Title: Carby set up for Repco x flow head Post by: fastjbav6 on December 13, 2004, 12:58:18 PM What carby and manifold set up did the Repco grey x flow head come out with and can this head be street driven or is it for racing only?

Usually twin Downdraught Webers. Fully streetable with the right cam. The manifold was a Repco item, that only fitted that head. Nothing else fits. Same with the extractors. Why?....................You got one?

I saw a 4BBL Holley manifold custom made for a Torana with extra long runners. It won't be original Repco, but it will get you going.

The crossflow kit was sold without manifolds. Manifolds and carbs were an extra, but Repco could supply them (twin 2bbl down draught Webers as Rob said) if needed. If you want a pic, just let me know. Cheers Tony Title: Re: Carby set up for Repco x flow head Post by: Burnsy on January 13, 2005, 12:22:03 PM Seb, as quoted from the Wheels Holden Handyman No 1.
The Highpower head using the original carburettor and 8 to 1 compression on a standard bore block gave out 90bhp at 5500rpm. Repco were eventually able to coax 130bhp out of the motor by adding twin choke down draft Weber carburettors, not the expensive type fitted to Ferraris and Maseratis but the type fitted to production family saloons. Whilst on the topic, can anyone name some of the "family saloons" that were fitted with twin choke webers?

GP Title: Re: Carby set up for Repco x flow head Post by: Burnsy on December 27, 2005, 02:15:56 PM Just a quick update on these downdraft carbies being discussed previously. GP is right they were fitted to early 124 Fiats and also some early GT cortinas. They are 28/36 DCD webers and are also what was recommended by Thomas for their twin downdraft manifolds - coming soon to a Green EK ;D

These Webers were not only fitted to Fiat 124s, but also to most of the large 60s sedans. I have a 1965 1800b (1.8ltr 6cyl) which has a 28-36 DCD 2. The 28-36 DCD 3 was fitted to 2300s, can't readily identify the differences now . They may also have been fitted to the 4 cylinder 1500s. The code refers to the 28mm primary and 36mm secondary throats. I have detailed drawings of these carbs, complete tune-up info and may be able to help you locate one/two if need be. If you need some help, send me a pm. cheers John ;D Title: Re: Carby set up for Repco x flow head Post by: Johns on December 28, 2005, 11:28:36 AM Re my previous post.
The DCD 2 has primary and secondary throats (as opposed to bores) of 21mm and 23mm. The DCD 3s are 23/25mm. The DCD 3 may be the one to go for. regards John |
