1987 21 ft scarab1 perf questions 350 mag
hey guys just wondering what you 350 mag owners do for some added performance. it went strong all summer long at 54-55 on gps with a 2yr old long block and a 21p mirage plus prop. but i just tore down the motor for a long winter overhaul. block is .040 over 1987-1995 block and the heads are 1987 and up center bolts (nothing fancy). just wondering what perf mods work on a marine setup heads intake cam etc... looking to squeeze a few mph on a budget. also the boat has threw hull with stock manifolds. any suggestions woul be helpful on which route i will go.:readinghelp:
