Well while waiting for the hub and stuff to get here.I decided,actually could'nt wait to start the manifold I decided to make.cutting the t6 is a b___ch[:@],but I got'er dune.first I cut the outter diameter of the manifold and positioned it on the engine and marking the stub cut out.I then cut the stub hole to where it fit good but not tight.I then marked and drilled the three flange holes where the manifold will attach to the base of the stub.After drilling the holes for the machine screws I oversized to a 1/4 bit to counter sink them about a 1/4 inch in the plate.I noticed that I did'nt really have much flange for the hole(the outside edge was at or over the edge of the base).So I decide to make two backing plates that fit rather nicely between the cooling fins and base backside,one on each side.The center hole was no problem and had plenty on meat for threads right next to the old pulse port.After drilling and tapping out the backplates and center hole I mounted the manifold with 6-32 stainless machine flatheads and marked the carb mount holes to the right of the oval stub where the right side of the venturi and the right side of the stub were even.The reason I did this is because the carb has more sealing surface on the left side,I don't want any leaks.I use and old carb bolt to make a tap the proper size(grind for sides tapering towards the end)Im using bolts right now but,will be using studs later.I then used the old metal plate that was between the carb and rubber poulan junk and marked a heat shield out of 1/8 lite ply.This is a tight setup and I feel like its much more secure than set screws on a cast stub.Here are the pics I took along the journey.Any questions I will be glad to answer.
