The 1984 5.7L cast# 14010207 engine is dead. It is attached to a 574SPHRCRA OMC 800 stringer outdrive in a 255XL Regal. I have downloaded the sterndrive service manual from this site. I have found a 1994 L05 engine in a tornado ravaged chevy truck. In 86' the rear main seal changed from a 2-piece to a 1-piece changing the flexplate bolt pattern. In 87' the mounting angles of the 2 center bolts on each side of the intake changed from 90 to 73 degrees when valve covers changed to centerline bolts.
I want to do an engine(long block) swap and reuse the old intake and 4bl carb along with the old distributor/coil. I would rather use the newer heads as the 84' heads are cast# 462624 and these have a reputation for cracking.
To my questions: (1) Is the flexplate bolt pattern change a problem mounting to the 800 stringer?
(2) Is the seal change a problem if I should need to reuse the old oil pan for some reason?
(3) Will I be able to use the old intake with the newer heads so I can use the carb rather than TBI?
(4) 97'-03' Gen I truck engines were Vortec with significant power increases. Should I consider looking for one of these or is this just compounding obstacles? (I know I would have to get an aftermarket carb intake to do this)
I am also looking for procedures/manual for engine removal/installation pertaining to OMC 800 stringer and 5.7L chevy. The sterndrive manual I downloaded is mostly removing and reinstalling drive components only and at this point I'm not sure if I even need to remove the complete drive in order to pull the engine. There tends not to be a lot of wrench turners on any Regal boat forums that I have seen so far. If someone could point me in the right direction it would be greatly appreciated.
Thanks, Jim.
