I'm about to buy new roller rockers and hooker lt's. I'm wondering what kind of hp gains and track times I could get with this and custom tuneing. Any idea?

 

Im gonna take a stab at this and say 20rwhp or so based on your mods. Unless you have a cam or headwork done tuning wont help all that much.

 

I'd say around 35-40rwhp with those mods and a custom tune.

 

People really under rate the roller rockers. One post on here show a man who added 1.6 roller rockers and dynoed it to the tune of a 26rwhp gain with stock heads and cam. I believe they help more than people think.I would expect a good strong gain from these.
