    You'll never know what you're missing if you never try a roller cam! How about a LVL3 roller grind?

    And the TA cam that is similar to the LVL3 would be the TA 212 IIRC.

    So the spare engine is not really a 68 engine. It has a 68 4 barrel intake, a 71 block and 72 heads. No Quadrajet, but a spread bore Holley instead. Someone’s Frankenstein motor, I guess. Plugs are not too bad. Exhaust manifolds came off pretty easily. More digging to come.

    Most everyones Buick engine is a Frankenstein of sorts:D
    Mines the original '71 block with '69 heads, SP3, AED 850, headers, roller cam, roller rockers, forged pistons, rods, etc.
    Have fun with it:cool:

    After a couple weeks away from the project, finished disassembly of the spare Buick 350. Everything looked pretty decent inside. What looked to me like normal wear on the bearings, some fairly heavy carbon build-up on the heads and piston tops, but that is all going to be replaced anyway. Everything Isaak and I took off is bagged and labeled in case we need any of it. Next step is taking the block to my machinist, which should happen later this week. Hopeful that everything checks out well.

    You should do some oiling upgrades on block, atleast the pickup passage and use a 76 and up 5/8 pickup tube from melling.#20is5.

    Isn't that 5/8" pickup available from TA performance? I was planning on making that upgrade, as well as enlarging the passages. Is there a thread here on the forum for 350 oil mods?

    On a side note, the spare 350 had a flexplate on it, not a flywheel, so any threads detailing that modification would be helpful as well, since I want to keep this car a manual.

    Appreciate all the good advice! I'll see if I can throw some pictures up here in the next few days.

    Any suggestions about which lifters to select? Johnson? Delphi?

    Nice! That's the way to go, no modifying or machining required.

    Delivered the block to the machinist week before last, and had a look at it today after coming out of the hot tank. Nice and clean! Cylinder walls look good and will probably need very little boring. It went into the shot peen cabinet today for scale and rust removal.
    The timing cover cleaned up pretty well and seems to have a lot less scoring and wear than I thought. Packed it up and shipped to TA for the full porting and oil pump treatment.
    I am a little concerned about some of the roughness on the inside of the cover, should I smooth it out with a fine die grinder? 539BD0CB-2C1B-473B-B858-D1D2329A7F13.jpeg 41DFE8BD-CB2F-4934-8A97-C2A12CB61216.jpeg 96D1009E-0ACB-4599-AB1C-16935B8C1C56.jpeg FCF4FE00-9814-4312-AA5C-5450928B8A48.jpeg 776E26AB-63DE-4D62-9178-6A1776820E60.jpeg 1E2DF5ED-3728-447A-A461-0F04B3205BB6.jpeg 40A1443F-4A79-4CC3-9DCA-420C62939497.jpeg 857EFC51-FFA3-4058-A38A-A25873FCD947.jpeg

    I ran the 310 for years, good cam, ran the 413 good cam also, switched to a roller now, the roller specs are milder on duration and overlap than the 413, but idles with more lope, but your comparing apples to oranges as far as valve events.
    I LOVE the roller cam:cool:

    I imagine the ta 310 roller cam your considering. The ta 310 flat tappet is ok. Straight pattern.
    There are better cams.

    Good idea to get your pan modified by Steve. His alum version I’m using is a work of art. But his stuck modified version is plenty nice.
