330 questions
i am new to this site and hope to get some good information for my engine build.
this is where I am at with my 330.
Block .30 bore
line bored
901-16 Comp Cam
forged stick crank
honed pin ends and drilled holes to float
new Mondello 4057 Bore Pistons - Flat top
mondello rings
high output oil pump - mondellos

Continue
springs to match the cam
new exhaust and intake valves
steel retainers
surface heads
new hydraulic lifters
pioneer performance valve stem seals
valve guides
locs
VSI shims
SBI brinze guides
multi angle valve job
Edelbrock 7111 intake
dual exhaust
edelbrock 750 carb
whew. I have been working on engine for years. The question now is hopefully easy for many of you. Have I built something that will give me some additional horsepower?
2100 stall converter to 300TH
i am thinking of a single turbo option that is put out by TorqStorm.
Any my suggestions would be helpful - except ones to get a 455 etc.. I already have a ton in this build.
thanks

Flat top pistons will likely result in way, way too high compression for using a turbocharger. I think you'll have enough power as it is.
FYI, "901-16 Comp Cam" are valve springs, not a camshaft. What cam do you have?

Cam number
Sorry about cam mix up. I was looking at all the cardboard cutouts from the parts I purchased.
the cam is a Competition Cam Camshaft. I did ask the machinist to put a “mild hotter” cam. Can find that number right now.
How many HP you think I could have added?

Well, with no idea about the cam specs, how it's installed, or how/if the engine is tuned, you could be anywhere from actually losing horsepower to adding some.

Not Good
That would going in the wrong direction. I did go with the MSD complete ignition system. The only part of this build in question is the cam and the tuning.
it also had a balance from damper to flex plate.
as you can tell I am learning. I have been wrk on and building engines since I was a kid but never invested in a build like this one.

That cam is a bit larger than the factory cam, so you are headed in the right direction.

.433" lift, 252 advertised duration, 206ş duration @ .050" Lift
You could definitely go larger with the compression ratio those flat top pistons give, but it all depends upon what you are wanting from the engine. You keep mentioning forced induction so I get the feeling you want a LOT of power, but it seems as if you didn't build the engine to be compatible with forced induction.

Thought So
i was afraid that I did not build a good platform for a super HP car. I know that I have several thousand in engine and tranny.
i wonder if I can go back and make amends seeing I am pulling the engine apart now to put in new rings. There new but it did not have a good break in experience. This engine was built 9 years ago.
what I want is an engine that fits under the hood (lol) has a lot of HP but my wife and I can take it on day trips and car shows.
the car is a body off restoration of a 1966 Olds Cutlass. I am doing a clone 442 - down to the trunk trim (almost impossible to find) the correct placement of badging and interior.
the only way to tell to to see the 330 engine instead of a 400.

371
I do have a friend that is offering me a 371 with tri-power J2. Seems like there are a lot on sale though.
thanknyou for help as I sort through making the right move with my baby - the cars name is Marilyn - as in Monroe.

If you're taking the engine apart to install new rings, you could do a cam change as well to take advantage of the compression. Check with cutlassefi for cam recommendations - he'll probably be able to set you up with something that will make your 330 happy.

The bobweight is the balance weight for each rod throw. It consists of two Rod big ends, two sets of rod bearings, 1 piston, pin, rings and small end of the rod. The reciprocating weight cancels each other out to some degree. What did the card say for weight?

I am surprised anyone makes a higher stall for the ST300 2 speed. You could pick up a set of the 6cc dish version of that piston, would have to check weight for balancing. I assume 93 octane, anything else would be a pinging nightmare. With slightly less compression, a cam swap is still a good idea.

I agree Mark and a proper hone might not be bad since there was ring sealing issues. Those Mahle pistons are way lighter and have much thinner rings that should seat easier. I figure around 9.5 to 1 with the Mahle pistons. I use this calculator.

Cam will need to be something in the 220+@.050 range on a 114lsa with 10-14 degrees of stagger.

What Suggested
what modern engine would you suggest and a cam and pistons to go with.
I guess I will be building this engine and tranny based on complete input from this forum. It may start to get a bit crazy.
Are you thinking of an Ls motor? Chevy, Olds, Ford, Hemi... lets get this game started.

With the compression ratio you have, coupled with the stock iron heads, you’ll be detonation prone for sure if you’re not careful.

350 to 400
and 921 lifters. i purchased Edlebrock headas and sprinhs as well as a set of roller rockers. i also went wit a W30 from a speed shop. i am looking for 921 lifters. i only need 4. if anyone has some that would be great.
