Noissa minun viimeisissä rautakansissa (C5AE 289 kannet) näpertelyn jälkeen pakovirtauksen suhde noin 85% imuvirtaukseen! Pakosarjoilla saadaan hieman piristettyä kaasujen poistoa, ja sarjojen mallilla ja mitoituksella saadaan erilaisia vääntökäyriä huipputehon kuitenkaan kärsimättä. Eiköhän noissa hieman matalampiviritteisissä koneissa samat lainalaisuudet toimi.Arto65FB kirjoitti: ↑23 Marras 2018, 13:36viewtopic.php?f=33&t=18821&p=147746#p147746

HiPo 289 ja 2/4 V kansien todellinen ero on vain venttiili jousien "taskut" ja HiPo kansissa ruuvi 3/8" studit, normi 289 kansissa (myös 302 ja 351W kansissa) prässätyt 3/8" studit.
Tuossa olisi juuri sinulle sopivat GT40 kannet!Mexico65 kirjoitti: ↑27 Marras 2018, 14:23 Tässä hieman tietoa GT 40 ja GT40P (pekka) kansista, vaikka ovat kovin samanlaiset, niin ei pidä sekoittaa keskenään.

What Are GT40/GT40P Heads?
GT40 heads are a factory small block ford head found on a certain vehicles. They were most famous for their debut on the 1993 Cobra. GT40/GT40P heads were a more free flowing cylinder head that outperformed the factory E7 heads that were found on most 5.0 Fox Body Mustangs. To identify your GT40/GT40 heads, look for a "GT" or "GT40P" stamp inside the heads or a three bar (GT40) or 4 bar (GT40P) stamped on the side of the head.
What Is The Difference Between GT40 Heads vs GT40P Heads?
The GT40 & GT40P heads had a few differences that are note-worthy, the most importantly being the bump in compression. The GT40P heads had a small combustion chamber ranging from 58-61cc while the GT40 heads had a 63-66cc combustion chamber. The GT40 heads have thermactor holes built in to connect to the EGR/smog equipment whereas the GT40P heads us an external EGR connective system. The GT40P heads also had a different spark plug placement making header choice important. GT40P specific headers are needed unless you use spark plug wires with 90 degree boots to clear the heads
