Just me wondering if you have done the post-mortem on your corpsical yet and what the verdict on that dead cylinder proved out to be?

The OP doesn't seem too inclined to reply.

I have the same 350/290 , never been happy with the Performance (dog) so currently planning a revamp .
replace 76cc heads with 64cc to bump CR to 9.2 with a thin head gasket . also ditching the factory exhaust manifolds for Smog legal shorty's (california)
Here's a nice right up by MotorTrend on this motor and getting more out of it . https://www.motortrend.com/how-to/350290-crate-engine-project-great-part-1/

Like others said , investigate why a dead cylinder , could be as easy as stuck valve, wiped cam lobe .. pull a valve cover and figure it out .

3.42, by all accounts, is a nice ratio for both cruising and gittin' 'er done. Have you decided on what version of a limited slip you plan to use? Asking because it is a project that i have been thinking about for a while myself. There is a spare 10 bolt on my storage rack that could easily serve as a candidate for the work.

I'm curious if anyone else has dyno'd one of these. I usually take westech at face value, but I have a hard time believing 320 HP with just headers.

Still too expensive, unless you place a premium on an "all new" engine....IMO
