Slant to 318 pondering...just need opinions

Nice looking motor!!

mine SHOULD be around 275 or 300 horsepower

Should i upgrade the brakes? or wait for that? just going to run the 7 1/4 until i source an 8 1/4

Also will B-body small block headers work on an A-body? trying to save money :D
im still running every piece of my slant suspension. drum brakes and 7 1/4 and very happy with it. the headers are my B Body small block long tubes. dont abuse the 7 1/4 and it will be fine. i am using a 26" radiator and fan shroud out of an 86 lebaron from pull n pay , 40 bucks out the door. i did this on the super cheap.
