assuming that the 351 you are planning on installing to an ea shape body, is a 351 Cleveland, your gonna have a lot of trouble and an empty wallet... clevelands are too wide for the later model fords, and all require strut tower mods. i have already had this quoted @ approx $8000 which is a waste when considering that the 351 windsor bolts straight in. but then with decent power upgrade you have to realise that the t5 (if manual) will never be able to handle the power, and that the Borg Warner 21 3 sp. auto will have an unhappy short life. Top loaders and C4's (or better) are the only substitute, and are also the best value for money, but then you will also have to modify the transmission tunnel. Once you have completed all this, then it comes down to a 9" diff, which will have to be fabricated to suit the coil over shocks instead of leaf spring.... if your lucky, you might be able to find one in the trading post for under $1200.00 but in my opinion i think the better alternative to spending $20 000+ on a V8 EA 4sp. falcon, i'd rather prefer a vl turbo commodore (just kidding), nah seriously, consider twin turbocharging a 4ltr 5sp. (tremac tko or 6sp tremac t56)... Zoom Magazine have already turbo chargerd a 4.0ltr and managed 450 engine bhp on 10psi of boost.. also you have decent economy, with adjustable boost pressure (low boost for cruising and high boost 18-20psi for racing) and this would be a fraction of the cost of running and building a V8.
sorry if this sounds dis hearting but it is reality, maybe you should rethink this, like i have
