tibbs.james 1 Report post Posted September 4, 2007 Well I have located a 318 at a secret place that i wont tell you. its a 318 auto Looks to be FL but hard to tell as only had a quick as look and all bumpers are missing. I was wondering what ratio it is possible for the diff to be 4.27 and 4.1 spring to mind ? Anybody have any info on this? Quote Share this post Link to post Share on other sites

hotwire 352 Report post Posted September 4, 2007 now next question what is the easier way to find out if its M40 ? If its a facelift car it will be an M40 engine - looks like this... Quote Share this post Link to post Share on other sites
tibbs.james 1 Report post Posted September 4, 2007 rats That makes it non facelift non M40, as above only had a quick glance and was missing many panels. So i know its an M10 Auto. What does that make for the ratio ? Quote Share this post Link to post Share on other sites

What does that make for the ratio ? Probably 4.27, but maybe 4.10 still? Quote Share this post Link to post Share on other sites

Silver Fox 43 Report post Posted September 5, 2007 M10 318 auto = 3.9:1 M40 318 auto = 4.45:1 Of the 5 318 f/l auto's I've wrecked, 3 have been 4.1's, other 2 were 4.45's.the only 318 m10 I've done was a med case 4.1. obviously some could have been changed, but the most common source for 4.1's I know of are 318 M40 autos.

tibbs.james 1 Report post Posted September 5, 2007 ok well im going to get under there and check ive decided because if its a 3.9 or 4.1 i will buy it. now the name plate with the numbers on it. Does it plainly tell me the ratio or do i need to know the last 3 numbers to match up to the list or something how does that work? Quote Share this post Link to post Share on other sites

Name tag (lower left) has the ratio in straight forward read, probably need to clean up first to be able to read it Quote Share this post Link to post Share on other sites
