Project 6.0L Sedan

[D_Eclipse9916]

So going with the LS1 now, you should actually have a slight weight savings overall, right?

Are you doing any cam/engine seals/refresh/hi-cap oil pan/etc "while you're in there"?

Unfortunately, that is a bit of a misconception thrown out by swap enthusiasts. WHile the LS1 is all aluminum compared to the iron-blocked S52, the weight of the extra cylinders and the tougher T56 6-speed transmission means that I will be gaining about 50lbs in total. Lighter than the spare tire/jack combo in the trunk. Heck, the weight savings of going from my power/heated vaders at 90lbs a piece (no bullshit, tought to beleive I know) to aftermarket seats will more than offset the 50lbs.

I will be pulling apart it down the bare long-block, and then pulling the oil pan/valve covers. Depending on the condition, I may replace main bearings/rod bearings/lifters. Hopefully will not be needed.

Power mods is tough. In order to get to my goal of 400-430rwhp, I would need to:
1. DIY port throttle body (free)
2. LS6 intake manifold (~300)
3. Cam/springs/reatiners/timing chain (~600) 224/228-581/588 114 LSA for driveability, smog, power under the curve
4. Tune (~200-400)

I could kncok out the LS6 intake manifold and go for a slightly more aggressive cam, but I would like more power under the curve and driveability, while still making my goals.

The stock oil pan will be used since it is needed to fit the motor. I am trying to look up a few mods/baffles as it will probably be autocrossed and maybe TTed once or twice.
