Dlemma, 3 or 4?
Discussion
Best investment
As you've probably gathered from my other posts, I'm in a bit of a dilemma.
I have bought a long block gen 4 engine (being told it was a gen 3 so I got a bargain) and I have also been offered a complete plenum to sump gen 4 with everything but the ecu.
What would be better in the long run as they work out the same in price:-
Fit aftermarket ecu and control system to the gen 4
Fit my gen 4 heads onto a gen 3
Scrap the whole gen 4 idea and just use a tried and tested method in a street rod, stock gen 3.
Gen 4 pro's, VVT, no miles, it's here in england, totally tuneable by a dyno shop down the road,
cons:- never been done before so will need to sort the drive by wire and do away with the canbus.
Gen 3 with heads - Extra power, not a problem with engine management, can get the parts for the conversion, can be done in a day, hasn't been done in a street rod over here yet.
Cons - ship a motor over from states, huge duties, strip and build of engine, more money, if things go wrong, in here and the guys that know all about this (arrow racing and dc perf) are over in the states.
Gen 3 easy install, stock motor, been done many times before in the states cheaper and easier than the other options
Cons - gotta ship a unit in from the states and pay stupid amounts of duty on it.
AAAARRRRRGGGGGGHHHHHHHHH!!!!!!!!!!!!!!!!!
What d 'ya reckon?

Get an LS7, seriously other than the willy waving of a 8.4L V10 and it being a viper engine it has F
c all going for it. Don’t get me wrong i wouldn’t want anything else in my viper but if i was building a hot rod i would want the LS series V8 sound hands down.
Hardly anybody knows anything about the v10 and parts and tuning help are limited to just a few suppliers. Take a look in the summit catalogue and get back to us how many items they have for the viper engine and Ls7

Dont know much on the tech side of things, but I thought if you were to bring 'parts' over from the States, the duty was not too bad? Think its the usual thing, All depends on Bill of Sale 
The duty side of things would depend on the shipping method and how its all declared. I have been lucky on some occasions but i have also been majorly gouged but some of the main couriers like UP-EX. If its being done as a commercial enterprise things will get harder to hide but your less likely to be subject to extra fees and inaccurate valuations the main players make ViperDave said:

Depends very much on what is declared as the value at the time of shipping, but I would suggest that on major parts like the ones likely to be needed, you're going to be hard pushed to get very lucky when it comes to the import duty and VAT which will be added once they arrive.
Don't want an ls as I want 500 hp without having to "tune it" and I wanna be an arse and be different.
The duty wil be 4% + VAT on whole transaction.
How many morris V8's do you see? Loads.
How many morris Vipers have you seen?
Actually, how many cars other than Vipers have you seen with a v10 in?
Also, I want the flat torque curve too

The engines are legit, they were used in development "mules" that's why it has no ecu, they were using a fully programmable one and that's the reason why the truck had to be broken.
I was speaking to a guy who has put a gen 3 in hit lotus 7 style car, he needed a quick remap and to decypher the wiring diag (which I've done) and it's 4 wires, plug and play. I can see where you're coming from but if I wanted a V8, I'd have gone for a blown big block. I had a etwin turbo'd v8 which was monsterous, but I wanted something that would churn out the power I want in stock tune.

Ok perhaps I am being thick or not quite the anorak but with out the inlet and the sump and a strip down how can you tell the difference between a 3 and a 4??
Lol i think you need to resign as el pres if you cant tell the difference by just tasting the oil.
Valve covers are different though, only going to help if they are fitted mind.
Yes the valve covers and intake are different but if these items were missing how could you tell its a gen 4 ??
You see I was tempted by the Gen IV on PH but it is somewhat hard to believe that DC (as it was) sent a mule SRT10 truck to the UK as I understand it US mules are either kept or destroyed in country by the manufacturer due to warranty or litigation issues

Yep... I'm confused too... GenII, GenIII, GenIV... Please post a pic of it with a tin of custard.

I've just been looking at the PH ad for the Viper Engine stating it's a GenIV Link
Correct me if I'm wrong here, but if, as it states "The headers and sump are not suitable for a viper" that would suggest that it's come from an SRT Truck, yes? Now if memory serves me corectly, the SRT Truck ceased production a couple of years ago didn't it? So wouldn't that still be a GenIII engine? And not a GenIV as being advertised?
