First up is a set of PRC stage 2.5 5.3 (862) heads. They come with PRC dual springs with Ti retainers. They have been milled down to 58cc, heads have 30k on them, I asking sold















Last is my Performabuilt 9.5 converter 60e. I was sold to me as a 2800, however it acts more like a 3600 behind my H/C 4.8... I am asking sold.







All parts were removed from my 4.8 and all parts are in good working order.

 

Ill take the udp. Give me your paypal please.

 

How much did the heads help your 4.8? I've been looking at a set of these to put on my 5.3.

 

Payment recieved. Thanks

The heads helped out alot on the top end. The added compression from the 58cc chambers combined with a .04 headgasket really helped with the TQ which the 4.8 really needed. I would same with the right cam these heads would work great on a 5.3

 

Pics have been added.

The tc has 300mm stamped on it however it measures ~9.5. Weird yes.

 

Yes....the performabuilt is a 9.5 and i found mine to be very loose also. Took some getting used to.

 

Heads are pending...

 

how much difference is this converter compared to a tbss converter? im not too familiar with them. how many miles were put on it, and any videos with it as well?

 

How many miles on the converter?
Where does it flash with your 4.8?
I have a 6.0, so if it acts like a 3600 in yours I wonder how it would act in mine.
Also has the converter ever been cut open, or been in a bad trans?
I am interested in it.

 

The converter has about 25-30k on it. It came out of mymtrans i am still running. I swapped to tighter cirlced TC. It has never been in a bad trans so the TC should not give you any issues. Also it has never been cut open.
