    A quick question about the 2F hybrid motor. I was wondering if any year 2F block will work with the 3FE head. If not then what years will fit it? Thanks.

    Not any 2F block. I believe the latter 2F block (1982+) maybe? Someone will have the exact date.

    Nope, I'm actually running a full 3F-E, but there are several people LCML and here that are 3F-E'd head and latter-model 2F blocked.

    i guess this is just about gainin compression and stuff like that?

    if so, what all goes where to improve performance?
    (just askin cause it seems like y'all would know)


    thanks,

    I thought it was how you can do a Toyota fuel injection install? Isn't the 3FE injected?
    Ed ???

    The 3F-E is slightly different. It has a shorter stroke and therefor can gain slightly more RPMs, and thus slightly more HP, and less displacement. Torque curve is a little flatter and lower throughout the band IIRC. It is injected as per the -E designator vs. the pure 3F.

    It's a GREAT engine, don't let anyone tell you otherwise; those who have 80s curse the 3F-E in them because of course the 80's a heavy beast; they obviously never drove a BJ60.

    The 3F-E is on par with reliability and longevity with the 2F.

    yeah, good call degnol, ha ha (kinda forgot abt that part too)

    i just remember some of my ford buds puttin 289 heads on their 302s to gain compression and stuff like that,
