Heading to the machine shop Monday with the heavy stuff
So they'll need the block, crankshaft, pistons/connecting rods, heads and valves (cam, lifter, rockers, springs and push rods will be replaced).. Right? With that we can determine what machining must take place and what needs replaced?
If I have the heads decked/shaved to up the compression a bit, will that change the geometry of the intake to the extent that it'll need machined also? Should I bring the intake in as well?
Regarding the engine build.
My plan is basically "stock plus".. I want low RPM torque and I'll consider big "bang for the buck" upgrades that make sense and are easy to maintain. I'm a big fan of K.I.S.S. I'll eventually lift it and spin 35's or 36's- so some axle ratio work is probably in my future. Right now I'll keep the 33's and 3.73's.
I've settled on an Engle 5052H cam:
Should do fine for what I'm after..
I'll be swapping out the 2bbl (MC2100 or 2150??) to a 4bbl Quadrajet.. Why? It fits my "bag for the buck" principle I guess because I found the 4bbl spread bore intake in the bed of the truck and my reading suggests that upgrading from 2bbl to 4bbl give you a nice power boost on this 360... Can't afford a TBI and would prefer not to drop several hundred dollars on a performer intake/holley..
I'll put the iron manifolds back on. Sounds like they flow nicely and will be fine for this build.
See that part at the base of the passenger side manifold? The bolts at the pipe flange were frozen hard core when the boy and I yanked the engine so we unbolted it at the heads and just left it.. I finally got around to working the thing free today and notice a strange part on the end of it between the manifold and the pipe...
Closer examination revealed a spring actuated butterfly valve.
HAH! Is this some kind of trick used to pass emissions? Would it essentially cut emissions in half when it's closed?
Too funny.. It won't be going back on but I got a laugh outta that.
