I am having an 89 model 351w rebuilt and was wondering if I bup the compression up to 9-9.5 and ad an rv cam will the 90 model computer hadle the mods. with out going maf or using a 5.0 computer?
Generally an RV-type cam is mild enough not to send the Speed Density computer into fits, but it's a good idea to check that the cam you're looking at is indeed SD compatible. I wasn't sure about the cam I bought, but I called Crane's tech line and they assured me that the cam I bought was indeed suitible for SD, and in fact was one of the few they had that was.
