Im told it will be pretty hard to kill a tickford E series bottom end without boost. Would you agree?


There is no difference between a so called Tickford 4.0 EF and a bog stock EF bottom end. If you want to build a bottom end, start with an AU Block.



Thanks dude. I believe the compression is significantly more. For eg. My stock EA is 8.8:1 and the EF tickford is supposed to be around 9.5ish:1 and use hyperutectic pistons (forgive my spelling if thats wrong)
I have no ambition to alter the bottom end.


If the bottom ends are the same. How do you get 3.9L then 4.0L ?

I said that the bottom end is the same on the EF 4.0L and for that, the EL as well, except for the Hybrid in the late EL's.

I was under the impression the blocks are the same EF- EL, hybrid included? thought it was just the head that was different

whats the difference between a EF - Early EL Block and a Late EL Hybrid Block?

Cheers,
Tait

Late EL (hybrid) has larger mains on the crank.

Larger Mains are better. The EL Hybrid has the same mains as the AU and onwards.

I am running the 977B cam with a cms stage 3 head on my engine. I find the 977B cam is a perfect cam for everyday driving which will give you very good power and torque. I do find the cam lacks top end. It made max power at 4900rpm on my engine. But if i was to build a 1/4 mile engine i would run a cam with something like 225 to 235 degree cam at 50, a custom port job with larger valves, haltec sports 2000 a fresh up on the bottom end etc. If i was to go turbo set up i would use the 977B or the 1521a cam, a turbo spec head, haltec sports 2000 ecu, forged pistons with steel rods etc. One thing i have learnt about building a race engine is how deep are your pockets because skys is the limit.

I forgot to tell you try CamTech Cams in Sydney. Look at there web site, they have a huge rang of cams and will definitely help you in choosing the right cam for your application.
