well i though id start a project thread since this is going to be awhile. i have a 99 cherokee 4.0 4x4. i say 4x4 because people always ask when i say its lowered. i am currently building a 4.6l w/nitrous for now to add a supercharger later.
right now engine is basically stock with cai, tb spacer, 180 t-stat, a/c delete, dual elec fans, magna flow cat, 40 series dual outlet muffler, also have cutout after cat, and iat relocated. i have a 7120 head being ported right now with 1.91in 1.56ex valves, going to use mopar perf. springs, retainers, and keepers. comp 231 cam and a knock off ebay header for now. also getting the tb and spacer punched out 60mm through. the upper end is this years project ill have pics soon
slight set back the machine shop is taking longer than i though on the head so i decided im going to just get the block around thanksgiving and build the whole engine. so whats the best cam/crank bearing everyone is using?

I'm building a 4.7 stroker with Clifford intake & headers/ 390 Holley Carb & running a 270 Isky cam. This is going in a 1936 Dodge 2 door sedan I'm building.
starting to see some progress. i have most of the top end just the rockers and push rods to get. i have to go pick up a spare engine i just bought this weekend, so after some disassembly and my pistons get here i will be back at the machine shop for bore and decking. new pics soon
the intakes are just melling 1.90 and the exhaust are stainless mopar 1.56, the head was just surfaced and exhaust seals ground bigger. i will gets pics of the ports when im finished, they are going to match the gasket, has anyone cut the valve guides down to far?
I wouldn't advise doing that. You lose support for the valve stem. It can be better shaped to channel air around the valve stem as opposed to just having an exposed stem. Take a look at how companies like Edelbrock, RHS, AFR, Brodix, etc do theirs. Here are two examples:
