I got 2 LT1 cams, what would I have to do to put one of them in a pre '68 (small journal) 327 block? THANKS!

you're probably going to have to get special lifters, they are taller than stock lifters so you have to get special shorter pushrods fo it. other than that I think it's pretty much standard with installing the cam and such, try calling summit or jegs they should have what you need, or be able to let you know what you need to complete the swap. enjoy the torque :D you'll love it!

hehe. Thanks but I don't have the v8 yet. I'm researching unique engines to put in my YJ. I'm also thinking about a 340 EFI MOPAR Magnum(360 block 318 crank), LT1, 4.7L SOHC MOPAR....

Lots of stuff.....
replace lifters. You will have to get ganned lifters to keep them from spinning in the bores....(pricey)

thrust plate or cam bumper to keep the cam from walking

replace the vavle springs to stronger ones.

replace the pushrods

replace the rocker studs to screw in

install guide plates

install a new dist drive gear

replace the timing chain and gears

you will probably want new rockers

for sure new retainers and locks

My hydraulic roller is a 277/284 .535/.551, it requires 125# of seat pressure so I could have used stock springs. I got retro fit Comp cam hydro roller lifters and shorter pushrods, I got the comp retro push rods and they were two short so pay special attention to rocker tip to valve stem contact and make sure the tip is pushing on the stem and not the retainer. I ran a cam button for the heck of it and a double roller chain.

I am not sure why you would have to change distributor gears unless the cam maker recommends a bronze gear.

If you going real high lift go with roller rockers, if you spring pressure is resonable you can stick with press in studs, but screw in and guideplate is a good idea.

Basically you are looking at 250 for a cam, 350 for lifters, 60-90 for the proper length pushrods and 200-250 for roller rockers...

But man what a difference! :D

It is a good idea to change to screw in studs. Large lift cams put a lot of pressure on them. Plus, with the radically steep profiles of a roller cam the valvle springs need to be stout to keep the lifters from hopping off the cam lobes. Be a drag for sure to pull a stud at around 6 grand or so......:eek:
