x275 with nitrous.
In short... Yah....your not gonna be able to build a 427 motor w/ spray and have it live for a year at a time w/o looking at it every 2nd or 3rd race.
Turbo and supercharged combo's are going to eat your lunch and do it while being 5 x more reliable than a spray motor.
I would suggest doing much more research into the X275 class and look at the combinations that are running, who is winning and what they are using. This way you can determine if you can play in the sandbox with those cars w/o breaking the bank.
Just my .02.
