If you do take them off would you give me first shot at them?

 

I am guessing it was before the 6.0

 

This is a questions I've wondered about for a while now too.... just how much is gained from good long tubes on a radix truck. Good topic Gonz.

This was early on. Still 5.3. My first mod to the truck was the radix. Second was the Dynatechs. Stock 5.3 with maggie to long tubes netted me the 14.2 to 13.8 et's.

 

Tex there you are,just yesterday I looked at your current posts and it has been awhile.I sent you an email reguarding Jim,you must not have got it because you would have responded.Feel free to write.

 

Gotcha!

 

I'm running shorties and our setups are similar. I think after you make those changes you'll be fine

 

yep, same with me as BC. I had the radix and a 3.0 pulley(5.3L) for a very short time and then I slapped on the dynatechs. I lost about a 1# of boost. I personally felt slower in my launches and low end WOT, nothing to prove this, but top end pull, ESPECIALLY 60 to 100 was waaaay better. No tuning in that change.

 

Well I had the radix and a 3.0 pulley(5.3L) on before I had the headers, No dyno but did run it at the strip before and after, I put the hole kit on supermaxx headers, Hi-flow cats and 50 flowmasters with large pipes, I lost close to two pounds of boost, No problem still running 9, The headers sure didn't do what I thought they would and if I could go back the headers where not ceramic coated, Man I wish I would have had that done
