chevy 350 questions

how do i figure out what generation chevy 350 block i have, it's out of a 97, but i dont know what it's out of. also, does roller mean it has the lifters with rollers or does it mean something else, and if so can i use flat lifters or do i need the roller ones. thanks

Roller blocks mean it can except roller lifters with out too much effort. If it is a gen I block then, Yes you can run flat lifters but you have to change your cam to flat lifter cam as well.

If it is out of a truck/van it will be a gen I block. If it came from a caramo/firebird/corvette I believe its a LS1 or LT1, I forget if 97 or 98 was the change in motors. I dont delive you can run a flaty cam in one of these motors.

If the water pump is off, look at the water jacket holes. if it only has one hole pre side, it should be a gen I block.

All of those peices are for a roller cam setup. Its a gen I block. Id keep it roller unless you already have a flat tappet cam.

These bolts hold your cam retainer plate in place. Stops the cam from "walking" front to back.


These slid over the top of the lifters to they dont rotate in there bore.


And this "spider" bolts inside your lifter valley to put tentsion on the picter above and keep them from moving

all production 350 1987 and up blocks are roller cam compatible if the last 3 of the casting number are 638 or 880.

the plate that hold the cam in is called a thrust plate. the only reason GM put them in was because of the Iroc Z. they were running into problems when the cars would slow down fast. come to find out without the friction of the lifter the cam would slide out the bores until it contacted the timing cover. at this point it went forward far enough it would retard the distributor advance to the point it would stall. I replaced several that were "Missed" in production
