Default New rods for our pontiac

Looks like Butler Performance got EAGLE to make a 5140 factory replacement forged rods ( with arp 7/16 rod bolts ) at 319 dollars. There press pin only. Wish they would offer a bushing type also. sitehttps://butlerperformance.com/i-31643273-eagle-5140-forged-i-beam-rod-6-625-2-250-pontiac-rj.html

As far as I know he is, but pretty tight lip on rest of the build.

The forged PVC rods are easier to put back together after they break

as you know I don't like Chinese made anything. the 2.200/.990 Chinese rods were a PITA. you had to buy the pistons too, so they'd fit and work in a Pontiac engine, and also cut down the crank, and if it's a factory GM crank that will never fit a Pontiac rod again, it's ruined. bastardized. Chinese-Chevy-ized.... or buy the Chinese crank. holy shiit too much work and expense already, then when you're done you can't give that stuff away, cuz it won't fit anything unless you put the entire Chinese rotator in. well maybe you can sell it to new generation X racers who are 20 years old and think a 1981 Trans Am with a 403 was the meanest Pontiac ever made, and had a real Pontiac engine....(one of those kids offered me $4000 for my RA V Firebird, and bragged to me with pics of his late model TA that looked like a Christmas Tree that somebody went nuts on with a credit card buying mags and stuff online) now imagine those Chinese crank, rods, and pistons in a $60,000 1970 restored Trans Am. Suddenly it's worth around $30,000 cuz it all has to come out and get replaced with vintage GM stuff. or it doesn't even get any bids at Barrett Jackson... This Chinese stuff is basically racer-only filler, then throw it away, give it away, or blow it up and get another block, to fill it with new Chinese stuff.

ok maybe the pistons are made here in USA ....but you get my drift

but at least now they make the rods that fit a Pontiac as is. good move. great price. too bad they couldn't make them in USA. then it would be FIVE STARS, WIN-WIN situation.

going with Chinese stuff with Chevy dimensions just so you can run a cheaper Chevy piston and rod bearing and rings, is like going to hell to light a cigarette. I like the Butlers, their cars are fast, but I think long term you can't go wrong marketing the standard dimensioned Pontiac stuff. FORGET about what it can run at the track. RA V heads are worth more than any resale, they don't run the quickest at the track anymore. wanna repop the Pontiac stuff ?? make it EXACTLY like the original stuff, warts and all. it will sell better, believe me....even if it's slower. if you took a RA V head, intake, headers and cast it EXACTLY like stock, in cast iron or aluminum, it would outsell everything. but they just don't get that...yet....

this rod is a step in the right direction. but it needs to be made here in USA, cuz we're now in a trade war with China. it may turn into a hot war. if it does, forgettabout buying Chinese made anything. it's already getting the balls tariffed off it by Trump, which is why the rods started at $319, and now they're $349. they got hit with a 10% tariff no doubt.

only a very small percentage of Pontiac owners are all out diehard fast racers. 99% of the Pontiac market is street cars with stock stuff. yet the Pontiac vendors cater to the 1%.

what made Chevy bigger than all the rest of GM, Chrysler, and Ford put together ?? they catered to the 99%

Charlie,the issue these days is getting a affordable forged crank.Virtually all 3in main forged cranks require a BBC rod.Im building another RA V engine and wanted a 4in stroke crank.Im going to use a Scat forged crank and Molnar 6.6350 rods which depending on the deck height of the block I can use a stock 428 piston.IF I was going to build a MAX effort pontiac I would use US made crank and rods but for a hipo street engine it makes no sense IMO.Tom

I've only used one steel 4" Scat crank for the Pontiac, so I don't know off the top of my head, but I would check to make sure the piston pin boss will clear the counterweights with that short of a rod.

If not, you're gonna have to have some lathe work done, which could possibly entail some more heavy metal to balance. All-in-all, it may be cheaper for you to use a longer rod with a custom piston.

I used a 7.100" rod in the last 434 that I did with a 4" Scat crank.

Zero I’m with you I hope trump using tariffs on steel and alum can bring back all kinds of manufacturing including performance parts. Just a note on the rod this is not a butler only deal, it will be sold threw summit jegs etc etc and yes will find there way onto ebay. Also eagle rates them at 750 hp. I would never run them at that horsepower but 500-600. Last comment price point is important $349 press pin and higher makes you look at the 4340 bushing h beams for a couple dollars more

A friend has built a few engines with the Scat 4in with the 6.6350 rod with no issue.I REALLY wanted to run the 6.350 but was told by Scat what you just said.Im not a fan of long rods,just me.One thing that gives me thought is there is NO country of origin on these cranks.I know Scat does custom forged cranks from their offshore forging and also does billet cranks with material from either UK or Canada.Maybe Tom would share with a direct customer IF the entry level forged crank is 100 percent machined in US.Being in SoCal I kind of doubt it.Tom

I'm direct with them, maybe I can find out.

With the sheer amount of items having some kind of offshore "touch" to them, I simply can't be biased that way.

Everyone has their preferences though and I understand that. I personally wouldn't run an Eagle product in my lawnmower and haven't used anything from them in some 16 years. FWIW, I run a ton of Scat stuff though and to my remembrance, I've only had to send one Scat crank to the crank grinder to be "touched up". Most of the time they come in with less than a .0002-.0003" tolerance, pretty similar to what I've seen from Callies.

I have seen a Scat cast crankshaft crack, but it was in a 540 hp bracket engine for 8 years straight, with repeated 5500 rpm clutch drops and 7000 rpm shift points.

I'm not a heavy piston fan, so I use a "moderately" sized connecting rod length. I don't like them so long that the pistons are unstable either. I have used a 1.040" piston and there was lots of rock. Something around the 1.2-1.4" mark is very stable though and takes a lot of weight off of the rod, especially at higher rpms.

Just my two pennies.

BTW, Molnar is also not made in the US, which really surprised me. VERY high quality pieces.....

Molnar does not make the 4in stroke so that why I went with the Scat,Scat does not make the 6.6350 so went to Molnar.From the pieces I have actually seen with my own eyes the Molnar seemed better finished.After research,the consensus is Scat and Molnar are said to be finished here in the US but im hard pressed to believe on the entry level stuff.I have never used any Eagle but have used a couple Ohio cranks with no issue.Tom
