So it's not legal to run a 38- 23 hp vanny in Bp class but you can take a 35 cube, 18hp -20hp vanny and bore it out and drop 38 sleeves in it. Same as the 44 cube intec and putting 49 sleeves in it. So what happens when you get caught by tech and does tech find these things out at stabil series races?
Never seen anyone caught back in the day we devised a tool to check header with as the ports are wider, then argument was they were only running the heads. Thats as far as I know it ever went. What you stated above is correct though you can bore one but you cannot run a true block. DUH whats the difference in the end except amount of money spent.
