Going from a 327 to a 350

[ian75c10]

I have a 1967 327 from a Camaro ( punched out to a 331 ) in my 75 c10. I have a 700r4 and 4.10 gears in the rear. Nice headers and a mild comp cam. I have been thinking about upgrading to a 350 or even bigger engine as I have no real good low end torq. My truck needs torq. So would I just be shopping for a new 350 block? what all cn I use from my 327. I have a good weian steal intake and expensive headman headers. I have a new 1406 edelbrack carb. i'm pretty sure I can use all those on the upgrade. I just want to make a check list of things to find to purchase or order from summit. Can you guys help me out with some pointers? I'l love to see some links to summit or jegs from you guys on good blocks. thanks fellas.

Intake and headers should swap just fine. Whether you get a new 350 or not depends on your budget and engine building skills. Heads from the 327 should fit but depending on which ones they are, they may not be the best for the 350 engine. If hoy need torque, may want to look into a 383 stroker kit for the 350. Or you can just sell all the small block parts and put a 454 in there. Torque problem solved.(-:

Thanks choptop, I like the idea of the 383. My c10 is a daily driver so the 454 seems a bit much. I am tempted to look for an ls engine I could afford but I am not sure how it will end up working with my classic co truck tags. I dont want to loose those.

I would say ls swap or 383, in that order. Efi and computer controlled overdrive will get the best mileage and longevity. Just don't overcam whatever you decide to run if you want torque.

     If you are in a area that goes by engine year, I would not switch and loose the classic co truck tags.

The 327 you have is worth considerably more than any 350. If it truly came from a 67 it will be a small journal crankshaft and is highly sought after by the #'s matching collector type barret jackson snob crowd. These things came in all kinds of muscle from 62-69 and they will pay good money for one if in need, and some would be willing to trade a lot more power in your direction just to have their #s match. If by chance its a large journal 327 then all you need to do is buy a new crank and rods. The 327 and 350 are both 4" bore motors and there's a .250" stroke difference between them.

      Sell the 327 and buy yourself a 350 and have money left over for some other mod.

Thats kinda what i was getting at bake. Its a good enough piece that someone will pay well for it and then you could do as you please with building or buying something more suitable.

Here in CO I have to register my truck every 5 years for the classic tags. Would it be feasible to have a small inline 6 engine laying around that I can throw in just before inspection every 5 years then throw the LS back in right after? What are some other tricks / loopholes? I am really leaning towards selling the whole engine and popping in a later used LS.

It can be done. I would sell the 327, then find a beater 305 to throw in it for inspections. A nice running 6.0/4l80e combo is hard to beat. Even more so when you slap an 80mm turbo on it.
