it seams that i am acquiring what i think is a 67 cutty and chances are it will have the 330 so anyways just got to wonderin anyone runnin a 330? weather a olds or hot rod don't matter. its an engine you don't hear about despite that they make pretty darn good hp!
Most of the components are shared with the later 350 Olds. The 330 is unique in having a different(and if I remember correctly,more advantageous) lifter angle than the 350. Good stock and aftermarket parts available for them,they came with steel cranks(on the 10.25 cr models) and forged pistons(again,on the higher compression models;the two barrel version came with 9.0:1 cr and I think cast crank and pistons,I think). I had a '65 Cutl*** with one;had to run premium grade gas,but what a fun car. The Powerglide trans was a drag;a Turbo 350 trans would have been a good upgrade had I kept it. In a light car,that would be a fun mill for cheap thrills. And,different.
I had several when I was young. these were tough engines! I beat the hell out of them! If that '67 engine is a 320 horse you have a great one! 10.25 CR steel crank, heads flow good with a little touch up on the exaust side where there is a bump for california emissions. **** miller says the 4 bl intake flows as good as any after market, on the street. the cam would be a "toro" cam, out of the toronado. if your going to change out the cam I'll buy it! the crank shaft isn't drilled for the pilot bushing if it was an automatic. you can buy adapters now. (would of been nice when i was a kid, used to drill them out!) the 250 horse engine has a steel crank also! the only difference is the harmonic balancer. the push rods are shorter in a 250 HP engine! becarefull if you change cams it'll clatter like a *****!!! If it is a standard shift, i'd buy the flywheel from you! HARD to find!! I just found a 320 horse with 58'000 miles and a 250 horse witm 30'000 miles, they both run! I would buy another............. that "power glide" isn't... its an olds trans! it is 2 speeds, but has the switch pitch torque converter. thats 2 different stall speeds!
If you mean Cutl*** then yes I've run a bunch of them, never had a cutty . Good lil motors , run strong stock . Anything that fits the 350 or 403 will fit .THe only thing to watch is the cam, they used differant lifter bank angles in 64-67 on Olds , no problem to get just need to figure it out efore you order. 67 should be common 39* bank with .842 llifter , common 68 up stuff so cams can be had cheap. you can bore the block to std 350 pistons if you wanted
What else do you want to know? Others have already told you that this motor is virtually the same as an Olds 350 with the exception of the bore. The crank on the 330s is forged vs. cast nodular for the later motors. 1964 motors use a unique water pump and accessory bracket set due to the driver's side inlet vs. p***enger side on later motors. The 1964-67 crank flange bolt pattern is different than on the 1968-1990 motors, so the flywheel/flexplate is unique to those years. Others have talked about the lifter bank angle and the different lifter diameters (0.921" vs. 0.842" for most Olds motors). 1964 330s also have one-year-only heads with rocker shafts. All 65-90 Olds motors use bolt-on rockers with bridges to keep them aligned. Bearings, timing sets, distributors, intake manifolds, headers, valve covers, fuel pumps all interchange with those on other small block Olds motors, and except for the bearings, headers, and intakes, they interchange with those on big block Olds motors as well.
