Its is a real gm hei I have a spring and weight kit but I don't mess with the heis that ofton so I would have no clue ware to start in my last motor I was running a old school dual points Set up
What should i set the Initial timing at on the Monte? Is a mild 383 .030 over with a 268h comp cam other then that its stock besides headers and roller rockers ect... Its a new HEI gm distributor
Most headers will fit a Monte carlo,Headers for Chevelles 1964-1977,Camaro 1967-1981,1970-1977 Nova/ChevyII and all full size B-body cars 1968-1979 some might have to be dinged to clear the steering shaft but they work
Ya the truck it came out of had this jb weld or some other kinda of glue around it looked like the smashed the hole out with a hammer and glued the radio in people now a days if you cant do it right don't do it at all
For a mild street car you don't need a roller cam or roller rockers jest get a 268h comp cam or the 268xe its way better then stock and isn't to wild great street cam
If you go the 383 route you will be happy trust me I have a 383 in my monte it don't get much better for chevy 350 pm me if you have any ?s about the 383 Set up iv bulit a few
Ya i jest bought a B&M renew kit and shift kit it came with easy to follow instructions that any one with basic automotive knowledge could do it with no problem
Mines a th350 i would assume that the th400 kit is some what similar
I tried to put a cassette player in it i got with the car didn't work so i started cutting, Well tried a hack saw blade to cut the metal didn't work so i pulled out the cut off wheel and started cutting away then i trimmed it with the hack saw blade and filled down all the sharp edges looks pretty good the it wired in nice and easy my station didn't come in(92.1)will see what happens on the road with it
