I have Fentons on my 37 and had been looking for a Vette manifold so I could heat the intake but after I found out how much money they bring the 40 something dollar heat kit for the Fentons was way more in my budget,I wanted the Vette manifold to tell the so called experts I usually run into at shows and cruise ins it was a original accessory to try to fool them more then with my 235 that I made look like a 216.
