Ams spec ross..... it's 319 or 349... lol i don't remember. They havethe light taper wall pins I'llhave to look at my sheets that ccame withem.....

 

those pistons will weigh 375 or more.

 

348.7 with a variance between the set of 1 gram. If you want me to take a picture of the paperwork I will.

 

dont toot your horn . 348 is still a very heavy piston for an aluminum rod setup. dumb if you ask me. and those tapered wall pins are rated for 100hp per hole big guy. there gonna flex like crazy with just 400tq. but have at it. I dont really care what you do or how you do it.

 

I didn't toot my horn. 348 is heavy but for a full skirt piston it's good. like I said all this was to do was replace the stock internals and let her eat. If it blows it blows and I'm out 500. The 2.1 is on deck. If it doesn't let loose then I'll run it for a while swap the 2.1 in when the shootout comes and then do a better piston rebuild on this 2.0 so i have a backup motor on deck at all times.

 

Btw 100 per cylinder? You sure about that?

 

very sure. most shelf stock pistons are supplied with a lightweight .150 wall pin. stock evo 8 pins are .240 thick. material doesnt matter. it needs to be thick to minimize pin flex.

 

I just updated my last reply from 2012. Here are pics of the Carnage from installed errors on flywheel bolts.

 

who installed those anyway. i dont see any red loctite either.

 

^ The Idiot I purchased car from.... Correct, there was no traces of loc tite. If you read my previous post prior to the issue, it was a well built set-up assembled by a Moron. It's my problem now, I'm in process of buying replacement crank & doing further cyl head improvements. But wanted to update, due to Aluminum rods. Im on the fence about keeping them in, I believe I will, just concerned about life expectancy with Street driving & Heat cycling.

 

John Bradley,

How many miles do you have now on that motor w alum rods & no oil cooler?

 

That motor is sitting in the old white drag car and hasnt been run in awhile...it was 25k or so when it got pulled out of Luke's and went into that. We do recommend a big oil cooler setup on them though, Our 8.5x11 oil cooler kit is plenty.

 

Nice! Wow thats big. Will it affect the oil pressure??? Do you sell it at your website? I was just going to make my own using B&M. I thought it's already big enough lol

Doesnt affect oil pressure, it is $500 for the kit. I am not sure if its on the store but I know its no more than a phone call away.

 

So everyone who posted 3-5 years ago...how are your al rods/bearings doing these days?
