Hello,

So I decided to get an LS6 intake to replace my LS1 intake, and I also decided that I am going to switch out my truck 206/212 112+0 camshaft for a custom grind from cammotion. I submitted my form and the rep came back with two options for me. Now to choose between the two. The vehicle it's going into is a 4.8 swap 1986 IROC-Z with 4L60e and 3.42 rear gears. I plan to drive the car in nice weather as a weekend driver, but I also would like to take it to the strip and try it out on a race course here and there. I haven't decided on my T/C yet, which is why there is two options. Here they are:

"I have looked this over and came up with 2 different options for this build. I will start by saying the current springs are fine and putting more than 550 lift in this would not be beneficial.

Option 1:
Moderate idle, work well with 2500-2800 stall and make great torque but likely start falling off after 6000-6200 RPM
215/219 duration @ .050''
109.5 lobe separation, 107.5 intake centerline (109.5+2)
.553''/.553'' lift with 1.7 rockers

Option 2:
Slight lope to idle, work well with 2800-3200 stall and will make more power at the cost of moving the rpm range higher. Pull strong to 6400-6500 RPM
220/224 duration @ .050''
110 lobe separation, 107.5 intake centerline (110+2.5)
.553''/.553'' lift with 1.7 rockers"

Thanks!

 

I'd probably go with option 1 being that is a small engine
