I have a 250 gto replica built by Tom Mcburnie on a 72 240z and inherited by myself about 6 months ago. The car could use some work to bring it back to the condition it was once in and I could use some assistance with pointing me in the right direction. I am in MI( Harper Woods ). Any tips or assitance you could provide would be greatly appreaciated. my car has a chevy 350 bored to about 30 over with a Edelbrock 4 barrel carb that is currently not running right. I have seen a picture of speed racers engine on this board and it looks very similar. If anyone knows of any good mechanics in the area please let me know. I have changed the distributor, plugs, wires, battery, coil, and converted the points to an elctronic ignition yet the car still does not want to start. Any opinions/ advice would be appreaciated.

Thanks, Brian

Start with the basics. Is it getting gas? With the air cleaner off, pull the throttle lever on the carb wide open and see if gas is coming out of the squirters. If not, fuel filter, fuel pump, gas line, carb, and tank all need checked. If it's squirting gas, pull a plug, ground it and see if it's firing. If not, check out the ignition system. If it's firing, check the timing to see if it's within range, say 10-15 deg btdc. If the timing looks OK, make sure the dist isn't 1/2 round out of time. Get # 1 to TDC with both valves closed, look to see if the rotor is pointing towards the terminal #1 wire is attached to. Next would be a compression check, then a timing chain check. Was it running when parked? If so, it's likely fuel related. If not, it could be anywhere, just have to start eliminating stuff and narrow it down.
