After some thought and consideration I am leaning toward buying the ZZ383 engine from GM Performance at a local dealer. I have considered othe engine builders, but because I live in Canada, import duties become prohibitive to bring in an engine purchased in the US. I can buy the block with aluminum heads for $5100.00 Please endure my ignorance as I ask several questions. Will the stock intake from my L48 perform adequately? What about the stock carb? Should I go to HEI, or stay with the stock points ignition? Will stock exhaust manifolds perform adequately? I have shied away from headers for a couple reasons....longevity and heat dispersion under the hood. I have the turbo 400 transmission with 3.08 rear diff. Do I need to increase stall speed? Would performance be acceptable without tranny changes? Thanks for any input. Ben
