professional help please! I'm stuck.

[da89cup]

I'm running a 351W with stock 5.0 heads, some kind of cam, GT40 lower, cobra upper, 80mm maf, 70mm tb, 30lb injectors, 190lph pump, 1 5/8 equal length hedmans, h-pipe, dynomax race bullets, & 4" tips. I'm not sure if it's a roller block or not. My best time was 14.665 @ 95.9mph. I think that's frickin slow. timing is @ 14, i still have the stock computer. What should I do. I'm thinking of going with 24 pounders instead of 30s. Should I get a chip? Will that make my computer work properly with my mods even though it's a 5.0 computer & not a 5.8, or maybe with the chip I don't have to change the injectors. I think the injectors are too big, I'm running rich so any advice would be greatly appreciated.I'm still running 2.73s, & stock T5. I could throw some better heads on there but if I buy performance heads, I should buy a cam that'll match with the heads for best power. So maybe I should get these rebuilt & ported/polished, the whole works. After the track, i now have blue smoke coming from my driver's side exhaust pipe when i race, could it be the head, my oil pressure is barely over the red line on the gauge but it constantly flactuates. when i put it in 1st & let go the clutch & the rpms drop a little, the oil pressure gauge needle falls down dompletely until the car starts moving. do I need to rebuild the engine? Please help.
