It's an auto overdrive from a Dakota.
The cam is an Oregon cam grinders regrind 214/224 .512 lift that I picked for torque that supposed to do 415lbs at 3,500 RPM's.
The bottom is stock but it has the EQ heads with the LA bolt pattern intake mounting.
I think the springs were close but doable but the retainer to valve stem seal was what would hit.
Problem is that the springs suck anyway, so I felt I would be well off doing that Hughes spring and retainer set.
You know who could tell you exact and for sure would be Evan (magnummopar) on here.[/
i ran a hughes .544 lift cam with just a spring change on a stock head with no issues
