what do you mean as far as parts...list em up! years?
its a different engine than the 396, which has a shorter deck.

well, cap n rotor, valve cover gaskets, plugs n high temp wires, carb gasket, oil filter, fuel filter, air filter.

take some pics...those parts should not differ from standard BB stuff.

The 366 is a truck (esp. dump trucks and school buses) specific engine produced from mid 60's till mid 90's.

It is a big block - actually an underbored, high-decked 427. It has 4 piston rings (reason for the increase block height).

Considered by many to be virtually indestrucable.


The parts you are looking for should be the same as what is used a stock 427.

ight, ima start on one tonight, this one im replacing the carb with and edelbrock and tune up.

 

[Jims86]

Just found out that you should be able to match up with 454 as far as gaskets. I dout GM produced a specific distributor for it. so, parts for tune up should be a piece o cake.

 

[Kapdin]

huh, 427. maybe one should happen to blow up and be pulled out

What year are they......ouch on the edelbrock!

 

[Kapdin]

um, the oldest is like gmc 68, then gmc 75, and then chevy 79. and the stock carb is so far shot. and would cost way more than the new carb.

Quadrajets?
I understand if you already have the edelbrock carb. They just farm trucks, or do they go out on the road?

 

[Kapdin]

well from the farm to the feilds to the elevators so yea road, why whats wrong with thos? i kow the stock ones have a gov. on them so they don't over rev and this doesn't but grandpa alrdy bought it.

yeah....the stock carbs are better economy, and reliability wise. Edelbrocks are smokey gas drinkers. Governer is a good idea with those engines.

All those parts are easy to find if you can get a parts guy to get off the damn computer and get the heavyduty books out. I loved getting parts for those trucks when i was working at Oreilly's. Its really easy to look them up since you know the years and all that.
