Thanks Brendellajet and Jrork.I'd like to go with 2 1/2 angle at least and am concerned with the minimum clearance needed between rails in a tunnel for correct motor plate mounting because the motor sits so low.Anyone know (about) what the minimum is needed between stringers in a tunnel/picklefork? (bbc with top mount starter set up) Thanks
ihave made several rail kits for the warhawk boats both tunnel and gull wing , their stringers are set on 24in, spacing, i also opt to use the 2 1/2 aluminum angle. i do not have a clearance issue with them even with an oem located starter. if you use a top mount you should not encounter any clearance problems. i have a line drawing that shows the width of a bbc at the dowel pins as 15.38 wide approx. watch your oil pan clearance on the front of the pump intake. if you need any help pm me.
