I have an 84 Mustang with a 351W. I bought the car and just got it running but havent drove it yet. It has a C-5 in it, question is i know bands, clutches, and converter will swap from a C-4 but if its a lock-up thats in it now what will happen if i put like a 3800 stall in it? Will rebuild of course first. Dont care about gas mileage its only gonna be a weekend driver. Also there's no throttle cable to tranny, will that hurt or will it drive right? Thanks!!
