btw no apologies required for the engine mod takeover of the thread, I'm doing the engine in my Bonneville convertible as we speak, 428HO with original 62 heads but I swapped in a 455 crank and cast pistons that result in 9.5 compression. I can't think of the brand but the cam is basically a 067 but with greater lobe separation to address octane concerns, I've run the same cam in a 400 with similar compression and like how it runs and sounds. We have 94 octane here but it has ethanol so we have to run 91 octane to get pure gas.
