Updated SPITFIRE HEADER INSTALL 63-66 A-body
I put Spitfires on my 4-speed 340 '66 Barracuda about 10 years ago. I had them ceramic coated because I knew I'd have the car a long time & I didn't want to mess with headers EVER again if I could avoid it. I broke the bolt on my 90 degree oil filter adapter - $70 from the dealer for a damned bolt!!! Instead I put on a shorty filter that fits & works just fine. In hindsight I wish I had trimmed the transmission mount so the 2 1/2" exhaust would have been more out of sight on the passenger side. I use those silver mesh spark plug booties to avoid melting plug wires. I used a mini starter just because it is really busy down there!
