302 pistons
 
Anyone have a source for a set of 302 30 thousand over pistons. Looking for forged but has anyone used the hypertch one Rickssells?

I would use forged for the correct sound. Wiseco makes a pretty good set.

Thanks I was looking for TRWs but cannot locate a set of them https://www.yenko.net/ubbthreads/imag...ins/3gears.gif

I used these in a 302 I built for a customer a while back.

Hope that helps.

I would call Camaro Hi-Performance. I know from talking to Randy Wells they build more 302's than anyone. I know someone who used the NHRA J&E forged aluminum pistons. Just like the oem GM. Very happy. Heard horror stories about the silicone cast aluminum pistons that Rick's sells. One guy's engine locked up on the dyno due to wrist pin issues.

[/ QUOTE ]I believe you have to fly cut the TRW's. I have TRW's in mine (30 over)and they only came with the bigger 12 to 1 dome.

TRW's have the thin rings too. Not the best for a street Z28. Been down that road many years ago.

Re: 302 pistons
 
Right about the thin rings. Got along so far with them but the car only gets driven 1 to 2X a week. So far so good!

I received an email from Jerry MacNiesh and he uses JE pistons. I will call them tomorrow and see what they have

Re: 302 pistons
 
When I built my 302, years ago, TRW was all that was out there. I had .200 taken of the domes to make them 11 to 1. I also had the ring lands opened for stock rings. Wasn't building a race motor. Was looking for long life....Joe

Re: 302 pistons
 
Yes I am looking for some reliability out of this motor.It might see 5000 RPM but thats about all.

Re: 302 pistons
 
I've barried the tach on mine after balancing. With 4.56 gears, it doesn't take long to get there.....Joe

Re: 302 pistons
 
The car has the CE engine in it now and with 3:73 gears it may have seen 6000 rpm. I am not sure if the CE motors were balanced from GM or not.

Salvatore 12-14-2009 09:19 PM

Re: 302 pistons
 
Crate motors and original motors were all the same back then I believe. Don't know if any were really "balanced" like a machine shop would do. When we bought crate motors we took them apart to check clearances more than anything back in those days.

Re: 302 pistons
 
Made a couple of calls. The J&E are the way to go. Exactly like the original GM and approved by NHRA for Stock Eliminator. No machining, no nothing, balance and install and you have exactly what the engine should have.
