I am picking up a '69 428 HO this weekend (to rebuild) and I have been looking for pistons. All I can find are Hypereurectic. Does anyone make forged pistons w/o having to get custom pistons made?
Would the Hypereurectic pistons hold up to NOS or should I keep looking for forged?

Scott, does Summit stock these? I did a search and didn't see anything that was stocked for a 428. Jeg's had the SRP but not for a 428.

SRPs or Ross, only way to go! Venolia will make them as well.
The off the shelf SRPs are +.065" and are by far the best buy on the market for 428s. Call P'dude or KRE for the same.   SECOND AMENDMENT: AMERICA'S ORIGINAL HOMELAND SECURITY. I Misus Rash'!

If the block was already .030 I wouldn't mind getting the SRP's but I don't want to go that much. I would like to be able to go just .030 the first time around. I have contacted Paul Spotts and he can get me the TRW's.

There is no more TRW. Hasn't been for many years. And Sealed Power/Speed Pro quit making the "Forged" one over 5 years ago.
Yes SRP makes them and I have run them in my 76 T/A with over 400Hp of spray and rpm's in the 7600 range for many seasons. 9.40's @ 146. Yes they are a good piston. I run what I sell and sell what I run.  How many other Pontiac builders can claim that!!!!  Build it fast, build it right, build a Pontiac. http://PontiacDude.cc |

Damn!! I hate to go .065 over on a standard bore block, but I have been hearing good reports on the SRP's. I have to make a call to Larry Hansen, here in NJ, he will be doing the machine work.
Thanx, everybody, for all the input.

I had custom Ross pistons made for my engine and they did not cost a whole lot more than off the shelf SRP's. That included pin fitting for floaters.

Only name for custom pistons you need to know from now on is CP.
Makes the Ross' look like dirt.  Chance favors the prepared mind. |

Well the 428 deal went sour!!
 Dude, this one is for you!! Could a 428 crank be cut down to put into a 400 block? Or would a SCAT/CAT/Eagle/whatever crank be preferred? I may be able to get a 428 crank.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
