Actually, sitting and reading that whole page again... i think i will go this way for the Omni. Mild ported head. Still contemplating if i should use a ported TBI exhaust manny or my MP long header. The header requires a section of braided flex pipe ($$) and solid front mount to keep it from smacking the firewall. (It's damn long!) I'll shave the head/block to get it to 10:1 (stock is 8.9) and throw in some turbo floating rods. I'm not sure if common block N/A engines have the floaters. 520 trans, maybe 523 if i feel creative. Guess i wont need that 90 Omni harness anymore. Someone wanted to buy it on the other lists... just forget who...
