yes , that my buds buddy's car , it uses the same amount of fuel as it did as a v8 hemi . and it makes the same ponies too . it makes so much side thrust from the exhaust exiting on one side it pushes it sideways . there was a guy j roch in santa barbara that built that 4 cylinder . he did a lower end for my salt project , 354 into a 371 for xxo class 1959 n earlier motors only . he was working on a cooler for the exhaust exit on that car . to keep it straight , they turned the exhaust primeries tubes @ 90 deg to the rear of the car , it would glow those tubes white and there would crack on the cool down . j was building a exhaust manifold water box so water could be pumped through it ''to keep them at cherry red , lol'' . j roch (quote) he was a master and will be missed , sorry to say his expertise went with him .
