Thanks for teaching us some details

[@autovationFtWorth]

Any time, my pleasure. Hope you enjoyed

This is the info I was looking for. My trucks motor needed a whole bottom end replacement so I decided to make a 408 stroker since I found a forged 4 inch stroke crank locally. Was looking at the 6.125 rods with the summit pistons for the stroker because they're by far the best pricing I've found for them. Now I can feel better about ordering them. Thank you

[@autovationFtWorth]

I'm glad it helped. I bought them without knowing but the Arlington store is only a 30 minute drive away and I could return them.

I assembled a stock bore and uncut deck lm7 type from a 4.8 pullout using k1 forged crank for 5.3 (Didn't want to go high on stroke to preserve the walls and the pistons and also maintain as much material on top of piston), used maxspeedingrods h-beams with a 6.25 SBC length, and summit pro pistons I believe 1800-3780. Had it all balanced for like 250. Ported 862s and twin china 76s at 29lbs on pump 85 shifting at 8200 rpm. The summit stuff is good enough for me and the car makes over 200 HP per liter. Entire engine was under 2k total. I did blow out a head gasket and torch a hole through one of the heads when the head lifted/warped. I've since been using fire ring gaskets on stock 61cc chamber heads.

Yup most of the Summit stuff are great quality parts. None of it made by Summit, just food brands in Summit boxes,

very good video man. a lot of knowledge from you. you’d be someone i’d want to learn under for sure. i’ve been a mechanic for 5 years now i’m only 24 but if i could learn from someone from the start it’d be you for sure.

[@autovationFtWorth]

Those are kind words, thank you! There's no secret to the knowledge. I read constantly and have always looked for knowledge wherever I could find it. Stick with it and strive to be the best. 30 years in the business, now 51 years old I hope I know a few things by now.

For those who may not know how re-branding works which I got into researching. We all know Napa, Walmart (Super Tech), even Amazon don't have oil refineries yet have their own oil. Summit's case the factories want to work at 100% or close to it. Most of the time the "name" brands can't keep them busy so they sell re-brands of very similar parts. Harbor Freight Jacks are made in the same factory as Snap ons, hence the law suits etc. China will make anything they can at the price point you want and they can make quality products, just less profits. I also have had no more issues with summits stuff compared. My only complaint over the years is some of the bolt kits are trash when you go cheap. Otherwise I agree, zero quality issues outside of hardware store not even grade 5 bolt kits.

[@umakemerandy3669]

Thanks for the vid. The summit assemblies are pretty attractive for a low cost upgrade it seems. Plus they have them laid out in a way thats perfect for picking what you want on summits site. Wish all the manufacturers assemblies were described thay way.

[@autovationFtWorth]

Glad you liked it. I still haven't installed thos engine so we will see how the parts perform.

[@wtfobiden]

You can be the bob ross of engine building

[@autovationFtWorth]

Happy little pistons.

[@andrefigueroa9297]

You had the whole rotating assembly balanced or just the crank?

[@autovationFtWorth]

The crankshaft is balanced to the rest of the rotation assembly. Crank, rods, pistons, rings, bearings, flexplate and balancer all go to the machine shop and are balanced together. Thus set up required quite a bit of material to he removed from the crankshaft because it was pretty light compared to stock

[@dustinbailey9946]

Well it's been a year how are they holding up?

[@autovationFtWorth]

So far good. Build video coming soon that will detail what this one went into. Subscribe to stay tuned in!!

[@timweb1510]

How are these? Was considering the summit pro ls setup for a 5.3. I thought the rods were made by k1 for those

[@autovationFtWorth]

I haven't installed the engine yet so no feedback. The H beam rods are made by K1, the I beam that I used are made by Scat. Both are good parts manufacturers. I did a lot of price comparison and couldn't find better pricing.

[@timweb1510]

@@autovationFtWorthheck yea man, always good to save money

[@CULT539]

They don’t balance worth a crap. That’s the problem with those. Rods and pistons on a stock crank are even harder to balance. That’s why summit won’t offer a balanced kit. Spend another $500 and get good products. That’s just garbage.

[@autovationFtWorth]

My machinist had no problem balancing this set up. They were much lighter than stock gen iv parts so no heavy metal needed on the crank. UEM and Scat aren't top of the line but they are far from garbage.
