273/ 2 barrel camshaft options

The cam in post #14 is quite small, may not have have as much 'oomph' as the original cam. That is because solid lifter cams with 018" lash are equivalent to about a hyd cam 9* shorter at 050. So equivalent to a 189 @ 050 hyd cam; equivalent meaning, gives equivalent performance.
Also, using a re-ground cam might lead to lash adjustment problems because the base circle of the cam is reduced in size; consequently, lifters sit lower & rocker adjustment screw needs to be screwed in further to get the correct lash. Ok if there is enough thread on the adjuster.....

I agree with others that the Isky E-4 cam is best. Isky cams are good. If you do not want lifter/lobe failure, have your old lifters re-faced; they look in reasonable condition. Do not buy new lifters, they fail.
NEVER, EVER USE USED LIFTERS ON A NEW CAM....NO MATTER HOW GOOD THEY LOOK.

Hello and good morning, thanks for taking the time to participate here, until I hear from the machine shop on the block and heads I’m at a standstill. But I am leaning into the option of the isky vs grinding the existing cam for the exact details that you mentioned.

Hello and thank you for taking the time to share some very useful info. Until I hear from the shop on the condition of the block and the heads, I’m at a standstill. The isky does seem to be the ideal solution, but as member 4spdragtop had commented, would this fall into “over cam” too much for the simple 2 barrel 273 to handle? What else would I need to do and or change in going with the isky?

Am I understanding that it would be as simple as having my existing lifters refaced and then just installing the isky cam? Will I need to replace springs, push rods and or valves?

This setup would perform ideally to factory specs of what the engine has been its whole life if not better?

Does anything need to change with the timing, cam or crank gears or chain?

I apologize for my stupidity here and for the 21 questions. Thank you again for your time!
