V8 Conversion

Check out coloradofans.com and 355nation.net they both have lots of info. The factory actually put the 5.3 V8 in colorado's starting for the 09 model year.

as far as power...the 5.3 does get more torque and horsepower....but as far as 1/4 mile times ...there really is no difference...the 5.3 is a heavy motor...it does get more pulling power though

"as far as power...the 5.3 does get more torque and horsepower....but as far as 1/4 mile times ...there really is no difference...the 5.3 is a heavy motor...it does get more pulling power though" this is not true. the 5.3 was available on the 08's as well it only weighs 37 pounds more than the 3.7liter in line five. and as far as a comparison. my grandpa has a crew cab 3.7l 09 i have an08 crew cab with the 5.3 and we can line up and he will punch it and i cant take off at three fourths throttle. it is way faster than the i5s

really the only performance v8 colorado ive seen is the colorado ss but it dosent look like chevy is goin to release that toy is in the foreseeable future. so when i get the chance im just goin to drop an ls2 and call it a day. :)

There is a company making a Super Charger for the I-5. About $4500.00

Haven't heard of one for the 04's. Chevy dealers have brand new 5.3's complete for around $2600. You still have to buy the computer, wiring harness, motor mounts (kit available for about $700/$900. I've heard of a company in Fla makes them and accessories kit for about $700/$900. available from dealer. You also need front springs to handel the extra engine weight.

I have seen a LS3 in a Colorado. It was a bit extreme but had a lot of power and did require a new rear-end and four link suspension.

Anyone looking to buy a 2012 Colorado 5.3 crew can

I am working on installing a 5.7 in a 2004 2.85 speed Chevy Colorado does anybody know what bell housing I need to change that over

I wanna put a 5.3 in my 07 3.7(blew up) canyon let me know how it works out

Anyone knows if a 4.9 V8 fits on the original 3.5 tranny?? I need a new engine and the original 3.5 is too expensive for my pocket and i jave acces to a v8, but i need to know if the transmission fits or there is no point in swapping it
