k, quick question, what years, if any, did a 351w come with fule injection and 4bolt mains, i knew a few had extra meet on em if u wanted to add the extra bolts, and some had partial 4bolt mains but i wanted to know for a future upgrade.
All 302w and 351w have 2 bolt mains except 302 BOSS and the SVO blocks. Fuel injected blocks never had 4 bolt mains as they were mostly used as truck motors in the US and were not really considered by Ford as a performance motor especialy since the release of 4.6 and 5.4 modular motors.
ok, so with the use of that link, i read about the early blocks being stronger,...go fig rite, lol, anyway i can use fule injection stuff on them if i have a fulie manifold rite? what about using roller lifters?
Std roller lifters WON'T fit as the bores are too short and lifer pops out.The hydraulic roller lifters are somewhat longer...Why pushrods are so short..
An aftermarket cam/ lifters can be fitted but they have a small bass circle.Not realy optimal for hi performance, but o/k..
