Just wondering if anybody has ever put in or has any opinions about putting a very well built, new 500hp 455 into a 75 Delta Royale w455.I know to keep the orig motor and it also would be nice having a potential replacement if something breaks on me. 500hp is twice what they put out stock, would the rest of car hold up to it? It would come from a lifelong trusted classic car expert and at very good price as well. Alright that's all thanks and fire away!!

 

The trans and rear end will handle 500 hp with no issues. Make sure the u joints and brakes are all up to spec. Good luck.

 

Yeah, I've got an opinion: The car would end up with about the power level it needs to get out of its own way.

If the engine is a true 500hp, you'd probably get 0-60 in about 6 seconds, which is the same as some Acuras these days, but only IF you could keep the rear wheels from spinning.

I actually just did a cam for a guy in CT that is putting a very stout 455 in a '74 Delta.

Why not? It sure would turn some heads!!

 

Unless it's a Royale with cheese.

Oh come on! You knew it was coming!

 

Didn't ask you don't know what you say fella
