In your opinion, how much cam is “a lot of cam”? I’m planning on either hydraulic roller or solid roller, neighborhood of .550-.575lift with duration in the mid 220 to 230 degree range at .050”. In terms of the cylinder head, I’m going to divide the intake port (this is going to be port injected EFI), and I plan on brazing up the roof so that I can raise it, and fill the floor. The engine will be turbocharged, and I plan on building a nice header and fabricated intake manifold. With these modifications, I should be able to get the port to where it needs to be to stay quiet and not choke. If there’s something I’m missing, please let me know! If this engine platform isn’t going to cut it, I can build something else. But, I really like taking the road less traveled, and learning in the process.
