Thread: 383 Stroker- cam clearance

scat makes a rod that takes a cap screw and the under of the head of the cap screw is i think about 1.400 were many are a long 1.600 bolt and with the cap screw there on need for side nipping the head of the threw bolt. that needs to be done with a stock rods. the scat stroker cap screw rod #scr5a7 for 5.7 or #sc6a7 for 6.000 are much shorter were the cam can hit. the hyd roller lifters have a 700 wheel diameter . i would be never carfull going to small base cam . i built 383 with much bigger roller cams then with you are using with the scat cap screw rods with no work needed or the comp star rods will give you more room as well or just use another cam
