My main two problems are that i mounted the motor to fit just right and have clearance everywhere esp to get out the trans bolts. So it mught be forward in the engine bay alittle bit by and inch or so. Dont know. Plus its a wagon and very low to the ground up front. so i dont want longtubes have dealt with them on my 73 mustang and they scrapped all the time. Im looking for low to mid range power. Its a street car that i would like to take to the track every once in awhile. I was looking at fpa tri ys. They look like they are good. But dont know if they will fit right.
