I am new to this forum. I have a 76 bronco and put a dss 331 bullet short block in last week. I have trick flow twisted wedge heads, an e cam advanced 4 degrees to lower the power in the rpm band. a stock 5.0 intake w/19# injectors. An x pipe with no cats. The engine should be around 10.5 compression according to dss with the twisted wedge heads. I have the timing set at 4 degrees right now with the spout unplugged. I smell fuel at an idle and it does not pull quite as well as I expected. The egr is bypassed and has an egr eliminator built into the RJM harness. I thought I would need 24# injectors and it does seem to lean out at higher rpm but I can really smell gas at idle. No codes except egr not working because of the bypass. I have the stock fpr and msd fuel pump. new o2's. Any idea what could cause the fuel smell at idle and should I get 24# injectors and new mass air calibrated for them. Thanks for any help
