Ok guys, looking for a Cam / valve train recommendation.

I'm doing this work on my project 9C1...main goals are to keep it affordable, learn how to rebuild the top end from the heads up (never done it but I've been reading alot and have decent mechanical ability), and to gain some power over stock.

I've got a set of aluminum 97 F-Body heads, 561 casting which, according to LE, are the best flowing stock aluminum heads. Other than that I've got a set of tri-ys set aside, will keep stock gears, stock RPMs, and will have the PCM programmed after the rebuild.

I know a stock aluminum head is not an upgrade from iron...but if I tailor the valve train to aluminum will I at least not lose anything? They will up the compression right? Not looking to spend alot on head porting or performance heads and I already have the 561s laying around.

Was looking at the LT4 Hot Cam kit on Summit...with the roller rockers and all... as well as some comp cam kits.

Again...not looking to make crazy power...but it'd be nice if it was over stock.

So looking for recommendations for cam, springs, lifters, and rockers?

Thanks in advance for any help!

Thanks for the info!

Do you have retainers for the beehives that you could possibly part with as well?

Ah yes I forgot to mention that I'm using the stock converter. I don't have to worry about emissions/inspections though.

I'll give LE a call too.

Just talked to LE, he recommended:

218/224 with .570 lift (if using beehives) with 1.6 rockers and my aluminum F-Body heads. He said stock 561s are just about an even trade for irons as increased compression makes up for the slightly lower flow.

94MI9C1, PM sent regarding the springs!
