Big Daddy 0 Report post Posted April 11, 2015 I have a 6 cylinder 3 speed 1969 mustang convertible.that needs to have it's non original engine replaced. thinking of replacing the engine with a 302 (out of a 70 mustang), and keep the same transmission. what modifications need to be made (besides replacing the radiator, motor mounts etc). to make the replacement smooth Quote Share this post Link to post Share on other sites

stangs-R-me 120 Report post Posted April 16, 2015 Agree with everything that barnett said. Was it a 250 or a 200 six ?? 250 six came with 5-lug wheels and same brakes & suspension as 302, so all you would need is the V8 springs & maybe sway bar. If it had a 200, it came with 4-lug wheels, smaller brakes, and possibly suspension components which should all be up-graded to 5-lug. Doug Quote Share this post Link to post Share on other sites

Big Daddy 0 Report post Posted April 22, 2015 Thanks for all your feed back, it was very helpful, and now i have something to work with. I am developing a check list with estimated costs to see if it is worth the extra $$ to make the change. I was told by several people that if I made the change to a V8 the value of a mustang would increase 20% is this true or BS ? I will let you know what my plans are for my weekend mean machine. Thanks again Quote Share this post Link to post Share on other sites
