    I currently have a 302 with a TV7701 with a .87 exhaust housing. On the 302 this turbo seemed sweet, but what will happen with a 351?

    Basically any insight of ppl keeping the same turbo from a 302 to 351 will help.

    Turbo specs
    Compressor Housing A/R .55
    Turbine Housing A/R .87
    Compressor Wheel Inducer 2.458" (62.4332mm) Exducer 3.70" (93.98mm)
    Turbine Wheel Inducer 3.60" (91.44mm) Exducer 2.840" (72.136mm)

    Overall combo
    Eddy 170s
    f cam
    Not sure on intake yet probably carb style
    E85 and E85 injection

    Its not a dedicated race car...its more of a street car that I street race. I know the 62mm compressor is small, BUT I'm hoping pre-turbo injection will help extend the efficiency if I try to squeeze out more. I can't find alot of info on this turbo or ppl that run/ran it. Only the boat guy that ran twins on a 540 Chevy. He managed to get 1400 with the twins and 1.00 ex. housings.
