408+stock heads=drivable??? i have about 108,000 on my car and am looking to spend about 4500 on my car this year.i run the car at the track about 3 times a month.the way it is now it shifts around 6600 and i'm alittle worried about the bottom end.my oil pressure hot has gone down from 40 psi 2 years ago to 25 at idle.so this brings me to my question,if i spent the 4500 on a forged bottom end(408)and reused the stock 98 heads would the car be tunable?i don't want to spend the money and have a car that runs like sh*t.i don't mind leaving power on the table if the car runs well.i was thinking about a 408 with a cam appropriate for the displacement.this would leave me a nice power gain later when i could afford a good set of heads.is this a viable option?if this would work what kind of power would you think it would make?if this won't work i'm just gonna do a set of nice heads on my stock shortblock and hope for the best.thanks in advance

i'm not worried about how much power it would make with the 98 heads,just if the stock heads will cause a drivability or tuning issue on a 408 with a good size cam.if i could do heads at the same time i would,but i have a limited budget.thanks for the response
