can not it be great if I mount a good roller cam then? do you think the dart heads is too much for my engine? if I would go for Aluminum heads then I can keep my cam? with a good result?rfoll wrote:Solid roller springs on a flat tappet cam can mean death to the parts involved, probably too much spring pressure. I really don't know what street driving means in Sweden. The asking price for the Dart combo looks good, but it might not suit your needs. If you are thinking of spending over $1500 on your engine, maybe something else might work better. I woud look at heads with 190 to 200 cc intake volumes. Buying aluminum doesn't guarantee performance. Dart makes excellent iron heads. The previously mentioned RHS will work well also. If shipping is an issue, the aluminum may save enough money to make up for the additional price. If you save money by using your intake, you can buy a carb elsewhere. Keep your cam. Don't get hung up on trying to achive a specific horsepower number.Design a system that will work well in the rpm range you will use on the street. I went from a 350 HP 350 to 450 HP 406 and both engines would spin the tires endlessly on the street, I could barely tell the difference until I put slicks on it at the track. The Comp cams website has a free software download (cam quest) that will allow you to plug in various combinations to see what effect the have on the power curve. It will recommend a cam based on the usage you select.
my cam is mild? or?
I am seeking as much power as possible without changing the base of the engine at the moment.
