66 Valiant 6 to V8

go big LA..forget the B/RB. Youll never reap the benefits of a big block power to the ground as the car is too light. Flame me but I been there, blip the gas in a left hand turn and the rear will swing out like your on ice (451 w/3.91 and 2800 stall). LA's can go out to 426 with a 4.125 stroke crank if your a cubic inch counter but a 360 will roast them just as well without the B header headache. Id do a 360 roller: plentiful, no 340 tax and has great heads. keep with an A904, thats all you need and they fit better. 7.25SG a minimum, 8.25 is still somewhat affordable and will bolt in but youll lose your limited 5 on 4 rim selection (bummer...?) Front disk from an Aspen in BBP, now you have 4 matching rims. Use the thick biscuit mounts. not the "ice cream sandwich" ones. Itll give you 1.5" more lift off the center link. K's were the same. The center link had a dropped middle for the V8 cars but you can use a straight one with a front sump pan and the biscuit mounts. may have to clearance the pan just a tad with a BFH in one spot 1/8 inch but probably not.
