Introducing..Summit Pro LS Forged Pistons!!!!!
Ok, for some reason I thought you lived in Texas, sorry about that. I do most of my own work also just because of the cost to pay someone else. If money wasn’t a factor I’d let better people build it for me. I will say this RPM trans has been money well spent. I know nothing about transmission building and I love this thing.
thats why why I learned to build my own transmissions. Someone else isn’t going to pay attention to details on my trans like I will. And my attention to detail is also applied to other people’s trans I build because I take pride in what I do. And I care.
[QUOTE=Summitracing;20041672]I would consider a 4.085 bore but prefer 4.095 ..., yeah I know they are odd sizes and your probably not going to build them because they are not as popular. I'd also like to see a LS1 piston 20 over !
I disagree. I have to ship my stuff off because the places around here are hack jobs. Been there, done that. Having to ship a rotating assembly will be very costly on top of the fee to have it balanced. so yes, having drop in pistons would be very nice. Having an option to throw a set of forged pistons in a 5.3 budget build without having to have additional machine work done, would make sense. No matter what you think, alot of people dont want to have to send a rotating asembly to the machine shop and wait. I remember having to wait a month or more to get my stuff back. Sorry, but that doesnt interest me. I'm at the point to where either i'd buy a complete rotating assembly thats balanced already, or just leave it stock and not mess with it vs having to pay $300-$500 for a balance job. Eff that. Drop in pistons just make much more sense to me, would save lots of people, lots of money.
It's always so easy for someone on the internet to spend someone else's money too.

Ive had 3 different low ten second street cars and zero transmission issues with any of them. Two of those were heavy GTOs. I’ve used FLT and RPM Transmissions and wouldn’t hesitate to recommend or use either of them again.

Awesome job, Summit Racing! Super high compression pistons are the things of dreams, and beyond the realm of practical application, for most folks. The ROI seems low for a volume sales retailer.
Just placed an unrelated international order with you folks yesterday, and seems that you have got a grip on that aspect of your business too.

Yes, we built the .945 pin "gen. 3" pistons with circlip grooves for people doing what you're doing. You will have to order the clips separately. The reason we left the clips out of the packing was trying to keep someone from accidentally trying to press fit AND put clips in. That could be disastrous of course, so we try and eliminate the chance of error that way. Clip part number would be JEP-945-073-MW
Glad to see that these can be used with gen 4 or aftermarket floating type .94x" rods then. I'd just include the clips with a warning for dumb people lol. Weights will be nice to have also.

It's funny. We actually do have a warning written into the instructions. The problem is the people that would make this error and the ones who wouldn't read the instructions. I'll work on getting those weights to you.
I'm thinking you would have a lot of takers if you just offer the ls1 sizes in both pin bores as you do with the 4.8/5.3 stuff.

We think you're right. We'll put that on the to do list. Thank you for the suggestion.

Agreed. We do have design weights for some of the piston models (but not all bore sizes of each) and have confirmed they are close to actual pistons. We have a project underway to measure each piston by bore size over the next few months. When we complete the project, we will be adding a note to the listing with an "average" weight so people can get an idea of their bobweights. At the same time, we always want customers to have the pistons in hand when balancing in case there's a variance of a few grams. If you have a part number in mind, please PM us and we'll get you what we've recorded so far or go out and measure a set for you. Thank you for your interest.

Hello, sorry for the delay. They will be absolutely fine with that power level. We do recommend upgrading the pins to the S718 .927x2.250x.200 wall pins at 300hp nitrous as it puts a serious force on the pins if engaged around torque peak or lower.

A nice lineup of L92 and LS3 parts is in the works, but not currently available. We'll make an announcement when they are ready. Thanks!
I'd rather not have to add 100 grams of heavy metal to balance. I'd rather spend more on pistons and have to remove weight from the crank, then add a bunch.
I'd be a buyer if they are what I'm looking for.
Yup... It seems like the high dollar pistons always list an average weight, but cheaper ($400-500) ones do not. I'd really like to see the weights for a 6.0 based motor, as I'm building one currently.
