Ta block build . Solid lifter on hydraulic cam profile - spring recommendation.

[1987]

I am almost done building my ta block, ta headed engine. Looking for spring recommendations s for a “street roller”
(Solid roller lifer on hydraulic roller cam)

Thought this may be the place to ask

Heads are ta se , valves are 100 long .
1.6 ta paired rockers and a 22x roller cam , 570 lift.

Anyone happen to have a similar setup and part number for the springs locks and retainers to get me in the ballpark..? What brand valve spring seems to last longest for the street?

Thanks

1-800-TAperformance would be a good place to ask.

yes that is an option, just curious what’s out there ….

PAC 1209X installed at 1.67-1.70 would get you 210-225 closed and up to 510 open..... That might (might) be enough.
Target the advertised open height to keep you away from spring surge. See where you end up on the seat.

On the ta headed cars
Duel springs and 200/500 open
I've spun them to 7500

That’s what I was curious about , the solid lifter , tight lash setups.

lifter weighs less than the hydraulic

Combination is very important
Backpressure compression
Turbo and the list goes on.
I don't know how high you plan on spinning what I do know with the new turbos now we make big power and it comes on really early

I have a little more duration on the cam than you but did the same and it worked extremely well. Hydraulic roller Cam with Crower HiPo solid roller lifters. I used the PAC 1294 valve springs. To highlight others points, combo is extremely important. For a street application you want the lash on the tight side, otherwise it will beat the crap out of the valve train. ****MUST**** recheck valve lash hot after everything brakes in. That will make a difference, I promise you
