I couldn't imagine the anxiety of dropping a valve with the gargantuan valve spring pressure of that thing yikes!

Early abody had the worst design for the coupler, my dad ended up in a ditch last year because that garbage fell apart.

Did 2 ujoint conversions and one new style bearing I and my dad will never use the stock sloppy junk again and header clearance is so much better.

Did you use a quality sensor or a Chinese cheapo?

Not fast enough! Lol 12.42@108

If my 440 block is good I'm building a 440 or stroker for next year with more compression, bigger cam and porting the heads so it'll lift the tires and be faster.

Plan this year is a 4.30 gear to get better 60ft but it'll probably come up even more.

.030" over 413 about 9 5.1 stealth unported heads 230°@.050" .480" cam 750qft q-series carb, performer rpm intake Shumacher headers. 4,200 stall 727 3.73 8 3/4 . Suspension is ss springs clamped front segment no rear clamps, comp engineering rear shocks set on 3rd click and 90/10 calvert front...

Lifts both tires on this pass but unloads suspension and spun, still beat the charger.

:lol:

Yeah that's expensive for shipping.

I don't have a small block, calm down killer spring will be here soon enough.

I'm skeptical

I just posted that on Facebook.

I use cutouts about halfway down the exhaust and sounds better than off collector.

And don't confuse them with shorty headers those are no better than manifolds imo.

A lot more! comparable to 1 7/8 full length until 500hp and great torque through midrange.yes it's worth it if you ever learned how the tri-y works it's weird compared to conventional headers and yes full length with a 3" collector is better suited for higher rpm and hp applications but until...

Torque!

Tri-y works well and fit better than and full length big tube headers but yeah they're not a high rpm header but most big blocks peak well under 6,000 rpm and unless you take your car to the strip or dyno it it's probably way less than 500hp.

They work better than you think.

Could you share knowledge? Or is it some secret code between old Mopar guy's to not share their understanding of mopar engines with anyone else? Or do we just follow antiquated mopar books from the 70"s?

Why are the engine builder's not commenting on this thread?

I live where the wind hurts my face but the suner has the most beautiful sunsets and weather.

Well and compression.

I've watched his videos at least twice, yeah it's Fords he talks about but they're all air pumps.

No quench, no compression with stock open chamber heads. You could put closed chamber heads that flow better but still low compression and a stock cam that's barely opening the valves.

Why not both? Lol

I did stock 360 heads with a an erson 292 .441" lift on my 74 318 I had and it was a dog anything under 3,000 rpm but would come on strong until the valves floated at 5 grand

I'm thinking small bore challenge 273,318 and 413.
