NOT the usual cam advice...

Great post
plan your work-work your plan
the ice of Texas are upon you

OP if you do not have the TBi just skip it and go to the later MPFI
I have TQ on one chevy truck, ported heads, Jones FTH cam, rams horns
and Tuned port MPFI on another replacing earlier TB EFI Tuned port is much better- otherwise stock engine with duals HR cam but not original one 1.6 rocker on the intake
Jones camed motor is better but everything is perfect, compression, heads cam etc TQ has the altitude compensation on it which works ok but not as good as the EFI
but the FI works better in the winter
