Re: all boltson no go
 

dont feel bad... with everything i have, i only ran a 16.4... i'm blaming my altitude... and i have the extended cab...

Good time for a plug here! RADIX!

What was the weather like when you ran? That is not too far off from where you should be with a 4.8 and those mods....

Ex Cab? Standard Cab?

Re: all boltson no go
 

Have you made a lot of passes down the track? I'm not really sure what could be wrong, cuz you should definitely be doin better than a 16.01. I have the 4.8 right now with ASM headers, Hpp3, exhaust and LT1 fans, and i'm running a 14.9. You have any extra weight in your truck? Shoot...i don't know. Get rid of those shorties tho and get you some ASM headers. That will help a ton.

it is an ecsb i probly should let you guys know that the truck ran 15.67 with out the bbk but i thought it was supposed to help not hurt my times, and when i had the 4:10 gears in i ran 15.10's so i new the 3:73 gears would hurt my times but not the bbk?

Re: all boltson no go
 

i have ran about 30 times and the temp that night i ran the 1601 was about 88

Re: all boltson no go
 

Well i had just a drop in K&n and i ran a 15.2.... maybe just the altitude and plus it was at night bout 75* +/-....hmmm got me?

Re: all boltson no go
 

it's a 4.8 man, you're right on...maybe even quicker than i would figure...fast 4.8 has a bolt on 4.8 and runs slower than you so you're doin ok. plus it was kinda warm when you ran.

Could not aggree more....... :burn:

Re: all boltson no go
