lt1 cam and 350 block
not really, the lifter bores on a roller engine are not completley round to keep the lifters from rotating. however the LT1 cam has no distributer drive for the original SBC.

lt1 cams do have a distributor drive just like any old style sbc. i gave a friend one to run in his tpi 305 ,and worked great. the cam is a hydraulic roller and requires hyd. roller lifters which tpi engines already have. the lifter boars in an lt1 are round just like a reg. sbc. the lifters are held in place by flat plates that slide over the top of the lifter which inturn are held down with a tray that mounts to the block by three bolts in the bottom of the lifter valley. old style blocks do not have these three bolt holes. their maybe and after market set up for hyd. roller lifters that doesnt require this. the lt1 cam doesnt have a fuel pump drive but if your running an electric pump this wouldnt matter.

also an lt1 cam is recessed in the front to clear a plate mounted to the block to keep it from walking. it works fine without it in an old style block, but an old style cam will not work in an lt1 block. unless you donot run this plate. hope this helps.
it dosent really matter because the old SBC fuel pump is driven off the crank. the old retro fit hydralic lifters have a horizontal bar that goes between the lifters. this would be what you do when putting any roller cam in a non roller block.
edit: nevermind im thinking of a y block ford engine. the chevy fuel pump is run off a lobe on the end of the timing sprocked on the cam, which as long as you are using a old SBC timing set you should be ok.

the lt1 cam will work in any small block. i have one in my 91 block, and i test fit it in a 76 350 block. it does have a distributer gear, but no fuel pump lobe. the pin for the timing gear will ground shorter, and you will need a cam button to keep the cam in place since the older blocks don't have the came retainer plate. and you'll need retro fit roller rockers for the older blocks, 87 and up block can use the gm rockers.
i'm running a 91 block with vortec heads and i used a 94 lt1 cam so i wouldn't need to machine the vortec heads for bigger springs.
