Re: Collecting information for a 1967-1972 K20 Surburban 5.9 Build

A few tips from things Ive learned along the way...

Do not start mocking up motor mounts/ Trans crossmember until you have absolutely everything in place. Engine placement is a balance between #6 valve cover being too close to firewall, fan too close to radiator, intake manifold hitting master cylinder. The turbocharger gets very close to heater core and a downpipe is a very tight fit. Engine placement up and down is also a battle. Oil pan gets close to front differential if not positioned just right. It can definitely fit very nice just take your time and be sure everything is there.

Also keep your options open...
If running 4" exhaust it will be a very tight fit past the transfer case. A driver side drop transfer case and front differential would make this much easier. If a passenger side setup is a must keep this in mind during mock up.

Set goals and stick to them...
Initially I planed on a stock non Intercooled 1st gen motor with a stock turbo. These projects can take years to complete and that can lead to changing of plans and upgrades. Now I am doing a p7100 swap, intercooler, and s300 turbo. It would have been much easier to have these plans initially and build accordingly.

Lastly plan on a solid suspension. Off the shelf lift leafs will not do.

Hope this helps!
