@Rusty Nuts Thanks for answering the question boss man, and I didn't find anything to do with the 304 swap im new to the mechanical side of things and i dont know anything about Ford motors idk what a 410 is tbh grew up round Holden people thats why seeing a Ford motor in a 34 in some article wouldn't help me i didnt know the 410 was the same size as the 304.
And i dont wanna go with an ls because I love my Aussie built holden motors dont wanna use the ls its boring everyone puts em in everything they're everywhere and iv not seen a 304 in skyline before, im essentialy taking the motors out of both my cars and swapping them into each other, so rb25det powered vs ute and a aussie v8 powered r33.
