I'm in the planning stages of my 4 link and 9" build and want to know what are the average and best 60fts people are hitting with ls engines. My friend has been telling me to 4 link for a while and with recently destroying the 10 bolt again it seems like perfect time. My personal best was 1.48 on leafs so I want High 1.3s on 4 link minimum.

 

Manni i dont see why you couldnt cut the numbers youre looking for, i dont put near the power down as you when i was on the stock 6 liter, on a 100 shot i was cutting 1.43s <--- being the best!

thats probably 600 to the wheels maybe

 

Thats freaking impressive for a leaf spring... Well to me it is lol cause i couldnt ever do it!

 

Tarninup so what shock setup are you running an im guessing caltracs and what drop. if you dont mind me asking

This is impressive for stock leafs, maybe we should have him post up

 

1.43 is great. Not sure what 15 psi launch would cut but that's what killed my 10bolt last week.

Well your doing it now and on DR which I would try and run on 4link.
Flip kit with Calvert adjustables set at hardest setting with caltracs touching springs.

 

What all did you have done to the 10 bolt? How did the axles look? Good luck on Link and 9"....
