New oil pump
ARP bults all the way thru

BUT now to the question

Am I stupid to reuse the EBU rods???? or should I ad $329 for a set of mummert I beam rods??

It will go in a F100 and be a daily driver thing that occationally wants to repaint the asphalt black....... No strip or that kind of things.

I just want a y block with good grunt .......... Or would I need some beefier rods despite the mild cam???

Thanks in advance
