I agree, tri y headers work well. My ls1 put down 420rwhp with 1 &5/8 tri ys, my holden v8 track cars makes 605 flyhwheel hp with 1 &3/4 tri ys and my holden powered street and strip torana makes 450 flywheel hp with 1 &5/8 tri ys, im a fan !
What do you charge to tune a rebuilt ls1 with a cam upgrade with all the goodies to match, has a stall converter etc etc had it tuned by a company and I’m not convinced it’s at its full potential so let me know what I’m looking at?
Love the content could watch these commodore builds allday everyday
Nice work guys can't wait to see my ute i miss it already!!!😂🤘
Love holden caprice😍
Great combo 👍
What brand of Tri Y were on the car? Thanks
Nice result guys
love the tunnels back in.. no more saggy holes hahahah off topic
No no no, tri y’s are so underrated. I have put them on a stock l77 and it rolled off 240 rwkw on e85.

Apparently Nascars use tryYs so if they can use them they must be good.
Great results.
Keep the Ls content coming.
Idle videos would be great to
Also what did you take off the heads?
cheers! Took 30 thou off the heads

Hey mate flick us an email info@onsongperformance.com
Great results there, would you recommend changing the diff gearing for that cam?
Depends on your usage, generally yes we recommend shorter gearing, but if you plan on doing a heap of highway driving it may not be best suited.
What compression is this engine with those heads ?also how many thou is taken off the heads ?
30thou off the heads, I would have to double check compression, but generally end up between 10.5-11:1
Question looking at doing a cam stage 2 maybe a 3 for my l76 but I need to do a dod delete any chance you guys do that ?
Yeh mate we do that
Great content boys
is a stock box and diff fine with that set up?
Depends how it's driven and looked after ultimately. At this kind of power the box will get pretty unhappy if abused
Crows 1215 cam makes the best power
It’s a nice cam, but outdated lobe profile and less lift compared to the 1212.

I like the 1212 better make power earlier and to the same rev range plus way more cam lift.
