Grats again

 

nice times for a 4.8 extendo

 

good job colby, now put that stall in and your there.

 

Nice times Colby congrats.

 

how easy is that stall to put in when you have the engine out doing the 6.0L swap?


thanks guys

 

you need to do what blue5.3 did..... sell the damn 20's!! thats slowing you down...

 

I'm not sure I'll ever get rid of my 20's. I may run it at the track on some stockers or something lighter, but the 20's are staying for the street cruising

 

Congrats and I agree, the 20's are slowing you down...

 

thanks

I talked to a hemi owner that night, he was running stock 20's up front and some smaller drag radials out back. He said with just dropping the 20's off the *** end he picked up almost 3 tenths.....and his best time was 14.0. So I would imagine on a slower truck like mine just ditching the 20's on the *** end would net about 4-5 tenths of a gain
