Im dropping a cobra engine into my GT this summer, and i was looking at 99 cobra engines and 03 cobra engines... there isnt much a difference in price and the 03 cobra engine has no supercharger, is there that much of a difference in the base engine to buy the 03?

Where are you finding this? The 03 is all forged, the 99-01s are not...may have a forged crank.

i'd like to know where you are looking, cause there is a HUGE price difference between the two engines. & even more of a difference in the make

What planet are you from that there is no difference...plus 03-04s came with an eaton roots type s/c. Maybe the particular one your looking at was stripped of it's eaton. Also the 03 engines are forged. And can hold insane horse.

i decided to list the major difference in the make of the engines

99/01
aluminum block
hypertueic pistons
hypertueic rods
mildly forged crank

03/04
iron block
forged manly rods
forged mahle pistons
forged crank
different heads (due the the s/c)
& of course the s/c


there are more differences, but i thought i'd just hit the major ones for you

Yea the heads are actually the same as the 03-04 mach 1s, the difference is in the cams...03 cobras have blower friendly profiles. 01 heads flow about 30CFM less than the 03 DOHC. If going N/A then the 01 is your motor due to a high compression (around 10.1-1 I think) if going with FI the 03 is your choise HANDS DOWN. Good info BTW^

2003 cobra block is iron, not aluminum. There is a big weight difference between the two.

Comparing the engines I could see the prices being Close due to the Aluminum Block on the 99 01 = big money. And Forged internals on the 03 = Big money.

nope, the money shouldn't even be close. unless of course someone is trying to rip him off on a 99 engine, or someone doesn't realize what they have in the 03/04.


& hotstang331 thanks for clearing the heads thing up for me, i should have been more clear with that
