Re: xe258hr less than 10k miles , and roller block 5.7

Im a noob at this so I was wondering if alot of tunning is needed for that cam....is it more for racing or street use? what kind of increase in hp/tq?...will it affect gas mileage much(not too important but its nice to know)?

Re: xe258hr less than 10k miles , and roller block 5.7

the heads would need the valve guides milled down at a machine shop for the added lift.....anything over .470 needs to be.... its one of the best cams you can get for a 305 tpi.... I actually traded this cam and block for some nib subframe connectors,,, I believe the member I traded with decided to go another route and is now selling this cam.... look for his add with the xe258hr in the title... hes a good guy.
