i have heard i can pull junk yard 6.0 heads and put them on a 5.3. Is this true and if so any big modifications needed ?
Austin03Avalanche said:I agree completly with no replacement for displacement. I would love to have a drag truck truck but in all reality 6000lbs is alot to haul. So im trying to make a head turner not bust the diesel club that have took over all small block owners bragging rights in my lil town. I just wanna play a little. i have a garage at my disposal and a grandpa who can build any small block but these LS motors leave us scratching our heads. We aint use to all this computer controlled HP
Yes that is a thottle body spacer ,and believe it or not i swear by that. you can notice a difference between 3-5000 rpm. and the headers are shortys.mikeyjm1 said:If TBS is a throttle body spacer, I'd probably eBay that to someone you don't know. They don't work on these types of intakes.
What headers? I'm gonna potentially start a fight here but LS engines respond better to long tubes.
You already know the tuners are pretty limited. I had a Diablo Predator. It would remove TM but still had limits.
You can use several head castings but as said, on the dish Pistons of the 5.3, you will need to shave them a lot to get the compression up.
Good news is most any other LS block will fit. They're all the same size of the outside. Or most 5.3s can be bored to 5.7 and use off the shelf 3.89 Pistons. Or the stock 3.78 bore can take the flat top 4.8 piston. So much of these motors are the same that the combos are almost endless.

Randy said:Yeah, the torque management kills off the line performance. Get it tuned by Nelson or Black Bear, both do good work and can help.. It's hard for a 5.3L to get a 6000 lb load moving quick, a few bolt ons and tuning will help, but only so much.. At the end of the day there's no "replacement for displacement" (love my 8.1L) and a lot have swapped in a 6.0L or 6.2L and love it.. Or maybe put on a supercharger..

Good to hear from you, where have you been??
Oh, that is terrible! Glad things are on the rebound!ms38w said:I got real sick several years ago. Ended up costing me my job. I eventually got better and got my job back, but I lost a lot.
