yes, it started out with a set of headers as the only modification.
the same as the US 4.7 started out with, and the US 4.7 had 200rwhp a that point.
230rwhp out of a stock 4.5 is pretty high. i think my old 79 was probably in the 210rwhp range, with no headers and just the mufflers cut off. I would race scot and pull him. I felt bad, since mine was bone stock, but it was CIS and was running pretty well.
Just the intake alone gave some pretty good gains. I would say all the mods are pretty close to even. 10hp for exhaust, 10 for headers, 10 for euro cams 10 for euro intake. As i said, ive done this on a few cars and have documented the results.
scots went from near 200rwh to 290rwhp. my 4.7 US started the same and ended up the same (293rwhp) for the same mods.
both started with bone stock 4.7 or 4.5 liter engines, and ended up with 5 liter euro intake and cams. (with some small trade offs , like scot had the better cams, but i had the better equal length headers, but not to start)
I seemed to also remember the only dyno run where the 4.5 liter showed little gains, was not only for the throttle body being not euro, and also meaning the plennum wasnt euro (i think) but it also had the restrictive exhaust, which I also proved to gain about 10hp in itself just for adding headers.

Sorry Mark, I'm calling BS that a stock 4.5 liter US car gained 19rwhp just by upgrading the intake / TB.
This has been hashed out in at least five different threads. I have a feeling this one is now going the same direction.
There was another thread a long time ago discussing this car. I recall someone saying it also had exhaust work.
The fact that my stock 79 with headers & open exhaust put down 230rwhp really kills the idea that intake only will gain 20.
So just to recap, the 4.5 liter that made 219rwhp was 100% stock engine, stock exhaust manifolds, stock CAT, and both stock mufflers still attached? Only change was the intake and TB?
I've been wrong before.......so who knows?

The 230rwhp dyno my 79 put down was on the same day as an S4 that did high 260's at the rear wheels.
When you say "headers with just he mufflers cut off" so the stock exhaust was somehow connected to headers? That seams odd.
My 79 is a 3" exhaust after the headers, with only two very gradual 45 degree bends, no muffler.

pictures, pictures, pictures.......
Why don't you guys list the casting numbers for the Euro tubes.....?
I have the K-Jet (CIS) numbers for M28/11 or 12:
928.110.297.OR
928.110.298.OR
I do not have the casting numbers for the L-Jet tubes. (I don't have any L-jet stuff.)
perhaps someone would be nice enough to present them?
intake tubes, plenum chambers, throttle bodies, cams, heads, etc are mostly interchangeable---as long as you stay K-jet to K-jet, or L-jet to L-jet.
As I said in another post, the only way to be sure is to check the casting numbers.....pictures are not reliable.

OK Hack---point taken.
Maybe you should have started with a complete set?
Very pretty none the less.............

Thats unusual for a 79. I think Devek had a real strong one before they turned it into a track car, where Petty bought it and painted it yellow. (real nice)
anyway, you said it, i am odd, but there was a reason. I wanted the car to pass smog and didnt have an exhaust system yet. we made a ypipe that ended up with the exact same flange as the CAT exit. (and then made one with a Cat on it too. so, it was headers, off the shelf cat, into the stock exhaust system. 188h up from 175rwhp. did the exhaust system 3.5" with the y pipe and gained 12 more Hp to 200rwhp. Then, we did the intake stuff.

Bob,
I must say, I am a little confused. In my experience, the euro S runners looked beefier and straighter than their Yankee cousins. The pic that Hacker posted is what has me second guessing myself. He says that it is a pic of a Euro S top end. And it does have the twin distributor which is a euro part. The runners in that pic look no different than yours which look no different than my 84 US runners.
So this is what I propose. Look at the casting # on the front passenger side runner. If its a US runner is should read 928.110.213.1R . I hope this helps.
And Hacker, go ahead. You can say "I told you so". I can take it.
