I am thinking about buying a 350 roller cam long block from the YearOne Catalog (Page 106) and bolting it into my 1970 Nova SS, manual trans. According to the Tech department it uses a 1996 block. The engine comes with Vortec Heads and Vortec Intake. Will this engine bolt in without modification using my current other parts or will there be modifications that I must make? I would like to make the swap as easy as possible. I have been told by a friend that I will need a different fly wheel and a melonized distributor. Any and all help is appreciated. Jack
As far as bolting it in it will fit just like your old one. On the other parts the acc. shouldn't be a problem double check with them to make sure there are acc. holes in the heads. I can't answer your question about the flywheel, sorry.
Hopefully we are talking about a gen one SBC out of a pick-up truck, and not a gen two LT-1 motor from an Impala SS. Even though the motor will drop right in and bolt up the Gen-II SBC with OptiSpark ignition requires EFI and an ODB-II computer to run. Even though the 1996 Vortec pick-up truck motor was EFI it was a TBI system which can be easily converted over to a carburetor. The Gen -II small block is reverse cooled and has to have all of the EFI stuff to run.
Steve, thanks for the reply. That is good news. Will the oil dip stick be on the same side? Big Dave, Judging from the picture in the YearOne catalog the long block comes with a knock off generic looking Edelbrock Vortec RPM Air Gap intake manifold. Knowing YearOne I don't think they would try to sell a Gen II block assenbled like that but you never know. Your information is very good to know, I had no idea the two block would look alike. How do you distinguish a Gen II from a Gen I? Anyone know about the fly wheel issue? Thanks again guys, Jack
