i have a 1985 irocz with a 305 thinking about putting a 383 i'm wondering about the holley stealth ram upgade to tpi. in the summit catalog the stealth ram is only listed from 1989 to 1992 im wondering why it is not listed to 1985 any help? also any tips from someone that has done this before would be greatly appreciated thanks. adam

 

click the "search" key. Look under Holley Stealthram. You'll find more info that way than you will by posting. - If you car still has the 85 ECM(computer) look into upgrading to a 89' computer(slight wiring mods required) That'll solve A LOT of problems you'll have HSR or otherwise...

 

ok thanks alot i will try that
