2009 5spd with the original 3.7 @ 173k ...spent the last 4yrs & 70k debating whether or not to attempt the elusive v8 swap (given i've only seen one guy who got it working right)

i'm in this camp. that's why forums have search functions.

simply subscribing so i can find this later. if our 3.7 has a bad head gasket (and i can reach Shawn Townsend regarding his OS), a LH8 might finally be our future.

yep! it all depends on what use it's seen. ours got to where the pedal had to be on the floor for it to disengage; turned out the slave started leaking if it got real cold out. that was at 150k miles. i put a whole new setup in while it was apart & discovered that at some point before 102k...

may as well get plugged into this thread... i remember from YEARS ago that it had lots of good info, and if this 3.7 has a bad head gasket, then a LH8 might be in our future. ...assuming we can find that ONE guy who ever got a v8 swapped manual to work out right with the tune.

well that & the Magnuson is a roots blower while the Whipple is a twin screw (two different supercharging methods). i ain't seen the measurements of the intake plenum or intercooler brick on the Whipple, but the MP & TVS style Maggies usually sit the intercooler really close to the intake floor...

part of it's availability. this tiny glass cost 50% more than my Sierra did a couple months prior, and it's because the GMC windshields were a dime a dozen in comparison. Safelite did the Hummer for $300 & we've been happy with the install. blue fade on top as well.

we'd checked all the standard stuff to no avail only to realize months later that the plastic vent (behind the tire mount) was loose/wiggling.

yep, thanks. i was coming back here to confirm & concur with your diagnosis (for anybody else who's answering the same problem)

it looks like you've got taller tires on back-order

forgot to check back in on this. it ain't happened but a handful of times recently... but on a t-giving road trip this year, i noticed it happen a couple times while i was driving, and the engine temp showed full cold (having been on the road for hours & immediately prior showing right in the...

along these lines: i'd also started wondering what an "H3 Suburban" would be like... as in making a 3-row SUV out of an H3T.

shoot - i didn't think nobody still had a LT header for these. every time i'd looked for one, everybody was out of stock. this colorado one fit right?

weird that i hadn't come across these discussions over the years. ours is approaching 160k and didn't used to burn but a quart of oil every 5000mi change interval... but ever since we moved up into the mountains last summer - where our road is at the top of a three mile 6% grade @ 4000ft...

weird. in the last couple years, i've got extended temps from AZ and TX on the last two vehicles we bought when both had title delays. sounds like MI has stupid rules.

but you push the hood open toward the windshield...

just ask the dealer for another temp plate.

dang!!! did you make it home alright?! :eek: that's where your transmission fluid drain plug's supposed to be!! okay - not really we've got the same on our 2009 - assuming it's so you can either put a tiny bore scope up there... or to give a place for the fluid to drip out (or...

somehow miraculously, our Sentry Safe key also works on our cross rails... just a thought.

reckon i shoulda mentioned last week's fun in this thread https://hummer4x4offroad.com/forum/threads/stuck-slave-cylinder.15125/#post-248628
