    6.0l conversion in my 69 chevell

    i have a few questions for those that have done these conversions. im gonna be putting a 6.0l in my 69 chevelle with a turbo 350. im wondering will the turbo 350 bolt right up?
    can i use the same converter?
    flywheel?

    Im gonna put the victor jr carb conversion kit with timing module. will i need anything else to make that set up work?
    is there a conversion kit for engine mounts for a chevelle or wil i have to fab them?
    and is there a company that build headers or will i also have to build them?
    im new to this conversion stuff and want to make sure i cover all the parts part of it before i tear my car apart.
    1999 silverado ecsb 5.3L, gibson exhaust, gutted cats, cai intake, vette servo, TB converter, and hp tuned by me. now need ls6 cam and springs.

    1995 1500 rcsb got a 12 bolt rear end, PLAN (6.0L swap with 4L80E. fuel cell, cam, valve springs, rod bolts and spray.)

    there are adapter plates already made for the swap. You'll most likely need the ones with the 1" backset. Check out Hooker for swap headers, they're always introducing new conversion headers. Also be sure to check out Schoenfeld, site sponsor to see what they have available. As for the flywheel, you can get a custom converter made to bolt directly to the Gen3 flex plate, get a spacer and flat flexplate from an early 6L, use a converter extension such as the one available from Hughes transmission. The TH350 will bolt right up, you will have to drill and tap one hole in the block if you want all them to bolt on, not really necessary but it will make you feel better about it being secure.

    TCI makes an adapter flex plate and I think it runs about 180. As far as drilling the extra hole goes I had heard not to do it because it's fairly shallow and could go into the back cylinder pretty easily. Just what I heard. We bolted an LS2 to a th400 in a rock crawler without that extra bolt and it's hangin in just fine, even jumpin it and high speed desert runs at the hammers. Just my 2 cents
