Hi All,
New on here but wanted to get some good quality advice on 'what path to go down' regarding dropping a new engine into my old 1992 GMC K2500. Its been in the family since new and has sentimental value. The truck has 410kms on the body (SLE, Extd cab, long box), about 275kms+ on the current engine (stock 5.7L/350 TBI) and about 235km+ on the trans (not sure what type/model).
I'd say the engine is on its last legs, i.e. its knocking (very bad and has been for years), exhaust leaks all over, lost compression, oil leaks everywhere and occasionally overheats under loads etc etc. Transmission seems what you would expect for its age but its not great. To note; we use this truck as our camper rig, we have 9.5ft Kodiak camper that we use on a regular basis, weighs around 3000lbs fully loaded, and usually we travel up to 500-1000kms per trip which is a mixture of highway driving (mountain passes) and forestry service roads (rough). Would like to travel further but scared of breaking down too far from home! haha.
Given that this truck will be a full time camper rig and the occasional work-horse around town vehicle, I would like to have a strong and reliable setup that has excellent mid-range torque and responsiveness under load (I would like to accelerate up hills fully loaded no problem). NOT looking for top end power or a hot rod 4x4 machine.
Questions:
- What crate engine would you recommend? is a standard 350 TBI replacement going to suffice? Or, will a new 350 TBI with modifications meet the above specs? Or, is something like a HT383 a better option?
- I'd say all of the engine components are well aged and will need replacing also, whats needed with a new crate engine replacement? I imagine its a long list but I've got not idea about this.
I am not shy of replacing radiators, water/fuel pumps, exhaust/headers, or anything else that is needed.
- Would I be wise to do a full powertrain replacement at the same time? (I think yes...). Transmission recommendations?
Lets get the ball rolling with that for now. As mentioned, I know its an old truck, but I love it and dropping a brand new engine/trans and what ever else in her is still a lot cheaper than a truck with 100kms+ on it. I would like to keep the overall costs around $10-15K, realize this is one hell of a project but its on my life's wish list to do!
Appreciate the help! Cheers!
