e303 w/ 1.7's on 351 heads that are ported. if you got shorty headers (i have jba) you will get alot of compliments. i have good torque once i hit the 2,5 mark and pull to redline. although i have just snapped yet another stud on the rockers so i will reccommend getting a stud girdle just so you save yourself the trouble and the downtime.
