MRL Performance 340, WOW!
Do you think I could get those numbers with those heads alone or would I also have to get a roller cam ? Now I have 398 HP @5700 412 TQ @4300 Stock 340 J heads with mild porting and Mahle 10.5-1 forged pistons not sure the cam as it's changed a few times , hyd close to voodoo 10200703
- Advertised Duration (Int/Exh): 268/276
- Duration @ .050 (Int/Exh): 226/234
- Gross Valve Lift (Int/Exh): .494/.513
- LSA/ICL: 110/106
You think it's possible to get another 80 HP and 45 TQ with the heads and a streetable hyd cam , or would it need a roller cam as well to keep good reliable street manners .
Thanks
