brianspony Posted July 24, 2007 Report Share Posted July 24, 2007 Has anyone read the article on supercharging a 289? 340+ hp. Anyone have any idea of the cost to have it done? Would have to lose the 3 speed standard though for that upgrade. Link to comment Share on other sites More sharing options...
Joe G Posted July 25, 2007 Report Share Posted July 25, 2007 Yeah, just read it. Sounds cool. Man, all that power with such a light body would feel quick. The C4 should be able to handle the power, but I'd go with a good Toploader or a T5 if I had a manual tranny. They post the web sites for the products. I guess just check them out to add up the costs. Link to comment Share on other sites More sharing options...
drlovegun Posted July 26, 2007 Report Share Posted July 26, 2007 I read that, wonder how itll do with my 347 stroker? Link to comment Share on other sites More sharing options...
carnut Posted July 26, 2007 Report Share Posted July 26, 2007 A supercharger on a 347 should be fine if you used a really good crank. IMO, a reground stock crank won't take much in the way of power adders for long. Link to comment Share on other sites More sharing options...

I have a new Isky cam that we have installed. Induction is BDS 6-71 supercharger 5% underdriven, two 600 dps that have been blue printed for the altitude here.High volume oil pmp & water pump, 3/8 stainless steel line from the tank to the carbs, High volume mechanical fuel pump from Holley part number 12-289-20, 1969 top loader 4sp, 2:78 first gear. 9' ford with 3:50 gears.
