Engine bogs at higher RPM
Hi folks, my 66 El Camino with a near stock 327 high output motor sat for a long time. I started it periodically to keep the battery up and the seals lubed, etc. but hadnít taken it out on the road due to non-op status. I recently switched it to operation status and pulled her out for a drive. She ran great at lower RPMs, right up to about 3500 RPM (no tach so not exactly sure) and then it just kind of bogged, almost like it ran out of gas, but then was fine again at lower RPMS. I drove around a while thinking it was just cold but no, every time I tried to get on it a little, sheíd crap out just as soon as Iíd hit that sweet spot where it would normally scream. Bad gas? Bad fuel pump? Any other ideas?
Many thanks in advance, Rick
