cam selection

ok, well before i call a cam company i want peoples opinions. my set up will be

L98 bored atleast .040 over (maybe more if i have to, blew it up not sure what damage i have) stock heads, holley stealth ram, good exhaust system. ive been playing with the idea of a stroker motor, but im not sure i want to dump that money into it. the springs on the heads are good for up to .550 lift, and ill be using the stock 1.5 rockers.

i put the LT4 hot cam in and then less than 20 miles later i sent a rod out the oil pan, so im gonna rebuild it and i may go ahead and put something bigger in. i dont want really want to go more than .550 lift (may make exceptions) and i dont want to go less than a 112 lobe seperation.

any ideas?

Re: cam selection

I was going to suggest the very cam you already have. If you want to wake things up I'd look into a better set of heads than stock before you think about going any bigger on the cam.

The Hot cam was designed to use 1.6 rockers to achieve it's full .525" lift so...... well, I guess you see where I'm going with this.

Re: cam selection

too big of a cam can be useless without proper tuning,
pick a cam that works with the HSR power band
peak power under 6000rpm, and it starts to really level off at about 5500rpm
