On the springs, makes sense. cool

TE72_Turbo
What symptoms pointed you to 'tired valvesprings' ? Did the power fall off sharply.... valvetrain got noisy in high rpms ?
what 267 cams do you run ? Did you notice a considerable gain ?
Did you have to change lifters or reshim ?

I'm not looking to make a hi revver. There is enough rpm range for a decent powerband for a street car imo. I'm curious about what a cam and valvegear costs vs the performance yield.
My plan is to throw ~20-24psi of "small" t3/t4 at a stock 4age. Looking for ~320whp and ~300 ft-lbs tq. Should give a hard accelerating midrange, as opposed to a more peaky tq curve and extended rpm range.

Next project is a ca18 sprinter, that I'm sure can go silly quick with the same approach. Perhaps +40whp/tq more. Got ~$600usd into that drivetrain and swaps r ez 4 me, so its kinda hard to justify throwing money at 4ag valvegear mods.
A turbo 7ag might make an interesting comparison.
