I'm getting closer with it. I'm going to try to post up a log at least and possibly an in truck video. I'm honestly only hoping I can get a torque curve something close to yours. I'd like it to be a bit flatter like my truck is, but with stock manifolds, stock cat back, stock y-pipe with cats, and stock air cleaner I'm expecting to lose a bit in the higher rpm. I also need to check fuel pressure tonight as I think I'm losing some at higher rpm. I'd be done right now with tuning if I could have gotten the wideband sensor in it. Both rear O2's are stuck in there like they are f**king welded in there. When I get some time I'm going to fix that here at work. The current torque down low is increadible. The Ho has a 3.42 gear and at 70mph turns about 1800rpm. At 1800rpm I can accelerate up hill very well in the big machine without getting past 35% throttle or unlocking the converter. I'm not allowed to change the exhaust though until I fix some other issue's with the Ho per the wife. As it is I now have the lope almost all gone. At a 600rpm idle it barely lopes at all. I really have to add cruise control to it and then she won't mind me changing the exhaust. Everything I have is fairly loud and it gets old to her.

i love my tr220 in mine, its on a 112 but i can't imagine the 114 is too much different, i have a heavy truck and i tow with it and it pulls hard to about 6200 then starts to taper down quick. I pulled my buddies 02 ext cab 4x4 to hinckley the other day and got 14.5 mpg on the way there at 72mph and tons of torque at 2000rpm. I would like to get to the dyno some day, still working on the tuning though.

No offense but unless you compare only 5 speed vs 5 speed your numbers mean nothin. Most the guys on this board are goin thru a auto which will have more loss no matter how you look at it. roughly 8-10% more so in all honesty your tq numbers are average and your hp is pure junk. JMHO.
I still say put the truck on the track and let the combo prove or disprove itself.

Up next is a 224 single pattern cam with a 114 LSA. From who I haven't decided yet. Nothing else changes but cam and tune to accomodate new camshaft. I'll create a "part 2" to this series when that happens. Winter is coming though and the truck only has a week of insurance left on it Probably have to wait until spring

I would stick with that Comp Cam you had already picked. Trust me you'll like it.

I donno about anyone else but Im stickin to the meaty side as Zippy is leaning towards. Im goin a little beefier with the TSP MS3. Love the sound bites I've heard so far and it looks to have some very nice gains. I put a 221/221 in my 4.8 and never looked back. I havent really had a problem since other than it came down to the shot at a 6.0 or tuning the 4.8 and I bit the bullet

eh I think the 112 lsa would idle too rough for my liking.

This is in my 5.3L. I have alot less compression than you which doesn't help either as well as those clips were after spending the week driving up and down Las Vegas Blvd. That's hours of idling and cranking all the way up to 2k rpm or so. Getting a sound clip of the Tahoe soon, but that thing is almost as smooth as a stock Z06. With the compression and cubes, that 224 on a 112 could be passed off as stock to some.
