Ok I have a 305 TBI with a 5 speed (not that that really matters) and the first question is, is it a hydraulic flat-tapped cam or a hydraulic lifter cam, im 99 percent sure its a roller cam since after 87 they all came with them, but somebody told me that was only for the TPI cars and that the TBI cars had flat tapped cams. Somebody please clear this up. Secondly, I wanted to replace this cam and some new lifters with one that would be great for a 350 I plan on swapping in the future, but also one that would work better than stock for my 305. If it does not come out to the best performance for the 305 but is right on the money for the 350 id be happy, just have to get rid of the stock one right now. I was lookin at a Crane cam with duration @ .50" intake 222/exaust 234 with lift at intake.467"/exaust.494" (rpm range should be 2500-5500)
so I would like to know if I can run this cam on my 305 with no to minimal problems, if I do run into problems what would they be. I will also be putting in some Rhoads lifters. Thanks for any help guys.

it is definately a roller cam. You might want to look for a used LT1 cam, .447/.459 lift and they can be picked up for about 50 shipping on ebay or www.camaroz28.com classifieds. That is the cam of choice for most people with a 305 TBI.

Ya i know but that cam seemed a bit mild for a 350, which is why I guess so many are for sale, the cam im lookin at would work then or not?

Edit, nevermind it's a roller not flat tappet.

im using the LT1 cam when i swap a 350 in this summer, also it should be good when it comes to CA emissions.

Alright I know about the Lt1 Cam, whats highest amount of lift and duration that I could throw on the 305 with stock heads?

are u planning on doing any chip tuning, because almost any aftermarket cam is going to require alot of it.

The first cam you chose, the 222/234 is way too big for a street driven 305. That would make for a hot 350 thought. I ran a zz4 cam in my 305 TBI for a while, specs are 208/221 and that cam ran bad under the stock tune. For the money I would go with the lt1 cam, like everyone says and then buy a new cam when you get the 350. At most you would loose $50 buying the two cams as appose to just buying one for both. I would save you the problem of running an overcamed 305 or a weak 350.
