SBC how much cam can I get in 9.25 deck block with 4 inch stroke 6 inch rod
 
I'm building a 440 cubic SBC and it has a 4.00 stroke 6.00 rods 4.185 bore I run a .900 base Circle solid roller cam and would like to get 850 to 900 lift just wondering if it will fit in my combination without hitting connecting rods thank you

You can look at the Callies Ultra offset rod to help. Also consider the lobe you will need to get .900" lift. You will probably have to have a bbc journal cam I believe to get that much lift in the block even with 1.7 rockers. At .900" with 1.7 rockers it is a .529 lobe.

I have a 50 MM camshaft that is .850" with 1.8 rocker ratio.

It was in a 9.325" block and raised cam.

It had a 4.125" stroke crankshaft and 6.125" Callies Ultra rods.

Also have a timing cover and timing chain set to go with it.
