1992 LT1 Performance Camshaft
Hey guys! I've really been considering camming my 1992 6speed Vette lately. Basically I've been looking for some more power and to hear some cam at idle. This car is a daily driver. So far its got 15 lbs off the flywheel, SPEC Clutch, a full exhaust, Custom intake lid, and thats really about it as far as powertrain mods go.... Car still has to pass emissions, and has hi-flow cats.
I know what I've been leaning toward, but I would like to know your suggestions. And BUDGET is the key word!
Oh! And what do you guys recomend replacing in the heads?
Thanks,
-Nick

What would you specifically do to the stock heads and the intake manifold? I've built a few performance motors, but they have all been big budget motorcycle engines. I don't mind it being a bit of a bitch to drive either. It just still needs to be somewhat reasonable. I just need to be pointed in the correct direction.

Do you guys think that this cam is too big for a car that will see commute/ street/ and strip use?

And would you replace pushrods and lifters? Or just the Rockers and Valve Springs?

Push rods, lifters, rockers and springs ... any and all of these pieces may need to be replaced depending on engine mileage and general condition. Irrespective of mileage and condition, the push rods will need to be replaced if they are not the correct length for the new cam and/or rockers. New roller rockers would be a nice addition ... they aren't overly expensive and will help performance.

I would recommend 3.73 to 4.10 gears if you really want fun.

If you have to pass emissions (sniffer test) then make sure you discuss that with the cam grinder and you will likely end up with a mild cam to ensure you pass.
I think I go against the grain here but a good set of ported heads(or aftermarket like AFR 180 cc) will make a bigger gain than a cam and stock heads.
For what it would cost to send your heads to Advanced Induction you could have a set of good aftermarket heads with room to grow.
Heads and cam from AI would be a killer setup.I like their cams.

Lots of ways to increase power in the LTx platform but they do get pricey.Figure out how much you want to spend and that will dictate where you go.
