what kinda 351? windsor or cleveland?,,,i know ford part and motors work well with rx7 sence ford took them over,,,,i got a buddy who is building one,,,but he hasnt decided on powerplant yet,,he is thinking 390 or 351 cleveland,,,,i know with a stock 302 it has the same power to weight ratio of a 1965 ac cobra,,,very powerfull cars with a v8,, and the beauty of it,,you only gain about 200 pounds,,and the front springs can handle it:) and only thing you have to do,,is flip over the main support bar and buy the kit and it all fits up nicely
way cheaper than tring to get horse power out of a rotary motor or 4 banger,,,,he allready went threw that,,thats why he going to v8,,he has dumped too much money into them little rat motors to realize he wont be able to keep up with the big boys in the end,,v8 lots cheaper,,lots more power
