1972 mach1 351c problem

hello i have a problem with my 351c well here it is i overhauled the
engine bored 30 over 10 on crank got forged pistons and my cam is a
lunati cam with a 572 lift and 268 esh and a 110 angle lobe i realy
dont know wat the lobe means but oki swaped my 2v head for 4v heads
and a torker intake ..... jus wanted to give an over view of wat im
workin with here sooooo heres the problem the engine starts up strong
but sounds a little wierd it start up with the high output timing
setting 13726548 wen i put it in gear it runs but it does not run like
a beast like it was meant to run it jus runs slugish i opend my valve
covers and noticed that the rocker arms are all tight but 2 at a time
ill crank it to cahnge position and another 2 somewhere else are loose
and the ones that were loose before are tight now iono wat to doive
messed with the timing checked vacume could it be the cam is not on
time with crank this is my first cleveland so im a bit hesitant with
everything i do any sugestions to wat i should do the tires wont
squeak at all maby a piston is miss firing anyone else had this
problem my guess is the cam please help

Your cam is too tall & your valves are too big for running much below
5000-6000 rpm. Poor atomization & low intake velocity are your enemies.

Building an engine MUST be purpose-driven, it is a scientific quest, &
even more so with a Cleveland, than with a small block Chevy or Ford.
The 351C needs special attention due to it's breathing characteristics,
and chamber shape & design.

I can't do your homework for you. Get a Cleveland specific engine
building book, read up on mag & tech articles all you can. It's not an
overnight project.

i apreciate the help ima tear apart tomorow and check the timing and
timing chain all the basics and put the roller rockers see if can
adjust them right and if that dont work ima find a better cam for it
and i was reading up and maby a c6 trany witha torque converter should
help and make it run better

The way you are set up now you should have a stick shift or a 3500rpm
stall converter.

Run your cam straight up or slightly advanced, w/ 93 octane or better fuel.
