I am in process of rebuilding a 78 3.0 and dropping into 77 narrow body with the following base line mods.
New 9.8 C/R Mahle cylinders and pistons, carrera intake system with electromotive ECU and crankfire ignition, wide band Oxegen sensor, cam sensor(sequential), DR-20 cams, SSI's and monty. 90% street, 10% track
Need to replace fuel pump and supply and return lines to tank. Will stock carrera fuel lines work as routed on my 77 chassis?
With ethonol creeping into our gas, I plan on installing fuel water separator. Mount on line or load side of fuel filter?
Undecided on carrera oil pump or 964 pump. Sound recommendations?
All machine and balancing work will be done by comp. engineering.
Looking to build a strong dependable 240-250HP engine.
