Hey all. I figured I would start my build thread to document the process, two days ago I picked up a 300 Inline 6 from a buddy for $200 (Runs perfectly and has 77k on it). The plan for it is a full rebuild and to add some boost. Parts and things being done include but are not limited to:
HD manifold
Complete gasket and seals kit
“Cu**ins Beige” Paintjob
Custom Turbo piping
HX35 Turbo
Holley Sniper EFI
Offenhauser “C series” intake
Custom turbo cam from crower
Crower pushrods
Crower Roller Rockers
Flywheel
Dual disc clutch
New fan
High volume oil pump
Arp everything
It will be backed by a ZF5/Atlas transfer case and be going into a Scout II. :beer:

(All the original parts that I don’t use or change out will be posted for sale in the correct forum)

Casting numbers “LTE-3015-AA”

Not sure on the year as the casting number is way to vague, will update once I pull the valve cover off tomorrow and see the head date. As far as rockers go I’m going with the Crower Enduro Aluminum Stud Mount Roller Rocker Arms. 72828-12 is the part number.
 
Thanks for posting the engine pictures.
Looks like it will be a good core

You obviously have done your homework. The parts list looks good. Nice job!
In stead of flex plate I think you meant to say flywheel.

What are the plans for head work?

How much boost?

No problem. I’ll be posting pictures throughout, not quite sure how much head work will be done yet. As far as boost I’m hoping for 15-20 psi. I want to keep it as low in the rpm range as possible and I will sacrifice some psi for that if need be.
 
Be sure to ziplock bag and label every set of bolts.
Will make it much easier to assemble later.

Good tip and one I have used for every engine I’ve built! Otherwise I’ll never find them again :roll:
 
If this is the Crower turbo cam you were thinking about using, it has low enough valve lift not to need an expensive roller rocker.
If you want roller rockers the Harland Sharp S4002 are $310 from Summit.
I'd rather see you put the money into pistons.

That’s around what I’ll go with cam wise. I’ll probably do roller rockers regardless as I’ve loved them in V8s, and I’ll 100% be swapping pistons to handle the boost better. Don’t feel like cracking some hypereutectic pistons so I’ll be going forged.
 
I like roller rockers also.
I was just thinking that the Harland Sharp S4002 roller rockers are $310 from Summit and are a lot cheaper than the Crower.
