    Baad,
    did Auto Zone test your old starter or just sell you a new one? The shim is to get the correct gear fitment between the starter and flexplate/ flywheel and is not always needed.

    It could be 305, 350, just from looking at it in a motor bay you can,t tell them apart. You will have to run the numbers on the back left side as it sit's in the truck( driver side back) that will tell you if the block is a 305 or a 350 casting.

    The 305 came along around 1975. Most of the engine parts on the top are the same as the 350.

    Same:
    Air cleaner
    carb
    thermostat
    water neck
    intake manifold
    exhaust manifold
    valve covers
    distributor
    timing chain/ cover
    oil pan
    oil pump

    Different:
    305 heads/ max valve without mach work: 1.84"
    1.94" and up will hit block
    camshaft grind
    piston diameter
    rod thickness
    crankshaft
    block
    bore diameter
    flexplate/ flywheel
    starter bolt pattern
    harmonic balancer

    few people tell me look at the timing gear and see where it at because i cant find the numbers on it :confused: they are in different place the 1 on my 74 i have to look throw the water pump the 1 on the 73 is in view of the drive side fist 1 is 73 and i know i need a water pump :p the second 1 is my 74 it hard to see but i could not get a good zoom pic bit it on the back side of pump

    funny thing is when i bought this truck guy said it was a 327 but i know better i hope and far as i know 327 parts r different but i guess that what i get 4 buying with out look at it first

    The most accurate place to find engine size is behind the drivers head, on the block, where the transmission bolts up.

    The number on the back of my block is 14094766, looking at the following link, it's a 305, made from 88-94. The engine is suppose to be 1986. But someone else has been into this engine before me. May not be the original engine to the truck.

    http://www.73-87.com/chevy_ids/sbcid2.htm

    Another location would be on the front passenger side of the block deck. This location has more info, like engine serial #, vehicle engine went into and assembly plant.

    305 cylinder heads also are in lightened in the lower bolt holes thats an easy way to tell if you have a 305 or 350 since 350s didnt have lightened cyl heads

    Make sure the starter and block are free from paint and grime where the starter bolts up. There can be nothing breaking the ground. Make sure your engine has a ground between the engine and the firewall and the ground from the battery to the engine is clean also. If the starter from the vette works and your doesn't work very well, take it back and exchange it.

    Make sure good ground from the frame to the body too. Check wire make sure it's clean where it hooks up.
    VERY GOOD WORDS.
    [/QUOTE]If the starter from the vette works and your doesn't work very well, take it back and exchange it. [/QUOTE] This might be a good idea see it it was a bad starter.

    A Lot Of the Rebuilt Starters Have the Old Used Starter Heads on Them ( Aluminum on Most ) Sometimes the Bolt Holes Are Wollered out a Bit. Allways Buy new Starter Bolts When Installing a Rebuilt .

    It Will Make It fit Much Better Because the Old Bolts Most Likelly Have The Swedges Wore off of Them. I Have NEVER Used a Shim on Any Chevy Small Block to Correct a Problem. Only On the Other GM models or Big Blocks .

    The Other Posability is That Your Flywheel Might Have been Replaced with a Aftermaket Flywheel instead of GM. & That can Caues the Same Problem. But allmost Imposable to tell the Difference Without Taking it out. I Doubt this Helps Any . Just What I,ve found out & I,ve installed 100,s of chevy starters . Found Its Best to Buy Delco Starters NEW with new bolts & GM Flywheel Plates . Best of Luck . Bob

    Baad,
    you have too many wrong things going on here, somethings don't sound right.

    The vette starter worked, started and shut off fine. (right)
    The new starters are dragging and now you have to wire in a kill switch??
    Put the vette starter back on and see what happens.

    Are you trying to put a 305 starter on a 350 or vise versa. The starter shouldn't kick side ways when attempting to engage it. The wire that goes to the (S) switch post on the solenoid should be purple.

    tried the vett starter still no kill on the ignition just start buddy put a brace on the back of the starter to keep it from shifting an that is how we got it to work right he owns a 1970 and that how the shop fix his starter prob

    btw lol not wired kill switch just messing up my breaks high rpm then break hard kill any old chevy in a pinch
