Installing a 455 in a 55 Olds Rocket 88. Also going with the TH400 Transmission. Anyone done one with good results and fit? My understanding is you have to build the engine brackets, Transmission mount, etc. Also been told power brake booster is in the way and needs to be moved. There is also an issue with the driver's side exhaust manifold hitting the steering box? Anyone do one successfully that would share tips or procedure? thanks in advance.

 

Anyone?????
