post your results when you get the distributor locked out and the carb resadjusted.
Don't forget the GM starter motor brace. If yours is missing get one.
The fact that you are mixing your fuel to get the required octane for this 11:1cr motor
shows you are on the ball. It won't take much to get er dialed in.
re: solid cam. Solid cam rev higher and make more ultimate power.
A big solid cam of comparable .050" duration won;t have any more low end power than the hyd you got now.
a big cam is a big cam.
And 16deg inital is your main problem. It will be a whole different beast with locked out timing 32 to 36deg at idle.
I prefer a solid lifter cam too but my 400 with a very similar hyd cam has a ton of low end response
and will yank the wheels on launch. It has lightning fast and smooth throttle response and plenty of low end.
Big cams, whether hyd or solid, want and need a lot more idle timing than 16deg or they are very lame off idle .
fbird you know better than that,you know how a hydraulic lifter works and the compromise you get
