like the mustang you see above. It uses the 4.0 SOHC and the guys doing the work are......I'll Let SVO tell you.

      I hope the data in this thread, that I started years back, helped you. I just wish I could have done it when I said; However, I want to stay married. LOL

      You did good, it's not going to be easy and there will be the "debug" stage. I just hope you tell us what DOESN'T work, if you find that. Most will not. I on the other hand have no problem telling, or typing..documenting, what I've tried and what the results were. That's what the forums are about...but the money seems to get folks. That's okay, nothing is free. And if someone really wants to do something like this, then they should do the research. So I know what you're saying.

      What's the compression ratio again? :)

      One more thing. I always thought is was "not allowed" to mig weld on safety cages, or is that in certain classes? I know my bud just tig'd his entire dragster (100 plus hrs) because that is the rules in his class.

      I agree with what you said in your original post regarding Morana, even if you did end up editing it all out. That guy makes some shoddy stuff. I haven't seen many results from Supersix so I cannot speak much about them but there have been a few things I have seen that left me questioning their knowledge and ability.

      good news....

      "Hey guys just got off the phone with MMR and the prices include: $700 pistons, $500 rods w/ bolts."

      http://www.mustangcollective.com/showthread.php?t=35836

      "Due to the large demand for forged internals we have worked closely with Manley Performance to produce a custom forged V-6 Piston and rod combination, they are made of 2618 alloy for the pistons and 4340 forged steel for the rods, this combination can handle up to 700 RWHP!! and is a direct replacement for the factory parts. The rods include ARP 2000 bolts and the pistons include chromoly steel pins, they are available in all compression ratios too!!

      How about a crank? For that kind of money I would be shooting for more cubes. The 302 stroker kits run about $750 for a balanced assembly, crank/pistons/rods/rings etc.

      The stock parts dimensions typically are not ideal for high performance. Meaning the pistons are very tall, they have a lot of meat in them, which makes them very heavy. A nice competitive 302 kit makes more power just from the weight savings.

      I know I've asked this before, but has anyone checked on the differences in dimensions between the 4.0 and 5.0 engines? There are so many various 302 combinations of pistons deck heights, you might find one that can be fit into the 4.0, if you can come up with a good crank. I think the crank might be the tough part. The best available crank besides the custom pieces like SVO etc use, may be to turn down the Ford crank.

      up to 12 LBS of boost now. Let's see how long it'll survive. So far so good...

      I guess I'm lucky. So was James and so was all the mustang crowd that has done this..LOL

      Guess what? I'm in Texas where it's been 100 plus outside for a month straight! And I'm upping the boost! hehe

      I am re-tuning as I add boost. It's pulling hard as heck.

      Yeah those RPS guys are a hoot! Some of the ignorant tech talk that comes out of the mouths of people over there makes for great entertainment. Like the guy who is trying to fit an Eaton M112 onto a 3.0 V6 Ranger....because bigger always equates to better.....Uuuuuum, yeah......

      Looks like our local track just shut down last week so I may take that offer. This local track has been closing, reopening, closing, reopening for awhile now.

      I'm currently adding an exhaust cut-out and meth which should get me in the 12's. (crossing fingers)
