I had a 485 cheetah I ordered from trinity and it just sit in the box which I just recently sold, I never installed it because I was trying to save and buy other critcal engine parts like override tranny, lockup clutch, hinson basket pressure plate etc....But I changed my mind when I saw the dm cheetah cylinders and now I have started my complete rebuild of frame up. I just recently powercoated the stock frame. Im trying to get ideas so I know what I need to purchase.I couldnt make my mind up on engine size until now. My thing is if your building a drag engine and your already spending thousands of dollar on different engine parts, why not spend a few more and get the biggest available. Now Im kinda stuck on do I really need to fork out more money on a drag frame
