I tried the search button but everyone has head work with the cam so I can't tell what hp and tq gains people are getting by switching to the LT4 from stock with r.r. If anyone can tell me how much on a full bolt on car or show me a thread or web page it would be greatly appreciated.

Thanks

If i am reading this correctly your asking for hp and tq numbers on a hotcam and 1.6 roller rockers, with stock heads. If so I dont see it being any more than 330 to the rear wheels with full bolt ons and tuning. I had a hotcam and stock head set up, but never dynoed it. Ran 107 at the track for mph with about 3700 pounds including me.

 

I think you're being optimistic with that 330 RWH from just the Hot Cam and RR. I can see 330 RWH if using stock LT4 heads. Otherwise with stock LT1 heads it should be somewhat lower. If you want to get some ideas as to what it will put out look on here:

you can make more than 330 rwhp. My numbers at the bottom is with a mail order tune, hotcam, 1.6 rr, long tubes, slp loudmouth. I'm also running lean, I'm taking it back this weekend for a tune and they told me they could get me at least another 10 hp
