Internals

Anyone know of any good tech articles I can read up on about replacing the internals of my '03 4.6L sohc? One of the places I keep finding to buy parts is from Sean Hyland. Theres a complete 4.6L Rotating Assembly and the same kit in a Stroker Version. I do know what it is meant by the stroker kit. I had a stroker setup in a outlaw shifter kart class I use to race in. Is the stroker worth the extra 500 and is there any disadvantages or things to be weary of? I am keeping this car my DD, but I figure beefing parts up shouldn't hurt much. Anyone know if Sean Hyland is reputable?

And anyone know if flat toped or dished performe better, in general, for these motors?

RE: Internals

SHM is a good shop BUT their customer service really sucks!!! I won't do business with them anymore...once they get your money they forget about you until its convenient for them to remember.

A much better shop and former employees of SHM are the guys at www.vtengines.com

If its a DD then Flat top pistons aren't what you want since that will boost your compression over 11/1 and require race fuel....
stick with the stock 17cc dished pistons if you rebuild as thats a perfect CR for NA and Boosted applications on 4.6's.
