    66 Skylark convertible 455 swap

    Hello, I am new to the site. I have had my Skylark for 2 yrs now and I was inches away from putting an LS-3 in it with a TKO 600. It currently has a 340 4bbl. While I would still like to go with the six speed, I am leaning more towards a 455. The members on this site have shown me the error in my ways. i just have a few questions that maybe someone could help me out with?

    1. The transmission in a 2 spd auto with " switch pitch" convertor. since i don't have the money to do the eng and trans all in the same year, with the 2 spd bolt up to the 455?

    2. Will a TKO 600 bolt up to a 455? Do they make an adapter plate? I am aware that I will have to make mods to the floor and i would also like to run a hydraulic throwout bearing, but i was wondering
    if there was anything else big that is was missing.

    3. I can find a lot of headers for a 68- 72 big block Buick, but not so much for 66-67. Any help?

    Thanks in advance for any input, comments or even pictures. :grin:

    Welcome to the site. 1. An ST300 will bolt-up to a 455. 2. Any BOP bell housing will connect a 455 to a TKO600. 3. 300/340 headers are few and pricey.
