Im dropping a 98 gt motor into a 99 gtp. the gtp split the piston in half because the previous owner is an idiot. Anyway i got the GT motor for free and it runs strong so thats why its going into the gtp. I plan on top swapping it later with a series 3 GTP top end when i have more time. everything should bolt up correctly if i have done my research right. just wanna double check with some folks who have more experience than me
