1'st of all about your trailer, ya you will need to take the wheelie bar off to fit in the trailer, just like our 225" JF, that weighs 1450, with driver, and an all iron SBC injected on pure alky, running 7.0's at 188 to190 mph. I help crew on a A/ND, that they run Comp elim, again injected iron alky car that they put the car in backwards [ back of car toward the front of the trailer] , then move the front on the race car off to one side so they can fit a ATV quad next to the front end. They put the quad just inside the back door so they can unload it easy and load last. Neil & Parks has run 6.87 at 197 mph with their A/ND [ JF] 225" with a 387 ci iron SBC making 900-1000 hp weighing , with driver, 1365 lbs and running .967 sixty foot times.
I suggested 225 because of your BBC will make more torque than most SBC JF combo's, and it will try to bring your front end up. It's all about car balance.
Mike Chrisman, Art Chrisman's, son has a JrFueler with a 410 ci BBC that weighs over 1550 #,and has run 7.20's on injected alky, and I think he runs a 4.30 gear and JF rules limit tire to 12" and 12" wide wheels. Most JF cars are running the super light weight [ 22.5 lbs] Goodyear D2585, 31x12x15, good for tire growth. Light tires take less HP to spin, ie , one pound of rotating weight is equal to 9-10 lbs of static weight. the old saying is if you take 100 lbs off your car you will pick-up a tenth.
I have 31x12 and 33x12 GY's in stock, I had to special order them , because GY has these two sizes on an inactive list.
The two used Parks designed FED cars I mentioned are 225", that is the max limit for JF and other classes too. If you build or buy a 225" it will be easier to sell, when it's time.
