Biggest cam on LT1? A friend of mine has an LT1 with a 305 cam, 1.6rr, hooker headers, 3000 stall, 3.73's and just about all the regular bolt-on stuff. He wants to make an upgrade on the cam and he was thinking of a 306 or maybe something bigger. What is the biggest cam you can put on an LT1 with out fly-cutting the pistons? Driveability won't be a concern since its only a strip and street weekend warrior.

you can get into some grinds just above .600 in lift befor you have to worry about cutting pistons....that is assuming his heads and block haven't been touched...if that's the case....a cam that big wouldn't be benificial untill he did some headwork too

I think he is talking cam only car, and whats the biggest cam and most power you can make.
Good luck finding info, If the thread isnt about a catback exhaust and sound you dont get a reply.......Im in the same boat and would like to know also..

If driveability isnt a issue have someone make you a custom cam to meet the needs of the driver.... if your looking for a off the shelf grind then the most people will say go is the GM847 234/242 .576/.595 with 1.6 rockers

i have 600 lift, and when i have plenty of piston to valve clearence. my heads have been milled.
just dont exspect to go fast if all your wanting to do is throw the biggest cam in... probably wont gain much if anything over the 305 going bigger unless you get heads.

I agree cam/heads/intake are the key boltons for "reasonable" priced power but he's asking about cams.

So cams like the 306, 847 & the right boltons will definitely net over 305 as you say.

), I upgraded a couple weeks later with 1.7 Comp ProMag Stainless RRs with better springs, CompRs, 1pc pushrods, guides and PCM tuning, this got me to around 350-355 with the better valvetrain components.

i was putting down 335 rwhp with just boltons so i would hope you were over 350-360 with a cam.
im running an fms cam. 233/241 573/597. you can get away with quite a bit of lift since our pistons are in the cyclinders a little ways.
if he wants to make power he should look into a custom cam. the "off the shelf" cams will only take you so far.

Wow that seem like a lot for just bolt ons. What specifically did you have?

MeanGreen your may try some research on camaroz28.com as well if you haven't already, quite a bit of info on several cams on stock heads of this spec.
