l59 suggestions hp inrease Hey guys! New on the forum and im from sweden. Hopefully you will understand me anyway lol. So ive just brought home a old truck with an L59 and 4l60e with a shift kit both from a 2003 Tahoe. Wanna make somewhere around 400whp, Turbo and superchargers sadly aint allowed here =/ In sweden these motors arent that popular so im asking u guys since ur the kings of LS hehe. So like som sort of shopping list would be awesome! Thanks! /Robin

With a 5.3, 400 whp is a bunch if you want reasonable drive-ability. My thoughts for minimums (I'm sure more knowledgeable folks will chime in):
Here's a link to more thoughts: Summit Upgrading the L59
Do you need to pass emissions tests?
- a big cam with new lifters and pushrods
- big heads (243's) that have been CNC'd with valve job.. good rockers, good springs, new trunnions
- take it up to 3.89 bore... or start with a higher cube block (5.3, 5.7, 6.0, 6.2 all have progressively larger bores with the same stroke)
- more compression: deck the heads or grab some 4.8 pistons
- get a good intake, injectors, fuel rail and larger throttle body, cold air intake
- long tube headers and free flowing exhaust

How is this cam package in your opinions ? http://bdturnkeyengines.com/53l-ss-cam-option

Thanks man. Need to keep this on a fairly tight budget so the 400whp might be a long shot lol.

Long tube headers or the cam will not perform
