I know I've preached this before but in 25 yrs of racing we have raced
1yr hobby stock
Several yrs NASCAR MODIFIED
Several yrs IMCA modified
Several yrs UMP modified
Several yrs IMCA late model
And several yrs CURRENTLY running UMP late models
in all those yrs the ONLY thing to really ever have any control over what we spent on motors besides claimers (wich most guys consider against the code of the west ) was when we had to run brick hard IMCA McCreary spec tire. Go ahead n build a 430 ! Gd luck hooking it up !
I'm telling you the old timers on here preach how great the racing was back in the day and they were running injected 283s n 327s elbows up and balls out! And they didn't have a 2 ft wide RR with 5 compounds!! It didn't exist! Take the wing off that 305 and narrow up that right rear with 2 compounds and wAtch .
