Nice motor....but that didnt really prove anything. Plus modding that motor with hardly any aftermarket parts for it would make less sense and cost more than just keeping the 7m or j motor in in the first place. The reason they wana use an american v8 is for the performance/cost ratio and availability or engines and parts, Basically unlimited. Plus having a v8 is just cool (sound effects, braggins rights)

It is possible.

very possible. i second everything this guy says. i was looking to do the same thing with the 427 except i was going to spend another 2000 dollars and put twin turbos on it u can get 744 hp @ 5000 rpms and 798 ftlb @ 4500. that was my plan until i found a 302 DEstroker i can get 821 hp @ 8500 rpms and 714 ftlb @ 7500 rpms. (i have a engine dyno simulation program) less stress on the supra trans and rearend i have so i shouldnt shell it out to quickly.

My idea is, if you have an american block, put it in an american car. And if you wanted a big V8 in the first place, why did you buy the supra? Think about it, then realize how stupid this is. Oh and by the way, one thing no one mentioned, the amount of piston power from the V8 making it move from side to side, would probally rip the chassis in peices, so you'd need either some NICE chassis mounts, or just say fuck it.

It doesnt matter if you think its stupid, so dont rag on him for it. Its his car. The reason he wanted to put a v8 in is cause he has the supra already, And wants a bigger motor. Its that simple. And the chassis is perfectly capable of handling the extra rotational force. If that is too much for the car, It would have broken long ago with the 7m motor. That is probably the last thing i would worry about breaking. Maybe the rear end, half shafts, Rear suspension, Things like that.
