hey just bought myself a 67 cutlass hardtop 2 door with a 330 rocket and 2 speed tranny. anyone know of good places to score parts? i managed to get a holley intake on kijiji for 80 but i mean even a chrome waterneck ebay is 40 maybe im used to small block chevy parts bein so cheap but will 350 olds parts fit? say a cam etc? cant seem to find any places with performance goodies

captjim

Just curious, but in what way is a chrome waterneck a performance part?? That said, almost all small block Oldsmobile parts interchange, especially 350 parts on a 330. Intakes, headers, ignition, etc.

sorry to offend performance AND dress up

captjim

Just busin' your chops a little, not being serious.

When you look for a cam, be sure to indicate that the 330 is a 45* cam bank angle. All Olds engine, 68 and newer are 39* cam bank angle.

all in fun, so on the most part olds 350 performance parts and stock parts will all interchange on to my 330. because edelbrock holley comp cams etc all carry 350 olds stuff just no 330 any good websites out there ? thanx alot for your time guys

I have been told by my local olds racers a 330 can accept an overbore big enough to hold a standard sized 350 olds piston.

Can someone what a cam bank angle is and how they changed it from 45 to 39 degrees.

svnt442

You don't change the lifter bank angle.

Fun71

The bank angle is the angle of the lifter bores with respect to the camshaft. Early blocks had a 45º angle and later blocks had a 39º angle. The angle is part of the block manufacturing process, so it's just a different manufacturing design.

olds 307 and 403

I believe your 67 is supposed to have the new 39 degree cam bank angle but I would double check. I would also stay away from that chrome water neck. I had two and no matter what they would not seal and I believe they are more like $20 at Summit. Parts are more expensive but they were built better and more durable than the sbc, mid 70's version especially and something unique under the hood. Keep an eye on the for sale here and on Real Olds Power for parts, people are much nicer here though and take our advice. We even have guys who were with Olds in their racing days, actual GM employees who have really neat stories. One of the best upgrades for performance would be a mild built 2004R overdrive trans and gear swap, the best of both worlds.

Cheap and oldsmobile don't go together.

Cutlass Fan

So is camshaft higher in the block in the 45* bank angle to accomplish this? How is the angle measured.

Oldsmaniac

Yes this I also believe to be true and the 67 425 as well but always double check.

70cutty Cheap and olds totaly go together lol just depends how you go about . 12.60's and i have less than 7k in my whole drivetrain trans and diff included. There is guys running much slower with 6k into a whole engine.

70cutty

That's not cheap.

coppercutlass

Like I said it's relative. If the average engine runs 6k alone then 7k for the whole deal ain't bad. Considering my usage aswell

My trick to getting chrome water outlets to seal is to remove the chrome plating from the gasket surface. I start with 80 grit and work up to about 220. I've not had one leak since I started doing that many years ago.

IIRC, everything is in the same place. The lifters just have a different approach to the cam, requiring different cam grinds (and usually different cores! a 39deg core is very difficult to regrind to a 45deg and vice versa, just not enough meat there). Unfortunately I don't know the engineering reason for the change.

Stick a well-fitting dowel rod in the lifter bore sticking up towards the deck. Place a ruler vertically on the deck with the edge up against the dowel rod. If the dowel and ruler stay aligned with each other then it's a 45deg lifter bank. If they diverge, then it's a 39deg bank. The actual angle is measured from vertical to the pointing angle of the lifter bank.

Here you go:




And if you want even more information about it, see this thread.

Correct, which is why the same timing chain fits both block styles. Actually, the same one is used for all second generation Olds engines.

In simplest of terms- cam angle is the angle of the "V" in a V8 engine.

ELY442

X2, I use a cast iron type and it never leaked.

MDchanic

No.

The angle of the V is 90° in all of them.

oddball

A 90deg V8 is 90deg between the piston bank centerlines. There are narrower V engines. V6's tend to be 60deg, exotic engines can be more interesting. The lifter bank angle is just extra sauce thrown in. Lifter bank angles are all over the place in different designs, with some engines with really high cam locations having >50deg.

Thanks oddball and Eric. Apologies to the OP for a bit of a thread hijack.

Congratulations!!!
i just picked one up myself.

What did you pick up?
