Well, since my dad is a rebuilder, we are always tinkering with something or building some project. He has an 05 Chevy SS Intimidator that's hit in the front. So obviously, it's a 2WD LQ9 6.0/4L60E. He wants to build a bad N/A street truck that he could DD if he had too. So, I sat down and compiled this list of motor/trans modifications. Could you guys and gals give me a estimate of hp/tq numbers as well as 1/4 mile times? Thanks in advance!

I would guess around 480 fwhp (380) wheels. Maybe a 13.3 @ 100 mph.

 

get some lower gears as well..4.10-4.30-4.56. id also get a bigger cam..have the heads milled as well

 

Some ARH stainless headers!

 

i wouldnt do the obx headers, they have small primaries. i'd run pacestters. mill the heads for around 11.1 compression and you should see 400whp. btw i have that stall and its great dd, but wont 60' for nothing, 1.9s...

 

+1 for milled heads, bigger cam, and bigger stall

 

+1! to big cams and stalls!

 

man all it would take for me to make 400 wheel is a milled set of 243's and a cam?sweet deal.

i say hook your pops up. but before you spend big money on converter and building the 4l65E that your 05 has in it. id consider a 4l80 with that and the 14 bolt rear you should have plenty of long time fun..before the g-80 breaks

 

I've had both. The primaries are the same size. And Pacesetters are garbage crap in comparison.

 

not true. obx are only 1 5/8 and pacesetters are 1 3/4
