BowTie Eater 5 Liter · 09-13-2001, 12:46 AM

ok, i want to get more power out of my car, so once its off the road (oct 23) i am planning on taking the top half of the motor appart.

i want to port the exhaust side of the heads, possibly add 1.7rrs(is it worth it?). What size rrs will i need for the stock heads? is there anything else i should think of doing to freshen up my 175000km motor while the heads are off?

i dont have a lot of money, so i think hand porting the exhaust side might be cheap & effective.

how much power could i expect?

yhanks
