well its a 91 351w block bored .30 over. its has about 11:1 compression ratio. As for hp and tq im not sure because i just have a custom tuned chip for my mods. I still have to get a dyno tune down the line because i plan on throwing a better intake manifold and i plan on spraying it. The best i got out of it, which was my first time at the track with the motor swap, was a 13.6 at 106 mph. That was with a 2.3 60ft. Bad tires, bad suspension, no tune, and worst of all bad driver lol but i should be able to get this thing in the mid to low 12's comfortabaly with mickeys, control arms, subframes strange adjustable shocks and the driving experience with the new motor
