First off I'd like to say hello I'm a new member. After reading just a couple forums it was a easy decision for me to make. Yeah fellas like the post reads I'm dropping a 1968 430 into my 1966 Chevy C10. I mean why not right? The truck needed a power plant and I love out of the norm things that turns heads and in this case my rear wheels too! I got a hell of a deal on the 430 with the stock TH400 bolted to it. I'm mainly curious if anyone's done a similar engine swap that has any advice for me or things I need to look out for or change? Any advice would be highly appreciated. Another thing I've read into is that these engines came stock with 10.25:1 compression ratio? That doesn't sound very street friendly on pump gas. Are there certain mods or different 400 or 455 heads I can swap on this thing to make it less likely to detonate? Any advice would be highly appreciated. Oh by the way I'm a regular working class guy who has kids so TA performance is out of the question I wouldn't even feel right spending that kind of money for parts on a hobby. Thanks again!
