LT4 hotcam in 305 TPIthzzz28man 10-02-2003, 11:32 AM I recently purchased a LT4 hotcam to put into my 1991 z28 w/ 305 tpi and 5 speed will the cam go right in w/ no probs? Any tips? Do I have to take the intake clear apart or just take the whole thing off? thanks RobsWS6 10-02-2003, 06:03 PM You'll have to cut the pin on the end as its long to drive the opti spark. Other than that, its a normal cam install. kraftopia02 10-02-2003, 06:18 PM you'll have to remove all the intake stuff, distributor, and allthe valve train as well (lifters, etc.) Then just weasle the cam outta there, lube the new one up and weasle it back in. Be REAL gentle. The insturctions in the hanes manual are pretty good, actually. kraftopia02 10-02-2003, 06:20 PM also, make sure you get the timing aligned correctly when you install the new cam.

Your stock cam is one of these, 305 5spd / 305 AT .350 .384 305 G92 5spd / 350 AT .413 .428 | ||
