Just wondering what your guys think would be the lowest et on the 5.3 motor. My 220 tr cam. and stock botton end. I dont know what my chances are but I'm shooting for a 7.5 in the 1/8th. I do still have a few mods to go before I stop modding the truck. I'm going to up the spray to a 100 then a 125 when I get my tunning, Maby even a 150? If I can get mid to low 7's out of the truck I"m going to leave it be. Just thought this might get every ones .02 on this. Thanx.

 

Well All Motor I Went 7.92 @ 84.00 With Everything In Sig But E-water Pump

 

It's totally doable in a lighter truck.

I went 12.3@110mph with a 5250lb raceweight and a 5.3L.

Flyer was on his 5.3L when he went high 11s@111mph and a 4550lb raceweight.

 

Wow that is awsome. What are you doing about traction? I get with a little gas you could bring those numbers down a bit. Thanx man.

 

I Have M/t Drag Radial With A Little Gas You Could Get In The 11.s On The Edge All Out ***** To The Walls.

 

Hey I heard the pistons in the 5.3's can only take about 425 h.p. is this true. I know I have burnt two pistons up in the past and know I'm on my second motor. I'm kind of scared to push the stock internal 5.3 anymore what are yall doing.

 

I was well into the 500+RWHP range and I never hurt the stock pistons on my last motor. I had a great tune though.

The biggest thing is to keep things cool and tune the snot out of it on a good dyno.

 

Well I dont think I will be much over 425 hp. That wil be great if I do though, Or even if I get to 425. Fine with me. As long as I can run with the camaros and t/as around here that think they are bad *** for a while. If I can get a 7.5 out of the truck I think I will leave it alone and start on another project. Thanx guys.

I wonder about that all the time. My best 1/8th mile so far is 7.48 @ 92.6. There's a guy on here that went 11.63 in the 1/4 and I'm trying to go a little quicker.

 

Grey Silver is my Hero!

Well, now that I am going the nitrous route anyway.. :p
