heck the perfect combo in that RR would be a 9.1 360 6 pack! Yea 360 6 packs are some running engines...with a RR raised hood all of that will fit under the hood....that would raise some eyebrows...plus the combo works good in a heavier car....running on the 2bbl cruising and then kicking in the outers vacuum controlled, a nicely tuned six pack small block car will run some numbers...
