Mk II (Mark 2)
MK II engines were under development as a race engine, with 2 bolt mains. In Nov. 1962 NASCAR increased its max cube rule to 427. Chevrolet followed suit resulting in the Mk IIS

MK IIS (Mark 2-S) "Daytona 500 Mystery Engine"
Now with 427 cubes the "Mystery Engine" now sported 4-bolt mains, these engines were tested by JR Johnson, Bubba Farr, GC Spencer and Rex White. Johnson won teh 1st 100 mile qualifying race with an average speed 7mph OVER the current record for that race. Rutherford won the 2nd 100 mile qualifier with a record average speed of 165.183mph. Top brass at Chevrolet were calling the Chev race teams congratulating them on their success in qualifying. They didnt even knoiw thatthese engines werent the old "W" Series 409 engines. The MK-2 devolpment team was small and they had built these engines without upper managemnt approval.

MK III (Mark 3)
During the summer of 1963 Chev engineers were looking at the possibility of having a different bore center for larger displacement engines. The MK III never got off the drawing board.

Thats all I could think of lol, there are more. But hast the basic jist.



For the 2008+ GEN 4 engines there are over 20 different RPO codes for the 5.3 itself-I suggest looking at the GM Media Archives for them all.

Here is a good GEN 3 GEN 4 SBC resource

Is ther e a chart some where thats list the different engine ID's and HP? ( LS1,LT 4, ect.. Up to three years ago my newest car was a 1970 LT1. Still having problems identifying with these newer cars.
Thanks,

read above, most of the 1997-2007 GEN 3 and 2005-current GEN 4 power/rpo codes are in the link I provided. http://www.superchevy.com/how-to/eng...n/viewall.html

The engine rpo's this thread is about is listed in post #11.

Anything specific just ask away my friend.

[nelson007]

Thanks Hog,
I saw that, which was of a great help. I was looking for all the engines codes from 1953. Years ago I had one but cannot find it, it was on a spread sheet.
Thanks,

A 2015 mustang gt does 0-60 in 4.4 seconds and the quarter in 12.8. Worst case scenario your friend is just a slightly better driver...

i've seen lightly breathed on 5.0's go low 12s. Make no mistake that car is a serious contender

altho at the 1/2miles, they ran out of gas. Mid 130's is what I recall.

the 2104's run 12.70's. the new 2015's are porkers and most people are getting 13.0's out of them.

but back to my 2012...
-it was a first gear roll race
-he drove it like he stole it because not his car, lol
-geared low
-vvt

I lost by half a car at 85 mph (not safe to keep going)- before I put headers, probably a 12.90-13.00 car at 111-112 at best (street tires). It was close and I had a long rev range, but it just did not have the power in that configuration. Over 100 mp[h would have turned my way. Definitely have more top end with the improved exhaust now. Anyways- we are talking 300 cubic inches in a car that weighs 100 lbs more- a lot of the mustang pop comes from the VVT 4 cam variable timing and the deep trans gearing. 1st gear is 3.66:1 ratio. fifth is 1:1. First gear is 13:1 ratio with 3:55 rear gears. Cheapest 12 second car I've ever owned. My friend was laughing his *** off too.
