I am back to the drag strip after thirty years of child raising.  So much has changed relative to electronics. I can catch up to that quickly later on.  I need some base info on chevy small blocks.  I have put together a mid seventys 350 four bolt with a stock steel crank.  I used Arias light weight flat tops and Eagle steel rods.  I have a set of new IK200 Brodix heads, a Weiand Team G manifold, a 750 Holly and Accel ignition.  The tranny is a fresh 400 turbo with a Hole shot 3000 stall converter and everything HD except a transbrake.  This will go in my 73 Nova with a 4.10 ten bolt posi with a completely new rear suspension and Cal tracks. The car will not be street driven.
I need guideance with the rest of the valve train.  I want to use a retro fit Hydrolic roller but that is all I know at this point.  I need help with roller rockers and the decision about ratio.  I am pretty sure I can use 1.6 but do I need to?  The springs on the heads are good for a Hyd roller so I am good to go there.  Also where can I get info in the changes from the old small blocks thru LT1 and LS? and so on?  I do not understand the differences other that the obvious fuel injection and etc.
Thanks, Wink
