'93 3/4 ton van 6.2 NA and it got aprx 17.5 mpg heavily loaded and in combined city and hwy driving. It has 3.08 gears and 235x15 tires. That was with a 4L60 trans, new tranny will be a TH400 but I'm not worried about losing the od (I'm going to load it heavier then before).
How 'bout somemore progress pics ? The young dude that's reworking my 6.2 just finished a 6.2 into Blazer conversion , and it looks very cool. I'm sure your's will be even better.
Everything looks to be exactly the same (it's parked next to an '85 6.2 on another engine stand). I don't believe it haS EVER WORN A TURBO ( oops - CAP LOCK).
I don't have a mandrel pipe bender , but with the 2 1/4" pipe being mandrel bent curves and with a crossover it should flow plenty...
It just has a little bit of clean-up to do and sludgy waterjackets. I don't want to completely disassemble the whole engine - if so I should have just started with a bare block to rebuild and gone from there. Also this will help keep me within a budget that's affordable.
Maybe I've made it...
Guess I should tell that it's a 1990 engine, I do have to buy a gasket set (Ebay/Felpro 6.2 set $95 ??), and we have to clean the heads alittle (couple rusty intake vavle pockets, slightly crusty water jacket @ the block deck area).
Should a better valve job +/or some porting be considered ...
Well after toasting my 6.2 in the van and selling the 3500HD it's time to install the humvee 6.2 , but there's been a problem. There has been alittle water inside this military "take-out", and metal on top of 1 piston - but dented pistons on all of three pistons. The rest looks "fresh rebuilt"...
Well after letting it sit for at least a week & 1/2, my out of work mechanic/best friend finally deemed me important enough to get off his duff and spent 3 hrs removing & replacing #1. He then got #3 replaced ( he said it was the worst one - lack of space), and moved to the pass side to start...
The 6.2 NA vans use the same short injectors as the 6.5 turbo, haven't been into mine any further to tell anymore differances - except that only 1% of vans were diesel.
I have a question about reaching the #1 injector and will start a new topic to see if anyone has a tip ! ( #'s 5, 7, 6, & 8...
I still miss my K30 5/4 ton granny-low 4speed gasser , even tho' I have a great 3500HD to replace it ! It was the "SS427 Yenko camaro" of trucks.
I'll take it (delivered of course ).
Sorry to be picky, but I'm sure you meant to list the torque peak @ 2500 rpm and the hp peak @ 3500 rpm, ( I didn't want anyone misled that may not understand completely).
Impressive torque output :smile5:
I won't drive over 62 mph because of the drop in mileage @ the higher rpm's.
(10,200lbs empty, 4.63 gears ,2wd, and a barndoor size bulkhead).
My best is a city/hwy average of 15 mpg (55 to 60 mph hwy)
There is a new listing for one in Lebanon, OH. Not sure if I can find enough time to get it before it sells.
( this going to work thing just takes too much of my time :mad2: :smile5:)
Wish I could've found this one and the one in south central OH at the same time, would have probably worked out good for both of us.
Did the Indy fellow have another 6.2 ?
