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.

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. http://archives.media.gm.com/us/gm/en/index.html Here is a good GEN 3 GEN 4 SBC resource http://www.superchevy.com/how-to/eng...n/viewall.html |

Re: LS1 vs.LT4 vs.LT5 vs.LS6 vs.LS7 etc. discussion continued
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.

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. |
