Turbo 273 ?s

Close to 400hp imo with the 273. The 360 would be night and day! BIG issue in your 1st gen A-body is ROOM.
I wouldn't start on this until you are absolutely sure this is what you want! The car you have now will be nothing of the sort once turbo'd. Everything has to be changed. Fuel system, Ignition system(I see your BTM), exhaust system, oil system and so on. Once you think your done there are a thousand nickle and dime things that will bite you. Believe me, I know first hand. As much cash as I have spent my car could have had a 500"+ stroker and a complete new interior complimented with all new chrome/trim.

Once mine is running here shortly, I will know if it was all worth it!

After all my rambling and you still want to do this, READ everything you can and keep reading! Carburation will be your biggest hurdle. Be sure to obtain a good afr gauge.

Good luck!


I was talking with my dad and we have come to a conclusion that iam going to use a 65 dart its one of them early "charger darts" as it use to have a 340 with fenderwell headers so its already cut up. Iam not worried about tuneing it i will be useing a wideband and a friend of mine is helping me tune the carb hes running a homebuilt procharged 427 that runs low 10s traction limited that is a street car. This car is basicly going to be an exsperiment for me to learn and later on maybe throw some boost at 414 stroker.

So you think there will be a big differnce by going with the 360 i was thinking maybe a 50HP difference between the two lol but what do i know thats why iam asking lol. Probley stick with the 273 to learn with as its cheap no sense in breaking the magnum where the parts are more exspensive
