Lmao la engine! A numbers matching application or class is cool.The w series heads are assembled using many parts that are very expensive.I have race w2 heads that are so expensive to assemble it’s foolish to even think about.Im not asking because I have the parts list from mopar performance. The B1 ts heads from brodix are the same way$$$$$ w8 and w9 are also big big dollars.old technology as the years progress.I have been racing mopar for 30 plus years
And have tried most combinations.now days it’s a tune and a pulley on these long skirted Gen lll hemi that can handle 1200 hp all day long and still get 20 mpg with the a/c on while having all the options like remote start and DVD players.carbrated is of the museum.The factory 1968 hemi cars run high tens and got 4 mpg on a good day.gen lll 6.2 with some tuning and injectors runs mid 10 and I’m not asking you! Hemispheric combustion chamber is second to no wedge style head not even the 600-13.Remember it was hemi that powered nascar to all those victories and hemi that powers all the top classes in drag racing.16 parts air to 1 part fuel only the hemi can get close to this.a very long vacuum signal with the hemispherical combustion chamber.again I’m not asking bench google racing people.
