Replacement Pistons

I need a set of .30 over pistons for a HIPO engine. Anyone know where the best place is to purchase them?

Thanks for your help,

Gary

Contact Sealed Power use the replacement pistons for 1987 thru 1989 Mustang H.O. forged units. The balance weight is very close and they use a very tight cylinder wall clearance. You can find them used in great condition for pennys. If you block is standard you can have them coated and save you block or buy new ones and have them coated . You should check your block first of all.They are press fit and have flat tops with four eyebrows ,which will give you the same compression. I hope this helps. Ron

The part number you want is L-2482 TRW number which Sealed Power owns. I have one on ebay for sale check it out. Just search for sellers at the top bar advanced search. mr.ford-4969 is my seller name. The piston is flat top and has four eyebrows. Ron

One of the local machine shops I use highly recommends the sealed power pistons.

You don't want the L-2482F piston as that's the wrong piston for 289.That piston is for a 302 and the wrist pin location is wrong and rod center line is different on the 302.

Bob,

So the info on page 12 of Tony's book is wrong?

Thanks,

Gary

I am unfamiliar with TRW numbers however a 289 and 302, except Boss 302, use the same piston. The difference in the stroke is made up by the shorter rod on the standard 302. Ford did not relocate the pin hole on a standard 302.

Gary, the answer to your question is that Tony's book is correct and you have the right Pistons.

Thanks Marv.... I was sure that it was. I just wanted Bob to think about his statement and correct it so future readers know the correct piston to buy and that Tony's book is correct.
