I went with JE because I thought the price was pretty good. Like I said they are "nitrous pistons" and I paid $1030 for the pistons & rings and that included shipping. I don't now what the Probes cost so I can't say anything their prices.

It is good to hear that all of you had good luck with our pistons. We are looking at ways to lower cost without sacrificing quality.

My 632 runs JE nitrous pistons. Two seasons with no probs. Running 700 hp nitrous, twin 1220 carbs.

So I guess your all saying no funny gas for my 496 as I have the soso srp's. Dang it! :evil:

If you decide to upgrade call Titan Motorsports and ask for "Bottle" tell him I told you to call. They are a distributor for all kind of performance companies. Their web site is www.titanmotorsports.com

ARUSSELL, the JE tech said it himself a couple months ago, he does not recommend useing nitrous with SRP pistons.

Zip.

Our SRP parts are designed for about 100hp per cylinder, or for most of us 800hp. If the engine makes 650, then 150 nitrous is safe.

some 1 would not sell me srp for a blown 1471/572 chevy alky motor dart 360 heads all the good stuff would they?

I wouldn't say that some people will sell anything just to get the dollar, but it would be one big mistake to put them in a blown alcohol motor. I've got 7 of them setting on my shelf in the shop that came out of my 358, 1471 blown alcohol sm/blk, the 8th one melted right down to the top ring groove about a 1/2" wide blowing out 3 qts. of oil and spinning a rod bearing, it happened all in 1 pass and there was less than 10 passes on the motor.
Best to go the extra bucks and buy blower or nitrous pistons, the top ring groove is down 7/16" from the top of the pistons on them.
