i already know how to build high power motors. im just wonderin what other peoples take on this is. aint payin extra nothin for polishing or porting i do it my own self.
by the way 358 is my final displacment not horses.
also i aways been told either port or polish but never do both. when you do both you will not have enough turbulance to properly mix fuel and air.

i build trannys fora livin and its gettin a th400 that will about throw you thru the back window when it shifts. i would like to get away from the torqe converer and put a hydrostik in it, thats basicaly a clutch if a dont know, but i aint seen one in years.
