I havent had good luck with mechanics. I had my 440 Mopar rebuilt a few years ago but a tapping showed up quick. The guy who did it wouldnt honor the warranty. The next mechanic passed away. Next mechanic basically stole my car and $$ for 2 years. I finally got a few dollars to spend on it but need a diagnosis and estimate HERE in Holbrook. At worst 1 of the heads needs to be taken and reworked. No smoke. Garaged in Holbrook. I will be very generous if I can find a honest old school carburetor mechanic. Text me for video. Cash or trade for work, car is not for sale.
