Roller lifters: Hyd or Mech?

[Old Guy with 87 GT]

high rpms were kinda the point i was going for

hydrolics are fine and still very functional up to 6,000 rpms......unless your future plans for the moter are for 7,000 rpms or higher ,then go with hydrolics

in order to build a moter that'll spin at 7,000 plus there's other issues you'll have to deal with aside from the lifters .....the moters balance ,the ingnition system ,valve springs ,ect

i have a friend who recently rebuilt his 92 moter(306 now)....he reused his origanal hydrolic rollers that had 130,000 miles on them ,when his moter was built he had it balaced to 7,000 rpms and he just recently got a custom chip with a higher rev .......he hasn't had any problems with them yet and he's been redlining it to 6,800 rpms

my hydrolic roller lifters have over 200,000 miles on them ,and my car doesn't have any problem finding the 6,200 rpm rev limiter it has .......hell... i had to buy a shift light so i don't hit the rev limiter by accident agian
