I drive a 2000 Silverado z71 with the 5.3. The performance shop I use quoted me $2500 to install a better cam, torque converter, valve seals, and a rear main seal. The cam and torque converter are for performance, but the rear main seal and valve seals are needed because mine have went out. He said it would be $2500 for everything, parts and labor. This includes the price of a tune. I have no idea how much this stuff normally costs so do yall think its a good deal? My truck has 270,000 miles.

 

I do my own labor but that is probably a low-fair amount depending on what torque convertor you go with if that includes parts and labor. The convertor alone can cost $800-$1300.

 

Cam/springs/pushrods--$700 or so
Torque converter $200 (Trailblazer I6)-$600 (Circle D)
Tune $450


It's not a bad price for labor. Only concern is how long that motor and trans are gonna last after you go through all this work. Might want to consider getting a lower mileage motor, doing everything yourself on an engine stand, and then just paying for a motor swap.


Also, the trans. At least get a Sonnax 1-2 and 3-4 servo kit. But this is another question of how long that 270,000 mile 4L60E is gonna last behind another 70hp.

 

 

I modded a motor with 165K on it and it popped right at 200K. Guy has a point.

 

Depends on the exact parts, but that sounds fair for all that.

I didn't see valve springs mentioned though?

 

That sounds fair. I would look into do lifters too. At 296,xxx mine werent bad but i wouldnt have used a new cam with those lifters. I think i paid right arounf 2500 in parts for mine, thats cam kit, springs pushrods, ported and polished heads, cam bearings all new gaskets. i do all my own work and get free fluids through my work too.

 

i did mine at 296,xxx and 10k later and no issues. id say do it and never turn back
