started building my 89 gt vert, look, im wondering...
are the gt40 swirl heads better then the EDELBROCK performer rpm? i have the F303 cam, msd ignition,9mmf racing cables,BBK SSI intake, 75mm thro body, getting the mass air flow soon, BBK shorty headders, 3.73 gears, pro 5.0 short throw, aluminium shaft by f racing,bbk fuel regw/ gauge,1.6 ratio rollr rockers, under drive pulleys by bbk, bbk cold air intake, still working on exhaust, im waiting to buy the cut off pipes with stock muffler/cats, i dont want it to make a lot of noise when driving..., but when i race it, just hit thatlittle switch...[sm=badbadbad.gif] my engine block is the stock 5.0, stock pistons, crank, do you think i should upgrade these parts? thats all i was going to do with my engine, i wasnt going to do much, just what i already mentioned, but now thats everything is out, im thinking about it.....oh and also, i hear most everybody moves timing on their cars, you think 14degrees is ok, or it all depends on the set up>?
