Hello all! First time buyer, 1985 Pace Arrow 31'

I had an a 1984 Allegro with a GM 454 engine, bought it new. The engine was a nightmare! Went thru 3 sets of headers until I spent the extra bucks to get some stainless steel headers, It had massive vapor lock problems from day one in hot weather and at altitude. Had to put in a second fuel pump at the gas tank to help with the vapor lock problem. The heat problem continually fried ignition wires etc. You couldn't give me another GM 454 engine!
