IDK what it does in the 1/8th to be honest, but from a dig if I flash the converter holding the break it does a little better than what you think.

I'd guesstimate in the 1/8th a 8.7X at worst and yes that is with the stock converter too.
Maybe 8.66-8.70 on a very good day idk. Will find out sooner or later.

It's definitely not unherd of for cammed 5.3L RCSB on stock converter to run 13.5 1/4th mile. I know a few guys that did it. Depends on the DA and several other factors.

Truck is not fast by any means lol, just something to have a little fun in. Sometimes videos can be deceiving and you really can't go by them.

A lot of times people think their trucks are fast until they post a speedo video, just remember what I said everyone lol.

I think 70mph -100mph in ~6 seconds is pretty good considering I'm still on the shitty stock converter.

Btw if you have a stockish 4.8/5.3L more than likely it will run out of *** about 80mph. Before my cam my truck ran out of *** at 80mph, after cam kinda runs out of *** at 100mph now with stock converter. Gearing is a factor too though.

Looks like my old truck ran about the same as yours, according to my video, and it ran a 14.020@100.5 with a 2.373 60'. Mods were a Comp custom grind XE-R 224/232 .581/.595 114+0 cam, Pacesetter LT's w/ory pipe and a cutout, 3.73 gears and 26" DR's at the track. Of course IDK what your track DA's are usually at but mine was about +2000 ft. My tune was spot on @ about 12.6 AFR and about 28 degrees timing. I have a dyno sheet, as well but numbers seem a bit to high to most, it had great high rpm power but NO low end obviously looking at the 60'! I do believe this was the reason it was able to achieve such a big peak number.

As you can tell, it made hardly any power below 4k, hell even @ 4k it only made about 230rwhp. Graph is a bit hard to understand but HP is the red line with the numbers on the left and and TQ is the blue line with numbers on the right.



Here's my speedo vid:

that must have been a long *** road, because that took forever.

Thanks for the feedback LS1Freek. I've seen your truck video before I remember it.

Your 14.020 isn't too bad considering the 60', stock converter, and DA.

What did it run with a converter, or did you ever get one installed?

jrmchevyman

Haha it did take a little bit after 110 or so.



Where is your video?

Man, I never did put a stall in with that setup... Although I did install some 4.56 gears before I swapped to the 6.0, it really woke it up, I think if I had installed a stall yet it would have been easy 12's in good DA

Go with a 3200 verter.. You will like it alot, then prob say damn I should have went with more..

jrmchevyman

haha
Yeah I want to see what it can do first with the stock gears, if I'm not happy I will get some 4.10's later on no big deal.

jrmchevyman

Thats what I'm saying man. I'm just gonna have to buy it and just do it lol. All this talk is wanting me to order a converter asap now.
