I have a cheap cost effective option on my NPI 2v. It uses a PI manifold from a 2011 crown vic and a V10 Triton dual 57mm Throttle body and 2 phenolic adapter plates to mount the two together. It looks like a composite plastic copy of a Bullitt.

[@yeanah2571]

Interesting. Just bought an 03 Crown Vic a few days ago, didn't know some of this stuff was an option. Didn't know the 6.8 had a big TB like that

[@madmod]

@@yeanah2571 Yes sir! The v10 shares the same Twin blade tb as the 4.6L 4v Cobras and the plenum/elbow has all the same vacuum ports and even shares the tps, and iac valve. The only thing you have to delete is egr. The plenum is ultimately going to be used with my Victor Jr intake manifold as a cost effective option for a 6061 sheetmetal plenum but I ran it on my pi intake swapped 1996 gt. It replaced a 04 crown vic plenum that I ported to 75mm on the inlet and turned into glorified tinfoil, ran with an aviator 70mm throttle body. Both run very good and better than stock but the dual blade plenum is more noticeable past 4000rpms. Pretty cheap mod for power gains when done with a pi intake swap but money is probably better spent in gearing especially on a big Vic!

[@RJon2006]

Stock PI intakes are the best intake for most mild 2Vs making under 500w. Eddy for the big power 2Vs. The other benefit for the PI in real world driving is the lack of heat soak. Nitrous on stock PI manifolds is fine, just don’t spray over 150 and don’t spray under 4000rpm. Good video. I was pleasantly surprised at how the bullitt did. I thought it would have gained more than it did up too even on the mild cam.

[@A.J.1656]

The Bullitt had different exhaust, intake manifold, throttle body and pulleys and depending on sources was only rated 5-15 HP more than the GT. It's not too surprising that the intake alone didn't produce a huge gain. I just pulled my Bullitt's motor for a rebuild. I got some ARH long tubes and x-pipe and I'm planning on TFS heads and cams. Oh, and I might sacrifice a complete Cobra engine to Build it on a Teksid block with a forged crank. Haha

[@rickstorm4198]

@tigerlock.... Nope since they moved the intake valve it changed valve timing events..... In order to fix that a cam needs to be machined for it. Any P.I. Head cam will retard the cam timing events. Cost anywhere from 15 to 40 hp depending on combo. I saw this issue day one in my head. I worked in a performance machine shop and was astounded nobody caught this issue.

I love the test.. just wish it were done on a real PI headed shortblock.. beggars cant be choosers though :-D

[@madmod]

Pi heads arent all that. 90% of the improvements from the full pi swap comes from the intake manifold and cams. The rest of the gains are primarily the bump in compression which if matched, the npi will produce similar HP. The PI heads really dont flow much better than a NPI and both are pretty lethargic. When you consider the PI has 13cc larger intake ports (159cc vs 146cc) that average only around 10cfm greater flow across the low-mid lift range and actually less high lift and peak flow (160cfm @.550 for pi, 175cfm @.550 for NPI), it looks less appealing. You also have to realize, the npi head has a single angle valve job vs 3 angle with a PI head and you start really seeing the issue. A matched valve job will produce greater average and peak flow numbers out of a NPI than a stock pi head despite smaller ports which means the head has better port velocity. The guys who actually know how to port npi's like Renegade got similar flow numbers to MPH PI's but do so with swirl dams in place making a far more efficient combustion chamber vs the pi head which is already detonation prone due to the plug inserts you have to run on almost every casting. Non PI's benefit from thicker decks, deeper combustion chambers that allow huge ptv compared to a pi, and even use the same pi valve spring just installed at a shorter height which allows for more valve control at a cost of max lift before coil bind. You can fit cams with such a tight ICL in a Npi that would bend valves on any pi combo regardless of degreeing and that is more conducive for power production. Johnny Langton went 12.98 @103 in a 3700lb thunderbird on renegade ported NPI heads, stock shortblock at 9.3:1 compression, stock pi camshafts, stock pi intake manifold, while running through a 4r70w automatic.

I am trying to get s seat cutter that is identical to the seat dimensions because these valve guide seals also have a metal spring seat to keep the springs from searing into the aluminum head ? if the cutter is not perfect the valve guide seal will not sit correctly and the spring sits on the valve guide seal. would you need to machine the top of the guide and run a seal directly on the guide and use a metal washer under the springs to protect the heads ?

we installed new springs

[@mathewhoffer4541]

@@richardholdener1727 yes aware you need upgraded springs but they say the NPI heads cannot run .550 cams without spring pockets machined or custom retainers that add clearance so there is no coil bind ? most likely if you did not have the spring seats machined you got the special retainers and locks with the springs ? the probably just told you you needed them and did not explain why ?

Crower Offset retainers to run PI aftermarket comp cams in NPI heads if spring pockets are not machined

Can you run non pi heads from a 98 Romeo on a pi block from 04 Romeo. Both 2v engines. I'm stuck in a position to need to run this setup if possible. I cant find any info on this particular setup. And why would you right lol. Well its what ive for good parts from two engines. Has anyone tried it? Encountered any problems?

I've run NON PI short blocks with PI heads

Is the truck intake a stock intake? If so for what years?

the truck intake was a stock intake

4.6/5.4 2v big bang!

[@randolphniles2332]

Don't see a svo intake for the test

[@niknasstie]

@@randolphniles2332 i didnt know svo had an intake manifold for the 2v. I would like to see what the lighting intake manifold no blower does even with out the intercooler. Almost everyone with a turbo lightning just keeps that turkey pan. When i go mid mount turbo I plan on removing the intercooler for a rear mounted one and seeing if i can have a runner turn down and then back up to make it a long runner for torque. Theres alot of room in there

The 5.4 3V is Jasper's biggest selling reman engine because they go bang *without* going big.

[@niknasstie]

@@jamesgeorge6551 its hard to just pick one engine anymore. Ive seen two 3v's in the 300k miles with just waterpump, alternator and one had the chain tensioner done because of the noise it was making being loose. Then ive seen LS go out under 100k. The ecotech piston recall at 10k and then 10k after that 🤣 almost every fiat chrysler ugly step child i wont even look at when im huge cuda and Fury/440(the car and engine). the first 2.0 dart engine i took apart and seen theres a oil transfer brick because someone forgot both sides of the head need oil i lost faith🤣

[@jamesgeorge6551]

@@niknasstie Yep. The owner controls how the engine is maintained. I've also seen "good" engines, well maintained, die early too. My shop maintained an expedited shipper G1500 GMC with a 4.3, that had 2 water pumps, and the lower plenum gasket replaced, it had 776,000 on it. It was getting its 3rd 4L60E rebuilt. I used to drive a Volvo 740 Turbo wagon that had 441,000 when I sold it. My neighbors 04 Tundra had 377,000 when it got totaled.

only the replacement ones had alum X overs

[@BluSteel64]

@@richardholdener1727 I put the replacement alum x on my 01. After a year of not driving it much after buying a 99 cobra It started leaking at one of the factory bolts and leaked into the front sparkplug well. Now the sparkplug has rusted to the point it won't come out. I don't know how long this went on because it was a minor leak but I'm afraid this leaked on to the Piston. Have you heard of anything like this before ?
