I have finished rebuilding my 330. Just primed it the other night everything gets 50 psi of oil. Now power washing the engine bay before reinstalling the engine.

Congrats

Where did you get your 330 engine parts from? I want to rebuilt my 1964 Cutlass Convertible 330, I look at Supercarsunlimted and Egge engine parts. Can you tell me the difference between the early and late 330 engine, are the heads the difference? Any information would be most helpful! Thanks, Jim

Honestly I am not that knowledgeable on these engines. I researched on this website. I used 7a heads with egge pistons. And if I were to do it over again I would keep the forged crank out of this block and used a 350 because of piston availability.

Differences are mostly in the block castings. Early block castings are the 45 degree blocks, late are, most of the time, 39 degree blocks. Other than that, pistons, rods, crankshafts, etc are the same. The differences in the heads will be in the rockers assembly. Try to find a set of #4 heads for your build.

Thanks to both responses! Jim

I think the only internal engine parts that are different between the 330 and any other SBO are the pistons, so you should be able to purchase a rebuild kit (minus pistons) from just about anywhere. You may be able to use standard 350 pistons but need to ensure there is enough material in the block to support the overbore. Otherwise, you can buy 330 specific pistons from Egge then get the rest of the rebuild kit from wherever.

There are 2 different pistons, low comp and hi for the 330. There are 2 different intake gaskets, a 4 piece for the mounted tray in the lifter galley and the turkey tray for without. Yours most likely is the first.

The 330 pistons are expensive make sure you get the higher compression pistons otherwise you will end up decking lots like I had to.

Thanks to all for your quick responses! My engine is hi compression.

Also be aware that the Egge pistons are aftermarket cast and from what I have found are short on compression height, just like other aftermarket cast pistons. Keep this in mind as the engine's compression ratio will be lower than expected unless machine work is done to compensate as 330jetstar said.

Engine is back in the car. As soon as I get all the brackets pulleys and hoses on. Rewire a couple things I will have it fired up.

Cool, then you get the experience of Dr. Frankenstein... "Now I know what it feels like to be God"

Ok here's one for ya. Can anyone give me a part number or supplier for upper and lower rad hoses on a 64 Jetstar 330.

330jetstar

I found the lower on fusick. Still no upper. Getting the engine back up and running is a slow go.

Ok now I have done the can break in and finally started my engine after the rebuild. One issue in having is timing. I bought a new harmonic balancer and the timing marks were on the opposite side of the original which was passenger now driver. So I purchased the driver side timing marker however now with the engine in the car and the water pump hoses on I can't time it at all because I can't see the marker. Now can I simply mirror the timing markers on the balancer scribe deep enough lines and remount my original timing marker. What a mess. I ordered the balancer from summit using 1964 year when ordering.

Also I tried to upload a video to site of my cam break in but that's not working either.
