and this one http://www.sdpc2000.com/cart.asp?act...id=128&pid=110

the one says its a great replace ment for a tpi 305. but i have a 305 tbi. and i was just wondering if they will work. thanks

 

The first one will work no problems, everything will bolt right up, just need a new knock sensor, maybe some chip tuning/bigger injectors for it (I'm not a TBI guy, you'll have to take that up with someone else).

The second one is an older block, having a two-piece rear main. You'd have to buy a new flex plate and get a different intake (old bolt pattern style), and I'm sure there's some other things I'm not thinking of right now. You'd be better off getting the Caprice replacement since you'd have to buy some stuff to make the second one compatable anyhow (like I mentioned, intake, flexplate, etc). Not to mention, the second one is rated at lower HP also. If you swapped in a little better cam into that LO5 you should be happy with it.
