The V8 Owners Forum -

i found a complete quad downdraught setup with 48mm dellorto drla's

i already have 4 x 40mm drla.

i was wondering what the 48's would be worth, they are in new / as new condition so i have been told.

i am only rly after the inlet or would i be better to stick with 48's and choke them rite down and sell the 40's????

I have seen this parts listed on other site and sent also an email to the seller.

Not yet recieved an reply. Do you know if it is an single piece manifold or two manifolds (one by side) ?

no i don't know, i spoke to the bloke already and he gave me a price, if i can sell the carbs for enuf i will buy them.

they are worth only £5. I will take them off your hands for you...

48 dellortos are in fact 45 choke dellortos with the lower 1/3 bored out to take a 48 throttle plate, the venturis are the same as 45 dellortos. If you have a set of 48 dellortos I would use them as they will be the ideal size for a 3.5/3.9.

PS. sell the 40's to Zander as they will go nicely on a 4.35 rover with chevy rods and pistons with a 4.2 rover crank, with buick 300 heads, a nice short duration hydraulic roller cam and a th 400 with a manual clutch conversion and a shift kit (that is until he builds the SBC he should have in the first place!!!)

Haha thanks for the encouragement mate! Maybe oneday I will fit a roller cam to my engine!

Though I already have my self a very nice reconditioned set of 36s which have all been balanced and 'apparently' set up for a 3.5 engine. We will see whether they are when I can eventually afford to finish building the bugger...

I could be interested in order to bling up my engine bay

Pse send me a PM with a price

Chroming your engine would have been cheaper!

I have to admit though, you cant beat a quad downdraft setup! Also, wouldnt it be a bit more 'correct' for a GT40 style car? I know most of the rear engined race cars from that period up until the late 70's had quad downdrafts.

Engine, Eales workover, exhaust etc - bills come to about £12k

It makes me wonder why the original builder decided on EFi when he was throwing so much money at it and a set of 4 carbs would be correct and probably give the same power output but be more thirsty. (But covering about 3000 miles a year how much extra would even 5mpg worse consumption actuall cost?)

that said a Ford mill would have been even more accurate

So not my choice at all but when the deal came along it became mine!

Now chroming it - that's worth thinking on - will it stop the Rover leaking oil?

ok well i think i will put in an offer for them, what size chokes would i need for my 3.9, stage 3, fast road cam engine?
