Re: Mike's 60 Suburban build
thanks for the info, I have one that is getting a bbc/auto transplant, and was thinking that it would be cheaper if I could make the big 73-87 rad fit in there.
do you think with this rad mod that I would have space for 1 battery if I cut a spot for it in the rh inner fender well? |

It is cheaper as long as you don't mind welding and grinding. I spent more time on the inner fenders and radiator support than the rest of the engine conversion. |

Installed the rear dome light and wired both dome lights up. The suburbans did not come with a rear dome light, but I thought it would be a good add to have one in the rear. It is a stock dome light mount from a 60-66 cab.
I should get my engine back from the machine shop next week. So I've just been doing a few small things like this until then. |

Just received my injection pump and injectors back from being rebuilt by American Diesel Service. They have very quick service. I hope to pick up my short block and heads tomorrow from the machine shop.

Re: Mike's 60 Suburban build
now i understand its fuel injected ..i was blinded lol

When starting this project I wanted to get more than the typical 13ish MPG that I knew that I could build with a SBC. I wanted a burb that I wouldn't not drive because MPG sucked. I needed the power similar to a SBC, but am old enought to know I don't need a truck that can pull a track hoe through Colorado (or think I can). I read into low cubic inch SBC with turbo's and EFI and then looked at turbo 4 cyl diesels (4btswap.com) in either cummins or isuzu. I finally settled on the 6.2 with a Banks turbo with a 89 or newer block and 1 dot Riccardo combustion chambers and a 700r4. The 6.2 was GMs answer to the 70's oil price problem. They made a fuel efficient diesel starting in 82. The sticker highway MPG was 23 MPG for a 1/2 ton truck. It got a bad rap because the early blocks were prone to crack at the main bearing web. GM reinforced that starting in 89. It also is often compared to other diesels which are built for power like the Cummins. The 6.2 was never ment to tow a 8,000 lbs motor home. Not a fair comparison. Just like the Cummins was never ment to get 23 MPG sticker. It was designed to compete with the small block chevy and nearly double the MPG of a small block chevy. GM dealers started offering Banks Turbo's installed on the 6.2 as a dealer option and GM even adopted the Banks in 93 (I think) for factory trucks. My research for a high MPG engine that could move this burb well and tow 4 to 5,000 lbs occasionally is why I chose this engine. I know my burb is heavier than the 1/2 ton truck and probably has poorer aerodynamics, but my goal is to still get MPG in the low 20's. |

Thanks for leading me over here for the diesel install. I'd go this way if I could find a 5spd stick tranny for this motor. I just don't know of any. Does anyone? |

Assymbled the engine, painted it, and now it's back in the burb. Should have the rest of it done this week.

Re: Mike's 60 Suburban build
looks good ..have you fired it up yet?

Radiator and fans are mounted. Started on the oil cooler hoses. It's the first time I've used real braided hose. Aeroquip is the product. The ends are a bolt together reusable compression fit. High quality stuff.

Re: Mike's 60 Suburban build
i cant wait untill it is fired up could you do a vidieo!! so we could hear it!!??
by the way nice job on the build!! |

Re: Mike's 60 Suburban build
i am not sure how to load vidieos i think you have to post them on youtube then link themto here but i would love to hear that motor when it gets running i think it will be awsome!

Re: Mike's 60 Suburban build
The truck is now running! I have a big list of thing to fix, but we drove it about 150 miles this weekend to start breaking it in. I'm trying a youtube video below. My only worry is that the hot idle oil pressure is at 11 PSI. I expected it to be higher. It's at 38 PSI at 55 MPH. It drives great, quieter and much more power than my 62 p/u with a 400 small block.
|
Re: Mike's 60 Suburban build
I stopped in at the machine shop that did my short block and asked about the oil pressure. He said that my bearing tolerances were within limits, but at the loose side of the limits. That's why my oil pressure is down to 11 PSI at hot idle. He said that it will be fine at that pressure but if I wanted to do anything, I could add Lucas oil additive, or a high volume oil pump. Both of those would increase the oil pressure.

Re: Mike's 60 Suburban build
how loud is it in the cab when its running
|
Re: Mike's 60 Suburban build
It's quieter in the cab than my 62 p/u with a small block 400. I think it also quieter than the old 6cyl with turbo mufflers that came out of the suburban. Right now I don't even have a firewall pad. I'll add the firewall pad and something under the rubber floor mat in the future. I do have a dB meter that I could take some readings on to have a real comparison between a few vehicles. You can definitely have a conversation with the passenger. It seems like the diesels avoid some of the noise due to the lower rpm that they run.

Re: Mike's 60 Suburban build
Ordered some 3.73 ring and pinion gears. Need to change the existing 4.11s. A note came with the US Gears that said they are noisy. Didn't know that when I ordered them. I'll return those gears and either get OEM or Yukon gears, whichever is quieter. If I can find that out. I plan on doing my first reared in a few weeks.
I just got my B&M torque convertor lockup working. I had to replace the brake light switch with a Honda switch that had 4 connections, a normally open and a normally closed. One was needed for the brake light circuit (NO) and the other was needed to disengage the lockup (NC). Works great now, crappy instructions. Posted via Mobile Device |

Removed the cover on my 14 bolt rear differential. Can anyone tell me if this is a posi or an open carrier? From what I can tell, they both look similar on the 14 bolt. It's not obvious like other rear ends.
|
Re: Mike's 60 Suburban build
My carrier turned out to be an open one. I ordered an Eaton posi, 3.73 ring and pinion, and bearing kit all from thegearshop.net. Returned the noisy gears. Been driving it a lot lately and really like it. Can't wait to get the rear end changed to the 3.73 for some highway driving.
I need to do something with the front leaf springs. They are the stock 2 leaf and bent below flat about an inch. I did add about 200 pounds to the front with this engine. I found some 1400 lb springs (200 over stock) that show a 1 1/8" arch. Does that mean my front end will be 2 1/8" taller than it is now? The truck is 2 1/2 lower in the front than the rear currently. |

I installed the magnetic sensor for the tach. Since this is a diesel, they don't have a easy tachometer signal. This one will operate off the flexplate teeth. I had a aluminum block welded to the flexplate cover to allow enough thickness to thread for the sensor. Still need to finish the wiring and adjust the tech. I have an opitcal tach that will be used to adjust the dash tach for accuracy. The optical tach is a cheap one from Harbor Freight. You stick a reflective sticker on anything that spins (I used the balancer) and it shows the rpm.
The aluminum block is something I ground from an old aluminum electrical lug. I took it to a local welder since I can't weld aluminum. |
