Need some quick answers on this one.
The problem is that I need live in sweden and need pistons for my engine NOW (read "like today").
You don't want to hear the whole story but I can get KB:s forged IC782-060 with rings and the speed-pro ZL2465F60 with rings shipped today for a total cost difference about $325 (with shipping costs and taxes in my country).
Far as I know the downside of the speed-pro is the weight?
If I choose speed-pro, how much will I loose of that choice?
So wich pistons would you buy if you were me and the pistons is going to be in an 454 bored 0.060 over, 049 heads with bigger valves and ported, xe284-10 cam, holley 870 and so on... no NOS.
And ooooh, I'm on a tight budget
Thanks for quick answers!
