    The heads have no bearing on the cubic inches. The measurement you gave is the valve size....intake side I would think

    .030" over is roughly 6 cubes.

    Pretty sure '30 over' is a 355 when it comes to the LT1.

    I don't think .30" would be safe...but I don't know those motors that well. Just seems like a lot.

    Right

    .030 = 30 thousanths of an inch (Think about matchbook cover thickness)
    .30 = 3 hundredths of an inch (Think close to about 8mm)

    Most likely your block is bored over .060... that is as big as most will go.

    You could call it a 5.8 liter engine if you want, that way you'll start conversations about it. Back in the day, the Chevy 350 engine under the hood label was 5.7 label, and the Ford 351 engines had a 5.8 label. So, if your engine is .030" bored over, technically this gets you ~355 cubic inches which translated to about 5.86 liters. A Chrysler 360 is labeled as 5.9 liters.

    More fun engine liter trivia: Fords ohv 5.0 (302 cu in) is actually 4.949 liters, they should've called it a 4.9 engine. The Chevy ohv 5.0 (305) is bigger so it properly rounds out to 5.0. The Pontiac ohv 301 was correctly labeled as a 4.9. And this engine made a whopping 135 HP! 150 if in a 1980 non-turbo TA.

    i appreciate all of your responses!!!! i didnt get a chance to call summit or swing by the shop to get the details of the engine, im gonna try to get to it tomorrow before work. today i was putting in a new alternator and fixing a stripped pulley bolt. one problem that has me stumped is that the car wont wanna start after its been running for a bit, like the starter is hot and weak or somthing. its a new starter for a stock lt1 but the car has the bored out engine, cam and bigger heads so i was wondering if i need a stronger starter??
