In the Antipodes there is plenty of Nissan 3.0 litre blocks ( from VL Holden Commodore ) and RB2.6 Heads --which by the way is FAR better than 2.5 version--in the sense that it flows more. Rob at R I P has intake plenum and other stuff readily available if you don`t want to use TWR ( CA) T/B `s The 2900 series 48mm fit the intake port spacing exactley .

Yes correct --sorta ---I have a supercharged all alloy ford V 8 just about completed in Aust -in a 260 Z --The targa car has a RB 3.0 which produces 320 BHP ( engine dyno ) so will be more` streetable ` than the 380 HP engined car---- If I wasn`t technoligicaly challenged i could post a photo of the V8 in the Z in OZ. You are well in formed !!

I have a RB 3.0 ( VL commodore block and RB 2.6 head ) NA makes 380 BHP at 8100 RPM in NZ , DYNO figs ---very `peaky `

any one with a 240/260 shell sitting unloved for sale in florida ?

thank you Wayne,& sweetride2go,Photo is great and with info provided by you both I have the solution . Great site this ! cheers

douglas I just sold my share in Clayridge Vineyards ( Mike Just) so now have time and $`s to do what I want with the car Rytherwr--My engine is from Gregg Hekimain In MA--Gregg is concerned with the effect the 1-5/8 header will have on the flow --reversion even ---so Looks like I will have to relocate the steering much as you had to and box the frame also ---neither of which i wanted to do --but you have answered my question ,thanks appears it has to be done to make the fit

Thanks Douglas ---what are you running ? I really need 1 3/4 "so i don`t `strangle`all the wonderful HP shown on the Dyno------- It seems the steering shaft is a problem left or RH drive ---may have to `u`( or universal )joint it as I think some one has already suggested on another thread ----tube type headers obviously are better but too difficult to fabricate ---thanks for your input >

yes I know the know they are available ,Sanderson have a good set also ---question is will the they fit between chassis rails etc in Z

Has Anyone used 1 3/4 "header with SBC into Z ---or is the use of 1 5/8" the only way to go ? Have 400 making 630 HP ---1 5/8" too restrictive ,

anyone used 1 3/4 "block huggers with SBC in Z ? Do they fit --or Must I use 1 5/8"as everyone seemsdto ?

Sorry should have said SBC 406 re block huggers query

I need to know who produces block huggers which will fit angle plug---1 3/4 "
