LT1 cam in a GEN I engine?
LT1 cam in a GEN I engine? I found a cam for a LT1 that is what I want to put in my GEN I 383. The question is, what will it take for it to work? I know its possibly for a LT1 cam to work in a GEN I engine but what do you need to do for it to work? Thanks.
I have a pic of the LT4 Hot Cam and it has a dist. gear on it. So, I would assume they all do consider a lot of people like the Hot Cam in the TPI cars. It would just save me the trouble of calling Comp and waiting for 20 mins.

It will have the gear to drive the oil pump! You can use a LT1 cam in a Gen 1 motor, just have to use retrofit roller lifters.

Because most gen 1 blocks (except some from 86-94 or so) weren't set up for roller lifters. So you have to use the retro-fit roller lifters that have the tie bars to keep them from rotating in the lifter bores.

I talked to Thunder Racing today, they'll just get comp to grind me the same cam I want but in a SBC GEN I style for the same price.

I don't think the EFI cams work well with Carb setups. If you're running an EFI with a TBI setup, you should be fine still. The dowel press and roller lifters is all that needs to be done. You can always use the stock setup from roller blocks on non-roller blocks. Like if it has the provisions for a roller setup, but not tapped out, like the center collums. Drill and tap them and put the spider plate on it. Or you could, between the lifters, drill and tap a hole and use the tie bars. Drill a hole through them, and use a bolt and a spring to keep them down, but able to move up like the spider plate allows.
The retro kits are pretty pricey though, so that's the bummer part.
