[@andyharman3022]

Richard's tuned in to a very overlooked engine that never had its day in the sun. GM sort of killed it off when they offered the 5.3 V8 in the Trailblazer. The 5.3 had the same peak power, but more torque, got better fuel economy, and was cheaper to produce. Then people wouldn't go for the 4.2 I-6 anymore. It did have some weird features, such as the VVT on the exhaust side only, which was used to do internal EGR instead of broadening the torque curve. The early engines up to 2005 had a really small exhaust port, probably to force higher backpressure on the engine to enhance the internal EGR effect. Maybe GM went away from that in the 2006 refresh, when the head got a bigger exhaust port, and about 15 more HP. I bought one of the early engines out of a junkyard in Michigan to study, hoping to make a V12 shortblock for people to build DIY V12 engines. I designed the crankshaft, and didn't see any major shortcomings in it. I also figured out a cam drive layout for it. The guy that ported the heads on my GMC V6 was a drag racer in the Kalamazoo, MI area, and had built a 4.2 Atlas destroked to 3.8L, and went 7.80 at ~176 mph at Martin Dragway in a dragster. He said it ran about 10,000 rpm. He built a carbureted manifold for it.

I got an 02 trailblazer with this motor recently. It's been running rough. Starts and idles fine at first, but when it gets warm the rpms start dropping and fluctuation. Until it starts lopeing like a diesel and stallsthe past. Sounds andnfeels fine. Oil pressure is good, fresh oil change done just a few days ago. New vvt, and cps. It seems to have three original coil packs and three replacement ones. I havent checked the plugs yet. I cleaned the throttle body. There was some oil residue in the black intake that has 4200 on it. Brake abs light is coming on too. It's got 220k. I don't know what work was done to it prior. It seemed kind of well taken care of. The valve cover seemed to have been replaced with the last few years, no leaks. No drips. There is some vapors coming out of the oil filler cap an or oil dipstick tube. Does that sound like rings? I drove it about 2 hours to get it to my place. But I never had a gasoline motor before. I am kinda lost. Always had diesel in the past.

Excellent work again here Mr H as I've never heard of this mill and have been trying to decide V8 vs inline for a 49 chev PU in my deteriorating fleet. I was kickin around BMW or Jag maybe as the old 235's do not have any appeal to me but this just became a no brainer. Gotta do some homework now but I'm assuming somewhat avail and with all alum, really sounds like a resto mod motor you dont see every day. You can bet I'll be tuned in to see how this goes and many thanks for the other guys info RE caddies and buicks.

[@butcherbaker4258]

I have had one of these motors in my storage for about a year and for the long few of me I couldn't figure out what I should put it in I am going to put it on a motor stand tear it apart and see what condition everything is in.

[@rajunrick8410]

[@redlight3932]

[@richardholdener1727]

I'm easily excited

[@yusufkuntoro3141]

Rotary motor dyno test will be interesting

[@iliketacos2763]

Cool change for a video , these should do well making power . On a side note Barramundi on the grill with a couple of cold beers is great too .

[@livingintheLight.]

Can't wait to see you turbo this one out and put it on the dyno

[@young11984]

Nivlac57 did one in a fairmont, pretty cool seeing how he manipulated the VVT. Richard you helped him with some of the tuning if i remember correctly, wish the converter wouldnt have been so loose though

[@richardholdener1727]

i ASKED QUESTIONS-HE DIDN'T GET HELP FROM ME

[@anomamos9095]

Good turbo headers are more about consistent power than high numbers. A properly designed header will ensure that no one cylinder gets over heated from being too restricted. Too much restriction in the exhaust system causes power loss and slow spooling and high egt.

Get after it Richie!! Looking forward to the dyno testing. 👍
