i am looking at a 5.3 alloy block LS for my right hand drive 93 GMC C1500 extra cab
it is running a 350 and 4l60E,, engine has had poor service from new,, previous owners will hillbillys. vehicle is rust free and deserves a second life. steve in Australia.
I heard a lot of really bad things about ATK. I'm glad yours works but would you attribute that to maybe people not following breakin instructions?
Break-in period is pretty important. The other thing is, we know that there is always some bad workers at every company that are just there for the paycheck and slack off. There is always the possibility of getting a motor that was built by an employee that could care less.
Just curious how the engine has held up since the video?
Very nicely! No issues at all!
This the one from Jegs? I just ordered mine will be here tomorrow. ATK as well. Thanks for the video! This is what I wanted to hear lol
Yes, u can buy this from Jegs.
Hey. How did things go with the motor?
@@tevingay8030 it’s doing very good! It’s been installed since august of 2019, only has about 4500 miles on it though. Only issue is the oil pan started to seep, bolts just needed retorqued.
@@CollinZ71 okay great. How long did it take as far as delivery times go?
@@tevingay8030 I can’t remember exactly. The first one got dropped in shipping. I think it within two weeks I had it ready to drop in, the damaged one arrived within 3 days I think. I’m from Iowa, I think they shipped out of Ohio if I remember right.
This is just me but I would've went with an edelbrok intake and carb and go with hei distributor. To me it's less of a headache with injectors and what knot. But that's me
I agree, and that's my plan. I just had to get it going asap, becuz it was my daily driver for a while.
@@doggngarage4975 10 4, I've got a 79 Camaro I'm currently working on. Had a 305 in it as well. Thinking of going 355
Same body style my '81 Z28 was. Ended up trading it for an '84 Trans Am that I ended up building a hefty 350 for.
355 would be a nice powerplant for that Camaro
@@doggngarage4975 nice, I have a friend of mine that has a fully restored 81 trans am. And a cousin with a 69 charger that we are also in the middle of restoring. But its gonna take several years for it to be finished
That's awesome. Gotta keep the old American Muscle rollin!
I got a 95 Tahoe 350 TBI. What's required to go from stock to the ATK 350. Jegs says you need a chip burned.
I didnt do any chip burning. I had to swap the ECM, but that was because mine originally had a 305. If you originally had a 350, you should be fine to just drop in, time it, and go.
@@doggngarage4975 Ty! I appreciate your feedback.
any trouble valve adjust mitt i bought the same eng from summit racing parts ATK 5.7 I just did the cam run in but the valve train is nose ?
A little tick out the left exhaust bank, but never really pin pointed the cause. Doesn't seem to effect the performance after these years.
Don't know if you can help I replaced the ecm on my 87 350 tbi cause it was burned and the iac was open now the idle is really low and running rich no codes did the tune up plugs wires cap and rotor
The ecm was of a v6 could this be the problem?
Yea, you'll definitely want a 5.7L ecm
Thank you!!!
What kind of water pump are you using? I’m having some problems with mine overheating
Stock water pump replacement. Mine is off a '94 donor. The thermostat opening? I use a fail-safe thermostat.
@@doggngarage4975 what rotation is it?
Reverse rotation
Not to be confused with reverse flow. The water pump still sucks coolant up from bottom radiator hose, but the rotation of the actual pulley on the water pump is reverse since it runs off the back of the serpentine belt. So basically it spins the opposite direction of the engine rotation.
Will i need the same things you mentioned if I'm going from a v6?
Definitely. You may even need a little more, but these items would be a solid start.
@@doggngarage4975 thanks you brother.
I'm thinking of dropping an ATK 350 into my C3 Corvette to get it going for the time being, but I am afraid to pull the trigger on it due to some of the reviews I have seen of the company. How is yours holding up after 4 years?
I've heard mixed reviews. Seems like most companies are struggling with quality since covid. Mine is holding up great still!
That would make sense, most of the negative reviews I have seen are from the past couple of years. Thanks for the input
Is it a 2 bolt main?
4 bolt
How long did it take to swap?
A few days. Hit a few snags along the way, as usual.
What headers fit on the engine?
The main thing is to search for gmt400 ('88 - '98) headers. They will more than likely be compatible since a high majority of these trucks were made with small block engines. I ordered stainless steel headers off ebay. I've driven it for almost 2yrs, and they haven't cracked or anything. I did have to cut some of the alternator/power steering bracket and put in a small bolt spacer though since the bracket originally mounted to the stock manifold.
Dogg'n Garage 👍🏼. I’m doing the same swap this week. I still need to resource the parts I’ll need. Heading to the junk yard first thing in the morning. Which ecm will work, certain part number you prefer or does it matter since it’s out of another 350?
The ecm I got is a 6299... mine is a '92. Just tell them you need an ecm from a truck the same year as yours that had a 350
Dogg'n Garage is there any reason why my esc is not mounted on the same bracket? No where to be found.
That's strange. What year is it?
