Sorry Stevet47..I took too many meds the other day ...Ya can do a lot with an inline...We don't get so radical as to using turbo's as there are many carb set ups that are fun to have...Jack Clifford started making highpo stuff for inlines back in the fifties..Died out for a while but he came back with a lot of new line of manifolds etc in the past few...Jack Clifford passed away recently but the company continues..Plus there are many others that build most everything for GM inlines...Visit "The Stovebolt page" for a good time discussing inlines sixes and old GM trucks....I have collected enough parts and a 1969 C10 truck to build a healthy 292L6 coupled to a saginsaw four speed...Its going to be wicked at low speeds....I plan on using tri-power for carburetion...3 one barrels...Time will tell......
