Lock out the distributor mech adv system (full locked 34 to 36deg timing).
You can retain and use the vac advance (ported)
use a 4.5' power valve or 4" step up spring (eddy)

5.13++ gears. 3000+stall
So I removed the oil cooler and related lines and sht, changed the oil with 10/40 today, and let it get up to operating temp, now it shows app 15-20 PSi at idle, 10-15 in gear, no funny I'm gonna run 20/50 in the summer and not worry about it. I also have another set of 416 heads, my buddy is puling his 305 from his olds cutlass next month ans that's the heads on it, runs good, low mileage so I will really really go nuts with the porting this time, and use the springs, valves, and guide plates from those 882's I can buy for $100. 456 gear, the solid cam you reccomended for my vette, and my converter, and hopefully this whale will move half decent.
