I bought the Eagle 408 stroker kit with H-beams.I,ve never had the engine dynoed,but have ran [email protected],1/8 6.83@100mph 60fts 1.50.I run an 8inch Coan 4500 stall with a .631 lift solid roller cam.Eddy heads mildly ported.
The guy at Promax likes the Eagle kits as well. Just wanted to know if one combination worked better than others. I guess good parts, and part selection with a good local machine shop is the key to a good strong motor.
