I do get good performance from the stock manifold and carb..also thinking of upgradings the distributor shaft and housing and coil instead of the 3 plus for the rpm intake..that way I can see everything when I install the shaft onto cam..
As far as I know, all SB''s have them. They are not very big. maybe 3/16" - 1/8" in dia. , 1/2" - 3/4" long.
the pins are captive in the block. The holes in the intake are like 1/4" in dia. for clearance on the pins.
I will check when I take off and get some pins to use...they should be long enough to go from block threw cork and into intake.. so I'm correct on what you said
affirmative
Question..on the intake manifold is the water jackets only on the ends or is the middle one also a water jacket or is middle one a heat transfer???
yes, water jacket passages are at the corners of the intake, and the center passage is for exhaust cross-over heat.
Was wondering why with temp gun it was bit higher at those ports..lol.. guessing no rtv around those needed??
"needed" is a relative term. Myself, I do put a little rtv around the water ports. It may not be necessary if you are using the "print-o-seal" gaskets which are manufactured with a bead of sealer around each port, already. I haven't done anything on a SB in years, so I don't know if they still make those gaskets anymore.
