Hi guys, I've posted this in the Nailhead section but , it seems, can help. I need your collective wistom here. In a year or two I will be getting my 425 rebuilt. Iwant to get as much power as I can out of her(headwork , headers) and hopefully the best of everything. I know you can stroke a 425 with 364(?) rods. What displacement , h.p., torque can generally be had? Exactly what machine work and costs are involved and so on. Pro's and con's? Wadda ya think? Thanx in advanceo No:
Well? I can't say I have any experience with the Nailhead motor but I know the head don't breath well. More cubes just means it will runout of breath sooner unless your looking for just off idle grunt. The no replacing air flow. If your looking for power, look for areas to increase air flow, thats where you'll find you'll make you biggest power increases. So if it were my money, I'd put it toward some good port work instead of more cubes. Good Luck.
Thanx for the replyp . It seems everyone is trying to talk me out of stroking. I DO intend to send the heads to Mr. weise or Mr. Burek:blast:
