Re: whats a good piston for a 69 302

Mine was done with Federal Mogul pistons before I bought the car. I can't say whats good or bad but I was told the builder was known for high quality work.

Smile Re: whats a good piston for a 69 302

I'm not even sure we can still buy stock 302 pistons anymore so please consider ROSS or one of the other name brand custom piston makers.

And I need a 4.00" set myself unless I go w/ 6.25" long SJ rods and 6" rod 350+.030" over flat-top pistons and small chambered heads!

And I WILL NOT install hypers in a 302!! Period!

Cheap steel-strutted cast or forged ONLY!!

Re: whats a good piston for a 69 302

I used Wiseco. They make .03, .04 and .06 over size as I remember. The dome is not exactly like the originals but they are forged. I got mine from Summit.

Re: whats a good piston for a 69 302

I would compare the price of a Brand Name Piston such as ROSS to running a TRW Speed Pro 350 Piston with longer rods. The 350 piston is lighter with a better ring placement.

Re: whats a good piston for a 69 302

I've always heard that TRW's are heavy. As compared to what? Are they heavier than stock?
Thanks

Re: whats a good piston for a 69 302

Factory stock 302 pistons were TRW supplied... back in the day, sealed power had a duplicate piston. I'm not sure now. I've got Forgedtrue in mine (simply because I owned a set of forged 30 over pistons when I rebuilt mine). If you are at stock 4" bore size, find someone with a good set of used factory pistons (I'm keeping mine though) .. )

Whichever you choose, choose FORGED.. not cast, not hypereutectic....
