Hey guys,

I received my latest Super Chevy Magazine in the mail yesterday and thumbed through it to find a great tech article on the 5.3 truck motor.

I am new to this forum but am on several others. I bought a 2001 short cab step side about 4 months ago with the 5.3 and I love it.

The article impressed me!! They took a junkyard 5.3 they bought for $800.00 and put it on a dyno to get base numbers. Completely stock with long tube headers and factory tune (no accessories on the front), they got 345 horsepower!!

With a tune, they got 357 HP. They did a mild cam swap and added a set of Edelbrodk heads and got around 440 HP!!

They spoke very highly of the little LS and acted surprised themselves.

There was a comment in the article I want to confirm with you guys. They said an iron block 5.3 could be bored to a 5.7. Is this true??

Anyway, worth reading.

PS: I have a big block Camaro......I think I've been hotrodding the wrong vehicle!!
