a nother cam setup ?
i got a 68 camaro that has a 305tpi 700r4 in it, and a set of summit hedders and 23" glass pacs, stock chip and computer and no smog. what i want to do is to get that muscle car rumble when im setting at the red light or when it is at idle. i got poly motor mounts and what to feel the motor shake like my dads truck. the map senser limits me right? any help is good help and thanks for it all the biggests is what i want http://www.geocities.com/claycitydude/68

Yes, if you have a map sensor, it senses the manifold pressure and changing cams to achieve the lopey idle you want will also require a PROM change for the computer.

if you are looking for a choppy idle, just order a cam with LSA of 110, your gonna need to reprogram the computer for the cam, and dont expect it to make optimal power with TPI and a LSA of 110, but it will have that muscle car chop

LSA is lobe separation angle basically it's one factor that determines the overlap between the intake and exhaust. A lower separation is a greater overlap which is essentially what gives you that lopey idle.
I could be wrong but I'd say any cam change, especially going with say a 108 LSA would really require chip work. In which case I cant stress enough the need to burn your own chips. Go to the DIY-PROM board and start reading up and check out the prom burning intro article https://www.thirdgen.org/newdesign/tech/promintro.shtml
By the way nice little project you got there, good luck with the rust I know exactly where your coming from. Got a 69 Firebird convertible in a bit rougher shape, but it's all there. Would have given up on it long ago if it wasn't a convertible

The LSA on it was 108. I even posted a thread about solely it and willie (supercharged 305 camaro) said he knew someone or wondered why TPIS cams made cars run so fast for what they were. I'm not saying running on 108 LSA on the stock chip is perfected, just saying I believe it's possible.
