How much pressure can stock 62 pph injectors take?
A friend of mine is putting a 383 in his Astro and were figuring out if he should buy 90 pph's or bump the fuel pressure up on the 62 pph's.
I figure the 62 pph's will need 22 psi to feed it.
Will they handle 22 psi?

They should handle it but for how long, I don't know. The more pressure the harder on the injectors and ecm but I think it's worth it since the spray is almost always better.
I'd stay around 15-18psi max, anymore and it's on borrowed time although many of the guys on the diy-efi lists have had great success with higher fuel pressure...just don't do it with the older style holley injectors!
