Re: le1.5 set up

Is it the LE2 heads with LE1 cam or vice versa? The more the heads are ported the more you'll get from the intake and TB. Did you port the intake runners until they broke through and then welded them back? That's really the only way to get any noticible gains from the stock intake from what I've heard. I'd say a little more peak hp and a little less low end for the LT's, but they say that you get more area under the curve, which is what you want more than anything. Get it on the dyno and let us know, then post track times, since that's what REALLY matters.

Don't think the TB will help any, in fact many people have had more problems with them than they're worth, except for AS&M. I'm sure Lloyd did your intake right. He knows his setup better than anyone, what did he tell you to expect?

Re: le1.5 set up

The LT's will help the most over your midlengths. The ported intake is worth about 8-10 peak a little under the curve. The TB probably won't help a bunch but it will help. You can't really over TB a LT1 intake cause it's pluemn volume is so anemic. I say that you will be right around 390-395 and with the LT's it will feel smoother on the low end cause of the better scanvaging, plus that's what the cam is designed for.

Re: le1.5 set up

changing all of that at once should get you 390-400 RWHP as long as it is tuned for the changes.
