I'm putting together an LQ9 shortblock with l92 heads, vic jr carb intake and leaning towards the Comp 285LLR cam on a 113 lsa and had a couple of question. I realize the pistons will need to be flycut, is there enough material in the face of the piston to flycut for this arrangement without getting too thin? Also does this sound like a good cam for this setup? It's going in a 2800 drag car with a th350, 4.56 gears and a 29in tire. Thanks for any help,

Darren

I dont think you're going to want to use that cam with those heads. L92's are not regular LS1 heads.

Why not? That's a cam that comp reccommends for use with the L92 heads.

anyone? Also would you reccommend running a tighter lsa since it will be carbed and I don't have to worry about efi tuning and driveabillity?

Heres an article with dyno testing on a bunch of cams, they wanted to do the 285LR but it had PTV issues so they couldnt run it. They ran one slightly smaller(277LR) and made 550hp with a carb on a 6.0L w/ LS3 heads, which are L92 heads with the lightweight intake valves.

Thanks for the reply. Funny you posted that link, that's the article that got me started on this project Well, that along with Dave's 9sec red lx hatch on here. Not caring about street manners and running a carb I feel I could benefit from getting pretty aggressive with the cam. Do those numbers look on track with similar builds, or have others seen better results with different cams?

Pretty close to my 6.0/L92 headed build. I'm running a 238/250 cam w/ 113+3. I flycut the pistons since the heads are milled. I don't know about the stock pistons making the flycut. Mine are Diamonds. The cam itself should be good for that build w/ that usage in mind.
